4x A(n) __ is a collection of all of the abiotic factors and biotic factors in an entire region. A habitat B ecosystem C community D ecological niche

## Step 1<br />The problem is asking for the term that describes a collection of all the abiotic (non-living) and biotic (living) factors in an entire region. Let's analyze each option:<br /><br />## Step 2<br />A habitat refers to the natural environment in which a particular species of organism lives. It is not a collection of all the abiotic and biotic factors in an entire region.<br /><br />## Step 3<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 /><br />## Step 4<br />A community in biology refers to all the populations that live together and interact in a specific area. It does not include the abiotic factors.<br /><br />## Step 5<br />An ecological niche refers to the role and position a species has in an ecosystem; how it meets its needs for food and shelter, how it survives, and how it reproduces. It does not include all the abiotic and biotic factors in an entire region.<br /><br />## Step 6<br />Based on the above analysis, the term that best fits the description given in the problem is 'ecosystem'.
