Resource (biology)

In biology and ecology, a resource is a substance or object in the environment required by an organism for normal growth, maintenance, and reproduction. Resources can be consumed by one organism and, as a result, become unavailable to another organism.^[1]^[2]^[3] For plants key resources are light, nutrients, water, and space to grow. For animals key resources are food, water, and territory.
