a. It shows how energy stored in food moves from one organism to another.
The food chain illustrates the law of conservation of energy by showing how energy is transferred from one organism to another as it is consumed. The energy from the sun is captured by plants through photosynthesis, then passed along to herbivores that eat the plants, and then to carnivores that eat the herbivores. Energy is never created or destroyed in this process, only transferred from one organism to another.
The diagram below shows a food chain.
How does this food chain illustrate the law of conservation of energy?
a
It shows how energy stored in food moves from one organism to another.
b
It shows that the energy used by plants for photosynthesis disappears.
c
It shows that energy is destroyed by the last animal in the chain.
d
It shows how sunlight is converted into the matter making up organisms.
