What is the main concern regarding environmental policy decisions?

• They should be based on the cost and benefits of renewable resources.

• They should ensure the reduction of available energy at successive trophic levels.

• They should be made after adequate monitoring of environmental parameters.

• They should focus on the water and carbon cycles.

Coyotes are opportunistic predators that are found throughout most of North America. They typically feed on small mammals, insects, and fruits and vegetables. They are known for their dietary adaptability. The best description of their role in the food web would be:

• An herbivore

• A carnivore

• An omnivore

• A primary producer

A food chain is illustrated below:

• Energy released from metabolism into the environment as heat.

• Oxygen released from metabolism produced by cellular respiration.

• The absorption of energy from the environment that has been created.

• The transport of glucose away from the organism through photosynthesis.

If several species of carnivores are removed from an ecosystem, the most likely effect on the ecosystem will be:

• An increase in the kinds of autotrophs

• A decrease in the number of abiotic factors

• A decrease in stability among populations

• An increase in the rate of succession

Which statement describes an interaction that helps maintain the dynamic equilibrium of this ecosystem?

• The frogs make energy available to this ecosystem through the process of photosynthesis.

• The algae directly provide food for both the rotifers and the catfish.

• The green-backed heron provides energy for the mosquito larvae.

• The catfish population helps control the populations of water boatman and water fleas.

Why is a mushroom considered a heterotroph?

• It creates different types of food.

• It makes food through photosynthesis.

• It makes food through chemosynthesis.

• It obtains nutrients from its environment.
