If an ecosystem has a carrying capacity of 1,000 individuals for a given species, and 2,000 individuals of?

Question

that species are present, we can predict that the population

A. will show a clumped dispersion pattern

B. Size will slowly increase

C. will show a uniform dispersion pattern

D. size will decrease

E size is at equilibrium

Answer 1

Well.. if you only have so much room for a given number of individuals (in your case, 1000), by doubling this amount, competition for resources (e.g.: shelter, food) becomes greater increased and naturally, more individuals will die off because they can't meet the requirements to survive (e.g.: too many individuals fighting for too few resources).  The size is at equilibrium again when the number of individuals drops to 1000.

[Answer: D]
