dependence of man on environment

The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating laye..

Introduction - Environment is defined as the surroundings in which the organism lives. The environment may be the physical environment, the chemical environment or the biological environment. Thus, the environment has two components - abio..

Conservation is defined as judicious use to avoid wastage of materials and degradation of environment. Conservation of environment involves the conservation of the natural resources. The non-renewable resources have to be conserved as they cannot be replenished. The reserves of ..

Summary - Environment is defined as the surroundings in which the organism lives. It has two components - abiotic and biotic. The abiotic environment includes the air (atmosphere), water (hydrosphere) and land (lithosphere). The biotic environment includes the plants, ..

Human Dependence on Plants and Animals for Food - Of all the living organisms, only plants are autotrophs i.e., they are capable of synthesizing their own food. Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on plants and other anima..

As mentioned earlier man's intervention is causing drastic changes in the environmental systems of earth and disturbing its ecological balance. This disturbance gets compounded with the problem of population explosion in the world especially the developing countries. The rate per annum at..

Global Warming - The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back int..

Of all the living organisms, only plants are autotrophs i.e., they are capable of synthesizing their own food. Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on plants and other animals for food. Man also being a heterotroph, gets hi..

Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on plants and other animals for food. Man also being a heterotroph, gets his food from plants as well as animal..
