Anything required by an organism to survive, grow, and reproduce
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.
Key resources for plants
Terrestrial plants require particular resources for
photosynthesis and to complete their life cycle of germination, growth, reproduction, and dispersal:[4][5]
