Answer 1

An ecosystem is a biologic community and components of the physical environment with which the community interacts.

Explanation:

An ecosystem is the totality of interactions between living (biotic) and non-living (abiotic) components, capable of independent existence. It is a self-sufficient unit with cyclic exchange of materials between living beings and the environment, requiring a constant input of energy, primarily from sunlight captured by green plants through photosynthesis.
