Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.
(j) Biotic Stability: A biotic community has the ability to quickly regain equilibrium after a disturbance in population fluctuation. By studying predation, competition, and symbiosis in a polar ecosystem in. A community of organisms includes all the interacting populations of the species living within a specific area or within a specific habitat.

Some of the major characteristics of a community ecology are as follows: (a) Species Diversity (b) Growth From and structure (c) Dominance (d) Self reliance (e) Relative abundance (f) Trophic structure. Both biotic and abiotic processes can reset the succession process. It consists of populations of different species that live in the same area and interact with one another. They're talking about food webs, networks of feeding relationships. Population vs Community .

Communities are typically studied using a diversity of techniques, including observations of natural history, statistical descriptions of natural patterns, laboratory and field experiments, and mathematical modelling.
Community ecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations. Community Definition.

Name the type of succession in which some life is left after a disturbance. Community ecology focuses on existing species assemblages and recently has begun to integrate history (phylogeny and continental or intercontinental dispersal) to constrain community processes.
