ANATOMY

Detailed explanation-1: -What Do Organisms Compete For? Organisms compete for the resources they need to survive-air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).

Detailed explanation-2: -Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other. Competition occurs above-and belowground.

Detailed explanation-3: -Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area. This type of competition is a basic factor in natural selection. It leads to the evolution of better adaptations within a species.

Detailed explanation-4: -Animals compete for air, food, shelter, water, and space. Plants also compete with each other for the resources they need, including air, water, sunlight, and space. These interactions within an ecosystem help keep the populations of various organisms in balance and are necessary to keep an ecosystem healthy.
