Community ecology focuses on interactions between members of populations of different species. The main difference between population and community is that a population is a group of individuals of a particular species living in a particular ecosystem at a particular time whereas a community is a collection of populations living in a particular ecosystem at a particular time.

Living organisms interact with each other for various reasons including foods, habitats, resources, etc. The main difference between ecology and ecosystem is that ecology is the study of ecosystems whereas ecosystems are units that are formed by the interaction of a community of organisms with the environment. The most basic levels of organization are the species and population levels. (j) Biotic Stability: A biotic community has the ability to quickly regain equi­librium after a disturbance in population fluctuation. The key difference between ecology and ecosystem is that the ecology is the study of ecosystems and the environment while the ecosystem is a unit of ecology that addresses both biotic and abiotic components of a community..

Gross primary production (GPP) is the total energy or nutrients assimilated by an ecological unit (such as an organism, a population, or an entire community). To understand the difference between marine biology and marine ecology, it may be useful to look at a community of organisms. Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment, such as birth and death rates, and by immigration and emigration).. Particular ecologists tend to emphasize certain sorts of techniques and arguments in their research. Return to Ask Questions. Population ecology is the study of populations; specifically, how populations change over time and what environmental factors contribute to that change. The density of mercury is 13.6 g/ml.

Ecology Organisms are grouped as biotic or abiotic, by shape, as well as the distribution and abundance of organisms. Question Date: 2005-02-23: Answer 1: Ecology is a branch of Biology that studies the interrelationships between organisms (plants, animals) and their environment. - Definition & Principles, What Is Ecological Succession? - Definition, Types & Stages, Metapopulation: Definition, Theory & Examples, What is the Biogeochemical Cycle? Ecology is the study of relationships between living organisms (plants, animals, bacteria, humans) and the environment. In Ecology, population refers to individuals of a given single species living in a given place and in a given time. Up Next. Population ecology studies the rise and fall in the number of a species.

The net production of biomass and storage of energy by a community per unit time and area is called community productivity. Physiological ecology refers to affect of environmental conditions on a specific species. Reiter used the word ‘Ecology’ in the year 1865 and Ernst Hackel explained it more profoundly in the year 1869.
