Describe in your own words what you understand by the term `ecology’.

Ecology refers to the complex network of biological and physical systems and processes between the biotic and abiotic components of environment. It is responsible for the type of environment around living beings. Humans are also a constituent of ecology. Various physical features like mountains, rivers, plains and oceans, each with their unique flora and fauna, form their own ecology. The ecology of a place is affected by the interaction between its geography and hydrology. The flora and fauna of a particular region adapt themselves according to its ecology, in order to survive. Ecology of a place has an impact on the human living conditions and the lifestyle, food, clothing, occupation and culture of the people of that place.
