Question

An ecosystem is not a self-sufficient unit.

• A. True
• B. False

Answer 1

The correct option is B False

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. The Sun is the source of energy in most ecosystems. Energy is transferred from the Sun to plants that make their own food. The stored energy in plants is transferred to animals that eat the plants. When organisms die, their bodies decompose, or break down. The materials needed by organisms in an ecosystem are recycled, or used over again.

So the given statement is false.
