Population Control
Through different means – natural and unnatural the process of keeping in a limit the growth of population is called as Population Control. It is essential for the welfare of human families. This is the reason why its name has been changed to the Family Welfare.
Darwin Day
Darwin published his book “On the Origin of Species” on 24 November 1859. The aim of Darwin Day inspires to fulfil the academic curiosities. It demands to search the truth in scientific ways.
What is Global Warming and how is it linked to Green House Effect?
Human activities of pollution are modifying the natural process of green house effect. The advent of the Industrial Revolution in the 1700s boosted up the activities of burning of fossil fuels like coal, oil and natural gas which released lots of heat absorbing gases into the atmosphere.
Positive and Negative Interdependence among Organisms in Ecosystems
Interdependence between two species through which individuals of either one or both species benefit is called positive interdependence. The benefits to the individual of any species through this relationship may be continuous or transitory, obligate or facultative. Both partners in this type of relationship may be in close contact; one may be inside some specific area or attached to the surface of the other’s body. Positive interdependence is divided into three major types: mutualism, Commensalism, and proto-cooperation.
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.
Toucan- a cute and cruel but friendly and smart bird
Toucan is a cute and friendly bird with a small rounded tail and a long, red and amazing bill. It belongs to family Ramphastidae of zoological order Piciformes belonging to the genus Ramphastos.
There are 37 species in Ramphastidae and the largest birds are known as Toco toucan. The bird about which we are going to talk about right now is the Toucan – yes, the Ramphastos aerial. You might have seen some famous TV serials with Toucan as one of the leading characters on the National Geographic; or some famous children’s films with Toucan as here- like Rio-.
Terrestrial Ecosystems and Their Components
The biosphere is itself a vast ecosystem which incorporates all the small ecosystems. But, the biosphere may have different types of physical conditions, communities of plants and animals, and climatic conditions in its different zones.
Our Natural Resources- Let’s Conserve
The conservation of environment implies the sustainable use as well as management of natural resources including wildlife, water, air, and soils of the earth.
Biotic Components of Ecosystem
Living beings in environment like animals and plants constitute more than half of the environment in the biosphere. All of these need to be conserved.
Eat Okra to remain Fit and Fine
Bhindi in Hindi and Okra in English has been an integral part of the Indian vegetable since very long.
Processes of Life
All those processes that maintain the body of an organism collectively are called as life processes. These processes principally include Nutrition, Respiration, Internal Transport, and Excretion. Some other processes of life like control and coordination, Reproduction, Heredity and Evolution etc. are essentially found in living beings but they are not directly related to processes of life. Hence, these may or may not be regarded as life processes
