C Producers can absorb the sun's energy to make food.
D Producers are healthiest to eat.
In what way does plant nutrition differ from human nutrition? Choose the best answer.
A Plants make their own nutrients; humans must consume theirs.
B Plant nutrition consists mainly of protein; human nutrition consists mainly of carbohydrates.

D herbivores eat only plants; omnivore eat only plants; carnivores eat mostly plants
If the population of trees were destroyed due to deforestation (removal of forest by humans) what is the most likely outcome of this food chain? Use the image above to help.

B Decomposers return nutrients to the soil
C Decomposers eat plants, which are eaten by animals
