What is Ozone layer? How is it depleted and what are the control measures?
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
Modes of Reproduction
Two organisms- male and female are essential for sexual reproduction. Now let us study some basic methods of reproduction in single organisms.
The Grass Pollinators around us

Our Food, Culture and Biodiversity

Conservation of Wildlife
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
