Explanation:

To order the levels of organization from smallest to largest, we analyze each term:

1. A living thing: This is an individual organism, the most basic unit.
2. A group of the same species living in an area: This is a population (same species, same area).
3. All species living in an area: This is a community (multiple populations in an area).
4. All living and nonliving things in an area: This is an ecosystem (community + abiotic factors).

Answer:

1. A living thing
2. A group of the same species living in an area
3. All species living in an area
4. All living and nonliving things in an area
