Consider the following statements about biological communities. I. Their members share a common gene pool II. The community remains stable even though some physical aspect of the environment may undergo a change III. It consists of all the populations living in a particular area. IV. A community interacts with a non-living environment and both function together to form an ecosystem Which two of the above statements are true?

Explanation

Different living and nonliving things in a single habitat form a single community. Since different species are present they have different characteristics so the gene pool is not the same. Change in the environment does cause a change in the balance of genes in the environment so the community does not remain stable. The last two statements iii and iv are right that as previously mentioned the community is all the population living in a particular area. Secondly, the community involves biotic(living) and abiotic(non-living) factors interacting with one another.
