Which describes an example of ecological succession?
a) a caterpillar developing into a butterfly.
b) a meadow replacing a pond in its flood plain.
c) a climate gradually changing over many eons and becoming colder.
d) the replacement of a native species of animal with an invasive species.

The correct option is B: A meadow replacing a pong in its flood plain

Explanation:

Ecological succession is the process of change in ecological communities during which the species structure gradually change with time. Species structure within an ecological community keeps changing with time until a relatively stable community, otherwise known as climax community is reached.

Depending on the status of the habitat, succession are of different types;

Both primary and secondary succession in ecological communities eventually lead to formation of stable climax communities if left undisturbed. The species structure will keep changing till a relatively stable community structure is established.

A meadow which is a type of grass replacing a pond in its flood plain is an example of ecological succession in an aquatic community. In this case, the species within the flood plain is being replaced by grasses. The replacement of native species of animal with invasive species cannot be considered as succession but rather an invasion.

Hence, the correct option is B.
