Question

In some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters?

		a keystone organism
		a decomposer
		a crustacean
		a superior predator
		a producer

The composition of a community refers to the

		nutrients available in the soil.
		type of succession that occurs locally.
		sunlight available to drive the energy needed for metabolism.
		extent vegetation covers the ground--a desert has low composition.
		types of species adapted to living there.

Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating. The relationship between the shark and the small fish is an example of

		co-evolution.
		parasiticism.
		mutualism.
		commensalism.
