Group of answer choices

The correct answer is number 3. fragmented, disturbed, r, early.

Ecosystems in human-dominated landscapes are generally fragmented and disturbed, and support more species with r - selected reproductive strategies, and are typical of early succession.

Explanation:

Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.

r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.

As human-dominated landscapes are generally fragmented and disturbed, new areas are constantly available for r species to colonize them. This is an early stage of succession when these r species arrive in the open perturbated space and colonize it. These r species start a modification in the habitat that makes it suitable for the posterior establishment of later K species. As conditions get better, competition becomes more frequently between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources.
