Name an organism that removes atmospheric carbon dioxide.

Any type of plant

100

What are the inputs and outputs of cellular respiration?

Inputs: glucose and oxygen

Outputs: carbon dioxide, water, heat, and ATP

100

Burning of muscles is called __________ and is a product of __________________.

lactic acid; fermentation 

100

What are the three different types of pyramids used to measure?

Energy, biomass, and population size 

100

What do decomposers do and why is it important?

Breakdown dead and decaying things. This returns nutrients back to the soil and atmosphere. 

200

What are the inputs for photosynthesis?

Sunlight, water, and carbon dioxide 

200
What product of cellular respiration allows muscles to contract?

ATP

200

What is the relationship between photosynthesis and cellular respiration?

The products of one process are the reactants of the other process. 
200

If you have 1,500 J at the primary consumer level, how much energy does the secondary consumer level receive? 

150 J 

200

Does burning fossil fuels add carbon or remove carbon from the atmosphere?

Adds carbon

300

In light dependent reactions of photosynthesis, what is the  input and output received? 

Inputs: sunlight and water

Output: oxygen

300

In our yeast lab, what evidence was there for aerobic respiration taking place?

Carbon dioxide was produced and caused the balloon to inflate. 
300

Is matter and energy lost in an ecosystem? Explain why the amounts available change for different trophic levels.

Matter and energy are always conserved, so none is lost in an ecosystem. 

All energy is not passed on to the next trophic level, however, because the organism uses some for cellular processes, waste, and heat. The only portion passed on to the next trophic level is the amount of energy used by that organism for biomass. 

300

If the primary producers obtain 1,400 J of energy, how much is available for the secondary consumers?

Primary consumers: 140 J

Secondary consumers: 14 J

300

Give me a simple food chain specific to animals that we see in Iowa.

Example:

Grass --> Rabbits --> Eagles


400

In light independent reactions, what is the input and output in photosynthesis?

Input: carbon dioxide

Output: sugar

400

What evidence was there for anaerobic respiration in our yeast lab?

The balloon continued to inflate once the oxygen was all consumed and ethyl alcohol was produced. 

400

Is ATP only produced under aerobic conditions?

No, ATP can be produced during fermentation for a short amount of time, which is an anaerobic process. 

400

In a food chain, you have grass --> rabbits --> snakes. What happens to your population of snakes if your plant population declines by 50% due to a fire?

You population of snakes will be greatly reduced as well. The rabbits will go down by 50% as well as the snake population. 

500

What are some plant adaptations to their environments and give an example of the plant. (Hint: think back to C3, C4, and CAM plants)

C3 and C4 plants are not concerned with conserving water so they open their stomata during the daytime. Example: corn

CAM plants are concerned with conserving water and open their stomata at night. Example: cacti 

500

Does fermentation produce ATP in our bodies? Why can our bodies only do this for a short time?

Yes! A result of fermentation in our bodies is lactic acid however and this is why our bodies can only sustain the production of ATP for a very short amount of time. 

500

Why are there so many more organisms at the primary producers level in an ecosystem than the tertiary consumers? 

There is not enough energy passed on at each level to support a large population of organisms that are higher up the food chain. Only about 10% of energy is passed on so the closer you are to getting the energy directly from the sun, the larger that population of organisms is. 

500

How can you figure out the energy transfer efficiency to each trophic level?

This would be the percentage passed on to each level. An average passed on is 10% to each trophic level per ecosystem but this does vary slightly. 

500

How does the loss of phytoplankton impact the amount of carbon available in atmosphere?

Phytoplankton are producers in the ocean, meaning they are photosynthetic. They remove carbon dioxide and add oxygen to the atmosphere. If the population declines then the amount of carbon dioxide builds up in the atmosphere and there is less oxygen available as well.
