4x A collection of interacting populations together with all abiotic components in the same area is a(n) A community. B ecosystem. 4x C population. 4x D species.

## Step 1<br />The problem is asking us to identify the term that best describes a collection of interacting populations together with all abiotic components in the same area. The options provided are: A community, B ecosystem, C population, and D species.<br /><br />## Step 2<br />Let's define each term:<br />- A community refers to all the populations that live together in a specific area.<br />- An ecosystem includes all the living things (plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments (weather, earth, sun, soil, climate, atmosphere).<br />- A population is a summation of all the organisms of the same group or species, which live in a particular geographical area.<br />- A species is the most precise level of classification of living things. It is the basic unit of classification and a taxonomic rank.<br /><br />## Step 3<br />Given the definitions, the term that best fits the description in the problem is 'ecosystem'. This is because an ecosystem includes both the living organisms (biotic components) and the non-living components (abiotic components) in a specific area.
