Ecology is the study of the interactions between the organism and its abiotic environment. It mainly deals with four levels of biological organization Organism, Populations, Communities and Biomes.
The environment in which we all are living is composed of both abiotic and biotic components. Water, light, Temperature, soil, are the key components of the environment. Biotic components comprise all the living organisms within an ecosystem and it includes plants, animals, birds, insects, bacteria, fungi and more. Abiotic components comprise all the non-living things in an ecosystem and it includes sunlight, temperature atmospheric gases water, and soil
Organisms and Populations are the levels of biological organization. The organism is mainly referred as a living entity which can function on its own and the sum of all the living organisms of the same species living together in a particular geographical area is termed as the population. The size or a growth of population is not static and it keeps on changing along with the time, depending upon the availability of food, predation pressure, temperature, weather and other climatic conditions.
