Chapter 4 Section 1 Review

Gerald is studying the plants and animals of a meadow. He classifies the grasses

and clover as (autotrophs / consumers / decomposers / heterotrophs) because

they make their own food through the process of (chemosynthesis /

decomposition / photosynthesis / regurgitation). He classifies insects that feed

on the clover as (carnivores / detritivores / herbivores / omnivores) because he

thinks they eat only plant matter, not animal matter.

Plants are

• Primary producer

• Consumer

Animals are

• Primary producer

• Consumer

Fungi are

• Primary producer

• Consumer

Bacteria that perform chemosynthesis are

• Primary producer

• Consumer

Bacteria that perform photosynthesis are

• Primary producer

• Consumer

Which statement describe ALL primary producers?

• All make energy-rich compounds that can be used by other organsims

• All make their own food using the energy of compounds in the environment

• All take in energy-rich compounds that were made by other organisms

• All make their own food using the energy of sunlight.

Scientists classify clams as consumers. Which observation about clams provides the strongest evidence for this classification?

• Young clams are able to move from place to place

• Calms gain energy and nutrients by filtering particles from the water

• Clams use calcium compounds to make a hard shell

• Clams live on the ocean floor, and sometimes without sunlight

Which of the following is modeled in the diagram?

• a. The role of photosynthesis in breaking apart carbohydrates for their energy

• b. The role of photosynthesis in adding carbon dioxide to the atmosphere

• c. The role of photosynthesis in transferring carbon from the atmosphere to the biosphere

• d. The role of photosynthesis in transferring carbon dioxide from the hydrosphere to the biosphere
