• A. A-(iii), B-(ii), C-(i), D-(v)
• B. A-(iv), B-(v), C-(iii), D-(i)
• C. A-(ii), B-(iii), C-(i), D-(iv)
• D. A-(iii), B-(ii), C-(iv), D-(i)

Answer 1

The correct option is D A-(iii), B-(ii), C-(iv), D-(i)

Column I	Column II
A. Population	A group of individuals of the same species occupying a particular geographic area. Populations may be relatively small and closed, as on an island or in a valley, or they may be more diffuse and without a clear boundary between them and a neighboring population of the same species. So the correct option is 'group of similar individuals belonging to same species, found in an area'.
B. Community	A community is a small or large social unit (a group of living things) that has something in common, such as norms, religion, values, or identity. Communities often share a sense of place that is situated in a given geographical area (e.g. a country, village, town, or neighborhood) or in virtual space through communication platforms. Although communities are usually small relative to personal social ties (micro-level), "community" may also refer to large group affiliations (or macro-level), such as national communities, international communities, and virtual communities. So the correct option is 'assemblage of all the individuals belong to different species occurring in an area'.
C. Ecosphere	An ecosphere is a planetary closed ecological system. In this global ecosystem, the various forms of energy and matter that constitute a given planet interact on a continual basis. The forces of the four Fundamental interactions cause the various forms of matter to settle into identifiable layers. So the correct option is 'interaction between the living organisms and their physical environment'.
D. Ecosphere	The biosphere of the earth or other planet, especially when the interaction between the living and nonliving components is emphasized. So the correct option is 'Part of the earth consisting of all the ecosystems of the world'.
