Question

Which of the following is a factor that can prevent the unlimited growth of a species that initially demonstrates geometric or exponential growth rates?

a) Limited space
b) Limited resources
c) Limited suitable habitat d) All of the above

Interspecific competition will be greatest in species . . .
a) That share identical resource requirements.
b) That have distinct resource requirements.
c) Where one species is native and one species is invasive. d) Where both species are native and endemic to a region.

A species with low adult mortality and that delays reproduction to invest energy into survival and growth is most likely a:

a) K-selected species b) N-selected species c) r-selected species d) Keystone species

A species that has a disproportionately large influence on the structure of their community relative to their abundance or size is considered a:

a) Dominant predator b) Climax species
c) Barnacle
d) Keystone species

In Consumer-Resource interactions, one species gains a fitness advantage at the cost of another species. Which of the following is an example of a Consumer-Resource interaction?

a) A squirrel uses a hole in a tree as shelter
b) A dragonfly kills and eats a beetle
c) A grouper is cleaned of parasites by a cleaner shrimp
d) Endosymbiotic algae grows inside the tissue of a coral and produces nutrients for both

Energy pyramids in all biomes are bottom heavy (i.e. the largest amount of energy available at the lowest trophic level). Biomass pyramids in most biomes are also bottom heavy, but not in the open ocean which have an inverted pyramid pattern. Why?

a) Because there are no primary producers in the open ocean
b) Because there is a rapid rate of turnover at lower levels and little standing biomass c) Because there is a slow rate of turnover at lower levels and a large standing biomass d) Because of heavy exploitation of low trophic level species by humans
