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.〔Ricklefs, R.E. 2005. ''The Economy of Nature, 6th edition''. WH Freeman, USA.〕〔Chapin, F.S. III, H.A. Mooney, M.C. Chapin, and P. Matson. 2011. Principles of terrestrial ecosystem ecology. Springer, New York.〕 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:〔Barbour, M.G.
