Conservation of Plants and Animals Test - 7

The diversity of genes, species and ecosystems of a region is called biodiversity.

Uncontrolled deforestation leads to destruction of habitats, soil erosion, flash floods, increase of carbon dioxide in the air and global warming.

Drought which is caused due to lack of rains results in decreased food production.

Biosphere is the name given to the region that include all living organisms and all life supporting regions of the earth.

By recycling resources, we can prevent overexploitation of resources and conserve the resources and in turn conserve the environment.

The non-living or abiotic components of an ecosystem are air, water, temperature, soil etc.

Excess timber logging results in deforestation which causes flooding soil erosion, etc. Selective logging (i.e. the logging of only matured trees should be practised). Reforestation helps in minimizing the effect mismanagement.

Conservation involves keeping the natural environment in its balanced state. Preservation involves keeping some of the earth's resources for future generations.

The introduction of exotic species into an area disturbs the natural ecology balance. They compete with the native species for nutrients, shelter and spread new diseases.

Forests stop soil erosion, provide shelter and thus prevent floods. Forests provide us with oxygen and rainfall.
