How does energy transfer from one trophic level to the next in an ecosystem?
Through the consumption of organisms at a lower trophic level
Through the absorption of sunlight
Through the decomposition of dead organisms
Through the release of heat
How do the biosphere and atmosphere interact in the carbon cycle?
Plants in the biosphere absorb carbon dioxide from the atmosphere during photosynthesis
Animals in the biosphere release oxygen into the atmosphere during respiration
The atmosphere provides nutrients to the biosphere
The biosphere and atmosphere do not interact

Mutualism
Parasitism
Commensalism
Predation
Which of the following best describes the interaction between the lithosphere and the hydrosphere?
