Q: In biology, what is required for ecosystems to survive?


Read this paragraph and choose the correct option from the provided answers:

In biology, energy is required for ecosystems to survive, as all living organisms need energy. Within an organism, energy is needed for growth and development of a biological cell or an organelle within that cell. Energy is also needed for all biochemical reactions within that cell. Therefore, energy is stored within cells in the chemical bonds of substances such as carbohydrates (including sugars), lipids, and proteins. This energy is released during aerobic respiration.

 Choices:

- helium

- space

- minerals

A:
energy
