Population Ecology

Population Ecology The word population is derived from latin word 'populus' which means people. Organism in nature rarely grow as separate from each other. Each species in an ecosystem exist as a population. Population: Population is the group of organisms of the same species that live in a particular geographic region at the same time with capability of interbreeding. Population ecology defined how these population interact with the environment. It deal with the pattern in the abundance and distribution of organisms that produce this. There are two types of population. A. Unitary population B. Modular population. A. Unitary population: In unitary population each individuals is originated from zygote ( The product of fertilization of male and female gamete ) and growth of such individuals is determinant and predictable. Example: Mammals, Birds, Amphibian, Insects. B. Modular population: In case of modular population, zygote develops into ...
