Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms that include biotic and abiotic components of their environment.

Ecology: Basic Terms (in Hindi)

Four Basic Components of an Ecosystem

Abiotic Components. The abiotic components of an ecosystem are all of the nonliving elements. ...

Producers at the Base. Producers are the living organisms in the ecosystem that take in energy from sunlight and use it to transform carbon dioxide and oxygen into sugars. ...

Consumers in the Chain. ...

Decomposers and Nutrient Cycling.

Componen of Ecosystem (in Hindi)

Course Overview (in Hindi)

Effects of Temperature of Ecological Factors. Temperature has direct effect on the metabolic activity of the organisms. ... Initially with the increase in temperature, enzymatic activities also increase; thereby increase the rate of metabolism.

Effect of Temperature (in Hindi)

Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.

Abiotic Factors: Atmosphere, Soil (in Hindi)

A lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Lake ecosystems are a prime example of lentic ecosystems. Lentic refers to stationary or relatively still water, from the Latin lentus, which means sluggish.

Ecosystem of Lake, ocean, river

Energy Flow in Ecosystem. Energy moves life. The cycle of energy is based on the flow ofenergy through different trophic levels in anecosystem. Our ecosystem is maintained by the cycling energy and nutrients obtained from different external sources.

Energy flow and Productivity

Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. It is the study of how the population sizes of species change over time and space.

Population Ecology (Part-1)

Population Ecology (Part-2)

Ecological succession is the process of change in the species structure of an ecological community over time. ... It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat.

Ecology is basically the scientific study of Interactions of organisms, biotic as well as abiotic, with one another.There are numerous concepts that needs special attention to understand this very fascinating domain. This course is all about it!

(Hindi) Very important concepts of Ecology

This course includes Ecological Concepts, rules and principles that are very significant in understanding Ecology. Basically, these recognising principles at work helps to determine important features about species in different geographical areas.

After completing this course you will be able to know about different growth patterns, curves and population Pyramids of organisms, information discussed here will be helpful to you in clarifying of different ecological principles & facts in detail.
