200
The type of anaerobic fermentation used in human muscle cells during periods of great exertion.
What is lactic acid fermentation?
200
Two terms for the trophic level in which organisms photosynthesize.
What are producers and autotrophs?
200
The trophic level that breaks down organic matter and recycles it.
What are decomposers?
200
The part of the day when plants release more CO2 and they absorb.
What is nighttime?
200
The key organisms that bring atmospheric nitrogen to the biosphere.
What are nitrogen-fixing bacteria?
300
Organisms that primarily use anaerobic respiration.
What are bacteria and fungi?
300
All of the primary consumers in this food web.

What is the burning of fossil fuels?
400
The biogeochemical cycle that rarely involves the atmosphere.
What is the phosphorus cycle?
500
The name of the process shared between aerobic and anaerobic respiration and how much ATP is produced during that process.

500
Two impacts of the loss of trees in this food web.
What are: a decrease in deer and bees and an eventual decrease in mountain lions and grasshoppers?
500
The most critical trophic level in an ecosystem and why.
What are producers/autotrophs because they are the only ones who can convert sunlight energy into a form usable by organisms?
500
The relative ability of the ocean to absorb CO2 as temperatures rise due to climate change.
What is decreasing?
500
The phenomenon shown in the image and a possible human cause for it.
