Question

Which of the following characteristics are seen in a stable community?

1. It is strong enough to withstand environmental disturbance and recovers quickly.
2. It is resistant to invasive species.
3. It exhibits constant change in biomass production over a period of time.
4. It has more species diversity.

Options

• i, iii and iv only

• i, ii and iv only

• i, ii and iii only

• ii and iv only

Answer 1

i, ii and iv only

Explanation:

A stable community can recover quickly from disturbances (i), is resistant to invasive species (ii), and has high species diversity (iv), which increases stability. However, biomass production is not constantly changing in a stable community, so statement (iii) is incorrect.
