Which two sentences best explain what happens to energy in this
ecosystem?
A. Each organism gains energy from its surroundings.
B. Energy is lost as it flows through the links in a food chain.
C. Each organism loses energy as body heat.
D. Energy is gained as it flows down the pyramid.

Explanation: Each time an organism consumes another one the energy is lost by 90%. So an animal will only ever receive 10% of the initial energy.

If a producer has 100 J of energy and a deer comes to eat it they only will get 10%, so 10 J. If a mountain lion eats the deer it will only get 1 J, because the 10% rule. Each time another organism consumes another use the 10% rule.
