Question

Ecological succession on sandy soil is known as-- 1)hydrosere, 2)xerosere, 3)psammosere, 4)halosere.

Answer 1

Answer:

3) psammosere

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades  or even millions of years after a mass extinction.

A psammosere is a seral community, an ecological succession that began life on newly exposed coastal sand. Most common psammoseres are sand dune systems.

Thus option "3) psammosere " is correct.

Answer 2

Answer:

Explanation:

The ecological succession on sandy soil is known as psammosere where the beginning of the succession is from the sandy habitat.

The moisture at these kind of places is too minimal that it has evasive effects and it is totally on the climatic and geographic conditions of that particular place.

Here the sandy habitat is the main catalyst for the ecological succession.
