Question

select the correct answer.
which statement correctly describes a feature of carrying capacity?
a. can only change if the population experiences migration
b. can only be calculated for species with a uniform population distribution
c. can only be attained by organisms that follow the type i survivorship pattern
d. is a constant for all populations of the same species
e. may change as environmental conditions change

Explanation:

• Option A: Carrying capacity (K) changes due to environmental factors (e.g., resource availability, climate) not just migration. Eliminate A.
• Option B: Carrying capacity can be calculated for any population, regardless of distribution (uniform, clumped, random). Eliminate B.
• Option C: Carrying capacity is not limited to Type I survivorship (e.g., Type II/III species also have K). Eliminate C.
• Option D: K varies by environment (same species in different habitats have different K). Eliminate D.
• Option E: Environmental changes (e.g., food, space, climate) directly affect K, so K may change with environment. This is correct.

Answer:

E. may change as environmental conditions change
