MAN AND NATURAL ENVIRONMENT

—Environment means the surrounding conditions that effects the lifestyle of living things.—It includes biotic and abiotic components.—Our surroundings includes natural and man made things.—Human life gets affected by the environment and hence we find differences in the human life of different regions.

 Natural environment—All components which come into existence naturally are included in natural environment.—The land-forms on the earth, the climate, soils, minerals, sunlight etc are components of our natural environment.

 CULTURAL ENVIRONMENT—In order to enrich his life man has used many natural resources and in this process he has brought many changes in natural environment. Human settlements, roads, buildings, dams etc have developed through this.

Interactions in environment—THERE ARE MANY INTERACTIONS BETWEEN BIOTIC [LIVING] AND ABIOTIC [NON LIVING] COMPONENTS.—ALL THE BIOTIC COMPONENTS DEPEND ON EACH OTHER.WE BREATHE AIR THAT MEANS THERE IS AN INTERACTION BETWEEN US[LIVING] AND THE AIR [NON LIVING]—PLANTS MAKE PRODUCE THEIR FOOD USING SOLAR ENERGY.THAT MEANS THERE IS AN INTERACTION BETWEEN ABIOTIC AND BIOTIC COMPONENTS.

ECOSYSTEM—A closely related group bio-community  and the  surrounding environment. On which the life of the community depends together form an eco-system together form an eco-system.—All the natural regions wherein interactions takes place between abiotic and biotic components are called ecosystem.

—PRIMARY CONSUMER..—The plants are the producers whereas the hair that uses only green plants as its food is called primary consumer…

—SECONDARY CONSUMER…—The hare becomes food for a snake hence carnivores animals like snakes are called secondary consumers…

—TERTIARY CONSUMERS…..

—The snake becomes food for an eagle hence eagle is called tertiary consumer. Eagle is in highest consumer in the food chain……..

FOOD PYRAMID—SOME OF THE ENERGY GETS LOST AT EACH LEVEL. DUE TO THIS WHILE MOVING FROM PRODUCERS TO LOSS DIFFERENT TYPES OF CONSUMERS,THERE IS A DECREASE IN ENERGY.—IF ONE ATTEMPTS DIAGRAMMATIC REPRESENTATION OF THIS PROCESS THIS DIAGRAM APPEARS LIKE A PYRAMID.THIS IS CALLED FOOD CHAIN.
