Jump to: navigation, search

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.

Key resources for plants

Terrestrial plants require particular resources for photosynthesis and to complete their life cycle of germination, growth, reproduction, and dispersal:45

Key resources for animals

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

Resources and biological processes

Resource availability plays a central role in ecological processes:
