Why Was It Important That We Waited A Year To Perform Our Second Population Estimate?

Which of the following is a reason why predation might increase the bluegill’s mass to length ratio?

What effect did the introduction of the predators have on the bluegill population? … The mass increases relative to the length because the bluegills that are too wide to fit into the mouth of the bass have a greater chance of survival.

What was the range of the bluegills length remember it is the difference between the largest and smallest value?

What was the range of the bluegills’ length in Part I? Remember it is the difference between the greatest and least value. For example if the greatest length was 100 cm and the least length was 70 cm the range of the length would be 30 cm.

What was the range of the bluegills length?

SIZE: Common length for bluegill is 19.1 cm (7.5 inches) with the maximum reported length being 41 cm (16 inches). RANGE: Bluegill range in North America extends from Canada to northern Mexico.

What are two other environmental factors that could affect the bluegill population?

In an undisturbed environment bluegill populations are only affected by natural pressures like water clarity predator types and abundances and lake size.

What is the primary role of a decomposer in the chemical cycling of elements in the biosphere quizlet?

What is the primary role of a decomposer in the chemical cycling of elements in the biosphere? Decomposers break down large organic molecules into smaller more accessible nutrients.

Why does temperature affect oxygen production?

Higher kinetic energy increases the number of collisions between the enzymes and substrates of the light reactions ultimately resulting in a higher photosynthetic rate (Lambers et al. 2008). reactions would slow down accordingly. thus decrease the rate of oxygen production.

Why did the volume increase in the gas syringe?

Why did the volume increase in the gas syringe on the Elodia vial? Oxygen was produced through photosynthesis increasing gas in the syringe. … CO2 Sunlight and Water (for hydrogen) are required to produce oxygen and glucose.

How can the rate of photosynthesis change its volume?

Subtract the original volume at 0 min from the final reading at 120 min to determine the volume change. Divide the change in volume by the time 120 min to obtain the rate of O2 production in units of mL/min.

What affects the bluegill population?

Like other forces acting on populations of bluegill Lepomis macrochirus internal processes such as recruitment and growth and external influences such as predators lake characteristics and temperature will ultimately affect a population’s size structure and determine whether the population is stunted or has a …

How is the cycling of water important to the cycling of other materials?

Explain how the cycling of water is important to the cycling of other materials that are essential for terrestrial and aquatic ecosystems. … phosphorous cycle: the water weathers the rock which causes it to break down into soil which plants then use/ absorb phosphorus into their roots.

How can decomposers disrupt the balance of an ecosystem?

Decomposers (Figure below) get nutrients and energy by breaking down dead organisms and animal wastes. … Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

What are important elemental cycles in the environment?

There are a lot of things that come together to form a functioning ecosystem but there are three cycles that are key to understanding the big picture: the water cycle the carbon cycle and the nitrogen cycle.

How does the color of light affect photosynthesis?

The lights higher on the light spectrum like blue would have the fastest rate of photosynthesis because the energy is the highest. The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light so it would not be absorbed as much as the other colors.

What color of light is best for photosynthesis?

green light
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.Feb 6 2014

How does the color of light affect the rate of photosynthesis quizlet?

The color of light affects the rate of photosynthesis when the production of oxygen increases at 450 nm (blue) drops then rises again at 660 nm (orange). … When we look at a leaf we usually see the color green. This green represents the green light which has a low flow of oxygen.

What is the importance of gas laws in our daily life?

Amontons’ law states that “At constant volume as the temperature of a gas doubles its pressure also doubles.” Example: It is important to check the pressure of the car tire before heading to a drive. While driving the temperature of the air in the tire increases and results in flexing.

Why is a syringe of larger volume used in Boyle’s law experiment?

The air can escape through the opening at the tip of the syringe. … This time you decrease the pressure of the air inside the syringe—and its volume increases. As a result the air-filled balloon expands and grows in size: a perfect demonstration of Boyle’s law!

What will happen if the plunger will be pushed down the syringe?

There is a fixed number of molecules of air inside of the syringe. When the plunger is pushed in these molecules begin to push (or collide) against each other and the sides of the syringe more and more because of the lack of space. This decrease in volume (less space) increases the pressure (more collisions).

Why is photosynthesis so crucial to life on Earth?

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis the carbon cycle could not occur oxygen-requiring life would not survive and plants would die. … The importance of photosynthesis in our life is the oxygen it produces.

How can the rate of photosynthesis be increased?

Light intensity

See also where is the cold desert located

Without enough light a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis until some other factor – a limiting factor – becomes in short supply.

How do plants metabolize the sugars they produce by photosynthesis?

The correct option is (b) by cellular respiration. Plants use the energy accumulated during the photosynthetic process to digest the sugars they synthesize by cellular respiration which plants use the stored energy during photosynthesis.

Are bluegill good for ponds?

“They’re a great kids’ fish.” “They’re easy to catch.” “They’re a good management option for a pond too small to manage for trophy bass.” If you’re a serious bluegill angler chances are you’ve heard someone denigrate your favorite fish.

How old is a 8 inch bluegill?

At 2 years of age: Bluegill will likely fall between 6.5 and 8 inches. At 3 years of age: Bluegill will likely fall between 8 and 8.9 inches.

Are bluegill good eating?

Yes you can eat Bluegill. They are an abundant fish species found all over North America and are considered very good table quality by anglers. The meat is firm mild-flavored and best prepared fried or cooked whole.

Why is important the water cycle?

The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn’t naturally recycle itself we would run out of clean water which is essential to life.

Why is matter important to cycles of nature?

The cycling of matter is important to many Earth processes and to the survival of organisms. … So existing matter must cycle continuously for this planet to support life. Water carbon nitrogen phosphorus and even rocks move through cycles. If these materials did not cycle Earth could not support life.

What would happen if the water cycle was disrupted?

The water cycle brings water to everywhere on land and is the reason that we have rain snow streams and all other kinds of precipitation. Stopping it would cause an endless drought. … No water flow in lakes would cause overgrowth killing many species of fish and other lake wildlife.

Why are decomposers important?

Decomposers play an important role in the circle of life—without them waste would just pile up! … Decomposers are made up of the FBI (fungi bacteria and invertebrates—worms and insects). They are all living things that get energy by eating dead animals and plants and breaking down wastes of other animals.

What would happen if decomposers were removed from the carbon cycle?

Decomposers Recycle Carbon

Plants and phytoplankton are then consumed by other organisms up the food chain. When these organisms die the carbon remains locked in their bodies. … Without decomposers the carbon would remain locked in dead organisms and could only be released through combustion.

What would happen if an ecosystem lacked decomposers?

Decomposers break down the dead remains of plants and animals and release the nutrients such as carbon nitrogen etc. In the absence of decomposers in the environment this breakdown will not occur and hence the nutrients will not be released. Due to this plants will not get sufficient nutrients.

Why is it important for an ecosystem to be sustainable and balanced?

Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological balance is also important because it leads to the continuous existence of the organisms. It ensures that no particular species is exploited or overused.

How are the different cycles important to living things?

Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on such as carbon nitrogen and phosphorous are in constant circulation. Essential elements are often stored in reservoirs where they can be taken out of circulation for years.

Why is nutrient cycling so important in ecosystems?

Nutrient cycles restore ecosystems to the equilibrium state and therefore play an important role in keeping the ecosystem functioning. All organisms living and non-living depend on one another. Nutrient cycles link living organisms with non-living organisms through the flow of nutrients.

Why is light intensity important for photosynthesis?

As you rise from low light intensity to higher light intensity the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. … At a very high intensity of light the rate of photosynthesis would drop quickly as the light starts to damage the plant.
