Question

which of the following best describes ecological succession? a sudden replacement of one plant community by another a natural, gradual change in the types of species that live in an area a process that only occurs in aquatic environments a rapid change in the types of species in an area

Explanation:

Ecological succession is a natural, gradual process. It involves the change in species composition over time in a given area. It is not sudden (so the first option is wrong). It occurs in both aquatic and terrestrial environments (so the third option is wrong). And it is a gradual change, not a rapid one (so the fourth option is wrong).

Answer:

A natural, gradual change in the types of species that live in an area.
