Introduction - Although population of some animals is also studied, the population of human beings is most extensively studied. Whenever the word population is used, it connotes the human population. Population is one of the most important subjects known for having lar..

Introduction - The Environment influences an organism's life in many ways. It is everything that surrounds an organism and it includes physical and biological components. The physical components of the environment are soil, water, air, light and temperature. These are termed as abiotic co..

Of all the living organisms, only plants are autotrophs i.e., they are capable of synthesizing their own food. Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on plants and other animals for food. Man also being a heterotroph, gets his food fro..

Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced in solution. The behaviour of t..

The term environment refers to the natural elements that make up the earth and surround living organisms, making life processes possible. Soil, water, air, light and temperature are the physical aspects of environment and are known as its 'abiotic' components. All plants and animals coll..

Although population of some animals is also studied, the population of human beings is most extensively studied. Whenever the word population is used, it connotes the human population. Population is one of the most important subjects known for having large scale ramifications on..

Environment is defined as the surroundings in which the organism lives. The environment may be the physical environment, the chemical environment or the biological environment.
