A biological resource is a substance or object 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.123 For plants key resources are sunshine, nutrients, water, and place to grow. For animals key resources are food, water, and territory.
