Biotic factors are living components of an ecosystem.

A living things must:

•  be made up of one or more cells.

•  need and use energy to carry out life activities.

•  use food (consume).

• let off waste.

•  be adapted (suited) to their environment (surroundings).

•  reproduce organisms of their species

•  grow and develop.

Factors in an Environment

A plant’s environment includes several different factors. Weather is one of those factors. Weather includes the amount of sunlight, the range of temperature, and the amount of yearly precipitation. Soil is another factor. The other plants and animals sharing the environment are still another factor.

Biomes
