An ecosystem consists of biological communities and these factors
What are abiotic factors?
300
Decomposers feed from this/these trophic level(s)
What are ALL trophic levels?

Burning of fossil fuels can release this gas in to the atmosphere, accelerating climate change by contributing to the greenhouse effect
What is CO2?
400
These release excess H+ atoms when dissolved in water
What are acids?

What is chemical energy?
400
A group of whales presently living in cape cod, the krill that they eat, and the barnacles living on the whales back would be an example of this
What is a biological community?
400
At the tertiary consumer level, this percentage of the original energy from the sun is utilized

What are cellular respiration and chemosynthesis?
500
This factor, labeled in the diagram above, distinguishes this as an ecosystem, rather than a biological community
What is the sun?
500
This percent of energy is "lost" between each trophic level
What is 90%?
