Population and Its Characteristics - Population is the next level in ecological hierarchy the word population has its origin in the Latin word populus meaning 'people'. In ecology, population is defined as the total number of all individua..

Individuals living in the same area are referred as local populations. They all experience similar ecological processess at a particular stage of the life cycle. Similar populations of a species occupying different geographical areas are called sister populationsh..

Interrelationship of Population, Environment and Development - As mentioned earlier man's intervention is causing drastic changes in the environmental systems of earth and disturbing its ecological balance. This disturbance gets compounded with the problem of population..

Summary - Smallest unit of ecological hierarchy is the organism, while smallest and basic unit of taxonomic hierarchy is species. A group of individuals, having similar structural and functional characters, capable of potential interbreeding is termed as species. In nature all apecies exh..

. Terrestrial ecology is further subdivided into forest ecology, grassland ecology, cropland ecology and desert ecology. Demecology is that branch of biology which deals with the ecology of populations. Modern ecology i..

a) Local species diversity is directly related to the efficiency with which the predators prevent the monopolization of an environmental area by any species. b) Predation keeps the prey population under check, so as to maintain an ecological balance. c) Weak and less efficient ..
