Which of the following is true of a food chain? A food chain—
shows the movement of energy through an ecosystem
is exactly the same as a food web in every ecosystem
never contains any green plants or other producers
consists only of predators, prey, and decomposers

Plants use this oxygen to make water
People need this oxygen to make electricity
Animals use oxygen for food
Living things need oxygen for respiration
seeds > mouse > red-tail hawk
In the diagram above, what do the arrows represent?
Photosynthesis
The life cycle of an organism
The transfer of energy
Nourishment (energy)
Decomposers are helpful to the food chain because they —
place nutrients in the soil
prey on carnivores
use photosynthesis to make food
are food for carnivores
Many animals depend on plants for—
carbon dioxide
pollination
seed dispersal
nourishment
What is the role of a producer in a food chain?
Preys on animals
Eats decayed animals
Makes food
Eats plants
