Sources of Irrigation

What is Irrigation? Water is an important input for successful agriculture. Water may be available to crops in the natural course by rainfall or it may be supplied to the agricultural fields artificially by human efforts. The process of supplying water to crops by artificial means such as canals, wells, tube-wells, tanks, etc. from the

Carbon Cycle In Nature

Carbon Cycle: The carbon element is often considered as the basis of all life. Carbon is a basic constituent of living organisms. In fact, carbon is the most essential constituent of all the major organic compounds of the protoplasm (living substance) like carbohydrates, fats, proteins, and nucleic acids. In other words, the carbon element exists

Biogeochemical Cycle

What is Biogeochemical Cycle? The biogeochemical cycle may be defined as the more or less circular path which brings about the circulation of chemicals and elements, including all essential elements from the environment to the organisms and back to the environment. Types of Biogeochemical Cycle: Gaseous Cycles: In which the reservoir is in the atmosphere.

Nitrogen Cycle In Nature

Nitrogen Cycle: The cyclic process by which nitrogen element is circulated continuously through the living and non-living components of the biosphere (like atmosphere, soil, water, plants, and animals) is called the nitrogen cycle in nature. In simple words, the circulation of nitrogen in nature is called the nitrogen cycle. Nitrogen gas of the atmosphere is

Oxygen Cycle In Nature

Oxygen Cycle: Oxygen is the second most abundant element in the earth’s atmosphere. Oxygen forms about 20.9 percent of the atmospheric gases. Oxygen is an essential element for the building up of living organisms and their life processes such as respiration. Oxygen exists in free molecular form as oxygen gas O2. Oxygen is present in

What is Adaptive Radiation?

Buettner-Janusch has defined adaptive radiation as the rapid increase in numbers, and kinds of any evolving group of organisms into several distinctive econiches to which each group is particularly adapted. Thus, adaptive radiation is the spread of a species by way of evolving into progressively distinct types of organisms. From a single ancestral form different

Cloud Formation And Types of Clouds

Cloud Formation And Types of Clouds: Clouds are made up of condensed water droplets, ice particles, or a mixture of both, suspended in the air. Line joining places with the equal degree of cloudiness is called as Isonephs. Formation Of Cloud: Cloud particles grow around a tiny center of solid matter. This dust speck of

Wetland- Types & Importance

What is Wetland? A wetland is an ecosystem in which the land surface is saturated or is covered with standing water for a part of the year. In other words, a wetland is an area of land which is permanently or periodically saturated with water and exists as a distinct ecosystem. Wetlands play many roles
