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

Force characteristics are related to variations in motivation, persistence and temperament. Bronfenbrenner notes that even when children have equivalent access to resources, their developmental courses may differ as a function of characteristics such as drive to succeed and persistence in the face of hardship.
where N j is the density of species j, R is the density of the resource, a is the rate at which species j eats the resource, d is species js death rate, and r is the rate at which resources grow when not consumed. It is easy to show that when species j is at equilibrium by itself (i.e., dN j /dt = 0), that the equilibrium resource density, R* j, is
