DCP Review # 3

Which statement about the proposed law is supported by the model?

• The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake.

• The proposed law will not protect the lake because animals that live in or near the lake will add pollution to the lake.

• The proposed law will not protect the lake because groundwater will carry pollution from the wetland directly into the lake.

• The proposed law will protect the lake because the high elevation of the water table will block pollution from entering the lake.

Which statement BEST describes the flow of energy through this pyramid?

• Producers provide energy directly to the organisms in all the trophic levels above them.

• Primary consumers transfer energy to the trophic level above them and the trophic level below them.

• Secondary consumers represent the most organisms, and they have the greatest amount of energy in their trophic level.

• Tertiary consumers do not receive all the energy from the trophic level below them, because some energy is lost to the environment.
