Ecosystems

Evelyn, Aria, and Sophia went on a field trip to a forest. They observed various living organisms and nonliving components interacting with each other. Based on this, how would they define an ecosystem?

• An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment.

• An ecosystem is a term used to describe the process of photosynthesis in plants.

• An ecosystem is a type of computer software used for managing databases.

• An ecosystem is a group of people working together towards a common goal.
