Answer 1

The basic level of an ecosystem is the **individual organism**. This is the smallest unit in the ecological hierarchy, representing a single living entity. From there, multiple individual organisms can form a **population**, which is made up of members of the same species. Several populations interact within a **community**, and all communities along with their physical environment make up an **ecosystem**.
