Question

Compare primary and secondary succession. What is the distinction between them?

Primary succession is the sequence of species that become established early in a newly colonized area, and secondary succession is the sequence of species that move in later.

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.

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 with no soil.

Primary succession is the sequence of plants that colonize a new area, while secondary succession is the sequence of animals that move in later.

Answer 1

B. 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.

Step-by-step explanation:

In Biology, ecological succession refers to changes in the structure of the populations of species that inhabit a specific area.

Primary succession starts when species colonize new, previously inhabited areas with no soil. The species that appear first are known as pioneer species that do not require a great amount of nutrients or soil, for example lichens.

Secondary succession refers to a situation in which a previously inhabited area is re-colonized after a disturbance. It begins with grasses, then followed by shrubs, and finally with trees before fauna species can also appear.
