Ecosystem Restoration

After a zebra eats grass, what happens to the grass molecules inside the zebra (use your ideas from the previous unit on chemical reactions) ?

• There is a chemical reaction taking place in which the the grass molecules are turning into zebra body molecules.

• There is not a chemical reaction taking place.

• The zebra is made of grass molecules.

• There is a chemical reaction taking place in which the the zebra molecules are turning into grass molecules.

According to the Healthy Ecosystem Model, what happens to the zebra molecules once they are eaten by the cheetah?

• The zebra molecules turn into chetah body molecules.

• The zebra molecules are released as energy so the chetah can move and grow.

• The zebra molecules turn into cheetah body molecules or are released as energy so the cheetah can move and grow.

• There is no change to the zebra molecules.
