Divisions of ecology

Study of the relationships between a single type of organism (specie) and the environment in which it lives (population), studies the adaptations of organisms to their environment

It deals with ecological study of different habitats on planet earth and their effects on the organisms living there.

It studies the relationships between different species belonging to the same group and the environment in which they live, it is the science that studies as a whole the relationships between biological communities and between Earth's ecosystems

It deals with the study of the manner of growth, structure and regulation of population of organisms.

It is a specialty of ecology that deals with the study of the changes that biological populations suffer in terms of size, physical dimensions of their members, age and sex structure and other parameters that define them, as well as the factors that cause these changes and the mechanisms by which they occur.

It is concerned with the ecology of different taxonomic groups of living organisms

It involves population ecology or man and man s relation to the environment, especially man’s effects on the biosphere and the implication of these effects for man.

It deals with the application of ecological concepts to human needs and thus, it includes following applications of ecology: wild-life management, range management, forestry, con­servation, insect control, epidemiology, animal husbandry, aquacultare, agriculture, horticulture, and land use and pollution ecology.

It deals with the ecological study of the processes of soil formation, nutrient cycline energy flow, and productivity.

It deals with energy conservation and its flow in the organisms within the ecosystem. In it thermody­namics has its significant contribution.

Deals with the survival of populations as a result of functional adjustments of organisms with different ecological conditions.

Deals with the study of varia­tions of species based upon their genetic potentialities.

It is probably the most modern branch of ecology, which uses mathematics applied in mathematical and computer models to achieve an understanding of the complex ecological problem.

It is the study of environmental conditions, and life of the past ages

It is a modern subdivision of ecology which is concerned with the development of partially or completely regene­rating ecosystems for supporting life of man during long space flights or during extended exploration of extra-terrestrial environments.
