Question

Compare primary and secondary succession of an ecosystem. What is the distinction between them? A) Primary succession is the sequence of plants that colonize a new area, while secondary succession is the sequence of animals that move once plant life is established. B) Primary succession is the sequence of species that become established early in a newly colonized area, while secondary succession is the sequence of species that move in much later. C) Primary succession is the establishment of a new community in an existing ecosystem that was disturbed, while secondary succession is the establishment of a community in an area that was altered due to fire. D) Primary succession is the establishment of a community in an area with no soil, while secondary succession is the establishment of a new community in an existing ecosystem that was disturbed by some catastrophic event.

Answer 1

Ecological succession refers to the process of change in the species structure of community over time. It has four stages and involves two different types: the primary and the secondary succession.

Primary succession occurs in an area that has no signs of life, while secondary succession takes place in an area where life previously existed but was disturbed or removed.

Thus, the correct answer is D.
