WHAT HAPPENS IT DOES NOT RAIN FOR LONG PERIOD

Sometimes so happens that does not rain in region for a year or more. This leads shortage of water that region causing everywhere. environment drought. So, can say that if does not rain in region for long time causes drought sookha). Drought is period without rains leading to severe shortage of water in the region. happens follows.

The soil in the fields is normally moist because it has water in it. The soil continues to lose water by rporation and transpiration. The water lost by soil is usually made up by rains. If, however, it does not rain at all (or the rainfall is very low) for a long period, the o of water from the soil is not made up and hence the soil becomes dry (see Figure 14). Due to lack of rains, the water level in the lakes and ponds also goes down and some of them may even dry up completely. In the absence of rains, no water seeps into the ground and hence the level of groundwater in wells, etc., falls drastically. Due to this the groundwater also becomes scarce. In this way, a prolonged period of no rains (or very low rains) causes all round shortage of water leading to drought. Thus, the lack of rains for long periods may cause drought.

This picture shows the extremely dry cracked set in a field camed by the lack of rains.

The people living in areas having drought conditions face many difficulties in leading a normal life. Some of the ove long period problems faced by the people because of drought in an area are as follows:

In drought conditions, the soil does not have sufficient moisture (or water) to grow crops well. Since the crop plants do not grow well, drought leads to severe shortage of food for the people in that region. (ii) In drought conditions, the vegetation such as grass and other fodder does not grow well and leads to shortage of fodder for the domestic animals (like cows and buffaloes). () Due to shortage of food and fodder, many people living in drought affected areas even migrate to other places alongwith their domestic animals in search of food and fodder. Some people and domestic animals may even die of starvation.

What are life process?

WHAT ARE LIFE PROCESSES? The maintenance functions of living organisms must go on even when they are not doing anything particular. Even when we are just sitting in class even if we are just asleep, this maintenance job has to go on The processes which together perform this maintenance job an We processes . Since these maintenance processes are needed to prevent damage and break-down energy is needed for them. This energy comes from outside the body of the mdhadual organism. So there must be a process to transfer a source of energy from outside the body of the organism which we call food, to the inside, a process we commonly call nutrition If the body size of the organisins is to grow, additional raw material wit also be needed from outside. Since life on earth depends on carbon- based molecules most of these food sources are also carbon-based Depending on the complexity of these carbon sources, different organisms can then use different kinds of nutritional processes The outside sourc...

Nutrition in human being?

Nutrition in Human Beings The alimentary canal is basically a long tube extending from the mouth to the anus. we can see that the tube has different parts. Various regions are specialised to perform different functions. What happens to the food once it enters our body? We shall discuss this process here. We eat various types of food which has to pass through the same digestive tract, Naturally the food has to be processed to generate particles which are small and of the same texture. This is achieved by crushing the food with our teeth, Since the lining of the canal is soft, the food is also wetted to make its passage smooth. When we eat something we like, our mouth waters. This is actually not only water..but a fluid called saliva secreted by the salivary glands. Another aspect of the food we ingest is its complex nature. If it is to be absorbed from the alimentary canal, it has to be broken into smaller molecules. This is done with the help of biological catalysts called enzyme...

Adaptation in lion & adaptation in deer

A large area of land covered mainly with trees and plants is called alaust And a large area of grass covered land used for grazing is called grassland There are few trees or places for animals to hide gland habitats. Due to this speal is important for the animals which live in grassland habitats (so they can nits away from their enemies) For most common purposes, however, the wrous forest and and are used in the same sense. The forest (or grassland) is a habitat Many animals such as lon som elephants deer, en live in forest habitats. There are many features of a lion, a deck, other animals and plant which help them to survive in the forest habitat. The adaptations in lion and deer to the forest habitat are described below. Adaptation of lion The lion is a camivorous animal which eats only the meat (or flesh) of oder animals. The lion lives in a forest habitat The adapted to the forest habitat in the following ways: 1.The lion is a strong, fast and agile animal which can hunt and ...
