The correct answer is option A(1). Hence Secondary succession is found in estuaries.
<h3>Explanation:</h3>
There are two types of successions:
Primary succession and secondary succession.
Secondary or optional progression is a reaction to an aggravation, for instance, woodland fire, wave, surge, or a deserted field.
It happens when an ecosystem existed but has been disturbed.
An estuary is a mostly encased seaside collection of saline water with at least one waterways or streams streaming into it, and with a free association with the vast ocean. Estuaries frame a progress zone between stream situations and sea conditions.
Some any type of natural disaster like storm in estuaries will be an example of secondary succession.
An array of community modifications that occurs on a previously colonized, but damaged or disturbed habitat is known as secondary succession.
For example, in estuaries, the secondary succession could be demonstrated by a hurricane coming to an already fertile estuary, damaging the majority of animals and plants, and then other species come and re-populate the region that is already fertile.
