Let us write it for you! Two important subdivisions of ecology are recognised by ecologists, these are: It is concerned with the ecology of an individual species and its population.
On the basis of the kind of environment or habitat, ecology has been sub-divided into the following branches: Examples of major communities are: It is a smaller community which is not a self-sustaining unit. It is dependent on other communities for its existence. Structure of a community can be studied by determining the density, frequency and abundance of species. Usually a community has one or more species which occur in large number.
Such species are called dominants and the community is often named after them. The community consists of different groups of plants and animals of different species, may be large and small, may belong to one life from or another but are essentially growing in a uniform environment. This includes study of various life processes respiration, growth, reproduction etc. The recurrence of these important life processes at regular intervals in a year and their manifestation in nature is termed periodicity.
Natural forest communities possess a number of layers or storeys or strata related to the height of plants, for example, tall trees, smaller trees, shrubs and herbaceous layers form the different strata. This phenomenon in a plant community is called stratification. These are marginal zones and are easily recognisable. Usually, in ecotones, the variety of one species is larger than in any of the adjacent communities. A phenomenon of increased variety and intensity of plants at the common junction is called edge-effect and is essentially due to wider range of suitable environmental conditions.
Different species of animals and plants fulfil different functions in the ecological complex. The role of each is spoken of as its ecological niche i. We can also say that ecological niche is a small habitat within a habitat in which only a single species can survive. Communities are not static but progressively change with time in a definite manner. This change of the plant and animal communities in an orderly sequence in an area is called ecological or biotic succession.
Ecological succession finally leads to a stable nature community called climax community. Different kinds of… Causality. Role Of Education in Sustainable Development Sustainable development is that development which will meet the present needs of the community without compromising the ability of future generations to meet their own needs.
