Nature restores soil fertility through the following processes: 1) Weathering of rocks. 2) Earthworms and rodents help bring fresh subsoil to the surface by burrowing. 3) Release of minerals by decay of faller leaves, twigs and dead bodies of animals and plants. 4) Biological f..

. Most of the animals are unisexual with an individual only producing either male or female gametes. The male gamete of one individual fertilizes with the female gamete of another individual to produce the zygote. The fertilisation may be external or intern..

In this process semen is collected from a bull of desirable breed and stored at freezing temperature. This semen is injected into the vagina of cows during the period of heat of the animal, for fertilization. This method has many advantages. As many as 3000 cows can be f..

The atmospheric temperature governs the type of biodiversity, fertility of soil, the hydrological cycle and many other abiotic and biotic parameters of our planet. It acts as a resource - in the sense that optimum temperature promotes the production and productivity of many natural resou..

Meiosis - Meiosis is a cell division occurs in reproductive cells (gametes). The male gamete is known as the sperm in animals and the female gamete is known as the ovum (egg). These gametes, after they are formed, have no future unless they unite to form a zygote, which then grows into an..

Felling of forest trees or deforestation decreases the rainfall in that area. Due to less rainfall, new trees will not germinate and grow, production of humus or fertile soil (topsoil) reduces drastically. Soil becomes loose and gets eroded. As the forest area decreases, the animals..

While modern day farmers specialize in one agricultural sector, either dairy or growing potatoes, their predecessors kept a wide array of farm animals and planted many different kinds of field crops. Their farms were remarkably self sufficient, producing eggs, meat, milk, vegetables and g..

Mixed Farming - While modern day farmers specialize in one agricultural sector, either dairy or growing potatoes, their predecessors kept a wide array of farm animals and planted many different kinds of field crops. Their farms were remarkably self sufficient, producing eggs, meat, milk, ..

Air in motion is called wind. Wind velocity can be measured by an Anemometer. It is an important ecological factor of the atmosphere affecting variously the plant life on flat plains, along sea coasts and at high altitudes in mountains. Air generally moves from a region of high pressure to low pres..
