Answer 1

The correct options are as follows;
1. A.
The ecosystem is made up of abiotic and biotic components. The abiotic components refers to the non living component of the ecosystem while the biotic components refers to the living part of the ecosystem.

Decomposers feed on dead organic matter and decompose them in order to make the nutrients in them available to the soil. Soil fertility usually increases as the result of the activities of the decomposers. The nutrients released into the soil are used as food for growing plants.
6.D
Diversity is the biological word that is used to describe the different species of plants and animals that are present in a particular ecosystem. The higher the different species of living organisms that are present in an ecosystem, the higher the biodiversity. The higher the biodiversity of an ecosystem, the better is it for the survival of the organisms in that particular ecosystem.
