NEET Biology Organisms and Environment

 

Ecology is the study of interaction among organisms and between the organisms and their abiotic or physical environment.
The ecology is concerned with the following 4- levels of the biological organization.
1. Organism level
2. Population level
3. Community level
4. Biome level
 
This chapter is dedicated to the first 2- levels of the biological organization, i. e., Organisms and Populations
At ‘organism level’ we will study adaptations of the organisms to their environment. The adaptation may be for their survival or for the process of reproduction. Such an aspect of ecology is called ‘Physiological ecology’.
The seasonal variation of temperature and precipitation (including rain, snow and sleet etc.) are responsible for the formation of major biomes like, Rain forest, Deciduous forest, Desert , Tundra and Sea coast etc. The local variations (Physical or chemical ) in each biome further differentiate various habitats like, polar regions, high mountain tops, rain soaked forests (Meghalaya), Rajasthan deserts, ocean trenches and hot springs etc.

• Each habitat comprises both of abiotic and biotic components .The most important abiotic components (physical or chemical) that characterize various habitats include- temperature, light, water and soil. The biotic component that interact with the organisms include mainly pathogen, parasites, predators and competitors. Over a period of time the organisms evolve through natural selection to optimize their survival and reproduction in a given habitat
