Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest is

• used in reproduction.

• stored as body tissue.

• stored as fat.

• eliminated as heat.

Biogeochemical cycling ensures that

• human activity will have no effect on elements, chemical compounds, and other forms of matter.

• living organisms will not become limited in any one nutrient.

• nutrients will be circulated throughout the biosphere.

• many nutrients will not reach toxic concentrations in the biosphere.

Bears are considered what type of consumer?

• Herbivore

• Omnivore

• Carnivore

• Decomposer

No two species can occupy the same niche in the same habitat at the same time

• because of the interactions that shape the ecosystem.

• unless the species require different abiotic factors.

• because of the competitive exclusion principle.

• unless the species require different biotic factors.

What is one difference between primary and secondary succession?

• Primary succession is rapid and secondary succession is slow.

• Secondary succession begins on soil and primary succession begins on newly exposed surfaces.

• Primary succession modifies the environment and secondary succession does not.

• Secondary succession begins with lichens and primary succession begins with trees.
