200
An example of this is a grass plant in a lawn.

300
The process where organisms use chemical energy to produce carbohydrates

300
The process by which nitrogen is lost or removed

400
A group of organisms that share the same position on a food chain
What is a trophic level?
400
The pathway by which a chemical substance moves through both biotic and abiotic Earth
What is a biochemical cycle?

500
An organism that relies on other organisms for their energy and food supply
What is a heterotroph?
500
The process where plants absorb water through their roots and then give off water vapor through pores in their leaves
What is transpiration?
500
The two categories of organisms for which energy transfers from the former one (the first category) to the latter one (the second category)
What are autotrophs and heterotrophs (producers and consumers)?
500
