Based on the graph, which of the following conclusions about the distribution of these two species can be reached?

• Both shrimp species avoid high-salinity habitats because dissolved salt interferes with shrimp reproduction and growth.

• Both shrimp species prefer moderate-salinity habitats over low-salinity habitats because salt facilitates cellular processes required for survival.

• The two shrimp species thrive in water with different salinities because each species has adapted to living in water with certain amounts of salt.

Which of the following best describes the transfer of energy in this energy pyramid?

• The amount of energy that flows between organisms within each trophic level remains constant.

• Energy flow increases when organisms move from one trophic level to another within an ecosystem.

• Energy flow is greater between the two upper trophic levels than between the two lower trophic levels.

• The amount of energy that flows from one trophic level to the next is related to the productivity of the lowest trophic level.

In recent decades rainforests throughout the world have been cut down for various reasons. In some cases the wood has been used; in others, the land. The deforestation of Earth's rainforests has resulted in

• the rapid extinction of many species on Earth.

• primary succession and evolution of new habitats.

• habitat destruction and the overall decrease in biodiversity.

• secondary succession and the development of new, successful ecosystems.
