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.[1][2][3] For plants key resources are sunshine, nutrients, water, and place to grow. For animals key resources are food, water, and territory.

Key resources for plants[edit]

Terrestrial plants require particular resources for photosynthesis and to complete their life cycle of germination, growth, reproduction, and dispersal:[4][5]

Key resources for animals[edit]

Animals resources particular resources for metabolism and to complete their life cycle of gestation, birth, growth, and reproduction:[6]

Resources and biological processes[edit]

Resource availability plays a central role in ecological processes:
