5.2 - Biomass & Energy Pyramids Review

If there were no decomposers, what would happen to the dead tree?

• The tree would stay on the ground and take up space

• Nutrients would not be returned to the soil

• Plants would not have the nutrients for biosynthesis

• All of these would happen.

If a rabbit eats 50 grams of grass a day, but only gains 2 grams, where does the rest of the mass go? Match each type of matter to it's process.

• defecation

• water

• cellular respiration

• feces

• urination

• carbon dioxide

• Grass

• 5 joules

• Grasshoppers

• 50 joules

• Eagles
