There are more than 10,000 species of reptiles. This day helps us understand vast types of their species and their habitats. This day also provides us knowledge about benefits that we get from the world of reptiles.
Living organisms capable of synthesizing food on their own are called as plants. They contain chlorophyll, the green magnesium compound which helps in trapping the energy from sun. This energy runs the process of photosynthesis through which glucose is basically synthesized in leaves and green stems on combining together the atmospheric carbon dioxide and water.
The flow of nutrients in ecosystem takes place in cyclic pathways through food chains, food webs and bio-geo-chemical cycles. Food…
When both the ovaries are fully mature, they alternatively produce ova at the interval of 28 days. Release of ovum into the uterus through the fallopian tube is called as ovulation.
Proper arrangement of resources and techniques to check losses to crops through different factors is called as Crop Protection Management.
Determining male or female form of living organism through sexual reproduction is called as sex determination. Sex determination on a large scale is of two types- environmental, genetic and chromosome based.
The gap between the rich and the poor has increased due to population growth. The rich people are exploiting more resources than poor people. Malnutrition is one of the most common effects of these problems. The poorest people in developing countries do not get adequate calories to develop their health properly.
Urban areas are usually densely populated locations. People migrating from villages towards cities further increase the population burden of cities. Thus urban areas are suffering from serious congestion and traffic problems. Here is a case of Ranchi.
We have damaged ecosystems in the name of development. Wildlife too is facing danger. Our activities have impacted in such ways that animal population has fallen into a serious zone of danger.
A Pesticide is a chemical substance of natural or synthetic origin. It is applied in different forms to kill pests. Pests are living organisms that tend to harm humans, their crops and animals or have a tendency to disturb general household and living conditions. Some organisms can also be applied to kill pests. These organisms are called as biopesticides. On the other hand, pesticides that are synthesized in factories are called as synthetic pesticides.
Different activities may generate waste which may be solid or liquid. The quality of both solid and liquid wastes is increasing and if the wastes are disposed in an uncontrolled manner these may cause adverse impact on public health and environment. Hence these wastes need to be managed efficiently so as to safeguard public health and environment.
