4x A collection of interacting populations together with all abiotic components in the same area is a(n) A community. x B ecosystem. C population. x 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 a group of living organisms consisting of similar individuals that share similar genes.<br /><br />## Step 3<br />Based on the definitions, the term that best fits the description given in the problem is 'ecosystem'. This is because an ecosystem includes both the living organisms (populations) and the non-living components (abiotic factors) in a specific area.
