Biology
1 answer:

Answer:

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.

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 <u>species colonize new, previously inhabited areas with no soil.</u> 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 <u>a previously inhabited area is re-colonized after a disturbance.</u> It begins with grasses, then followed by shrubs, and finally with trees before fauna species can also appear.
