Explanation:

Question 22

Trees in an apple orchard planted in even rows are spaced regularly, so the dispersion pattern is uniform. Clumped is grouped, random is unordered, and radial is from a center. Uniform matches the even - row planting.

Habitat destruction is a major threat to endangered species as it reduces their living space, food sources, etc. Overpopulation of predators is less common as a main threat, increased rainfall is not a main threat, and genetic diversity is beneficial, not a threat.

An S - shaped (logistic) population growth curve has a growth rate that slows as the population approaches the carrying capacity (K). Population doesn't crash after K, growth rate isn't constant, and it doesn't grow without bounds (that's exponential, J - shaped).

Answer:

c. Uniform
