There are three phases of development of technology- invention, innovation and diffusion. The invention is a process which incorporates wide range of ideas, material things, and human behaviour in new systematic ways.
A population is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed. Each population has a unique physical distribution in time and space. It may contain individuals of different ages, and its size (density) is likely to change over time. It grows or shrinks according to the reproductive success of its members.
An area or structure that protects animals from adverse conditions is called an animal shelter. Different kinds of animals need different types of shelters. Different kinds of animals and their shelters are mentioned here.
Kinds of animals and their shelters
Animals can be classified into terrestrial, arboreal, aquatic and amphibians.
Terrestrial Animals
Land animals are called as terrestrial animals. Some of these animals like lion, tiger, bears and bats live in rock caves. Illustration
Snakes live in ground, under rocks and in abandoned ant hills. Some snakes live insid
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
Anything from which we can derive energy is called as a source of energy. Since all the life processes need energy, energy is most important for our survival. Our body derives energy from the food we eat. Thus, the food we eat is the source of energy for our body. But this is not the whole story. We need energy for our growth and economic development as well.
The application of scientific knowledge for practical purposes, especially in industry, is called as technology.
There are many different types of technologies or technological models- such as Low-tech, Hi-tech, alternative, intermediate, appropriate, blended, hard, and soft technologies.
Land management is the process of managing the use and development of land resources in rural and urban areas.
A group of individuals of a particular species occupying a particular area at specific time is called as population.
A group of individuals of a particular species occupying a particular area at specific time is called as population. A species is a group of similar type of organisms that can interbreed under natural conditions. The interbreeding organisms of a species produce new organisms and finally result into the growth of population. This is true for all the life forms including human beings.
Rains in Nepal have always been responsible for floods in Bihar. Most of the rivers flowing through Bihar have their origins in Nepal. Since last three days Nepal is experiencing continuous rainfall. This is why villages in Bihar are being seriously flooded. What can be done?
Landslides are very common in rainy season. Rains caused serious conditions during previous some weeks this year in many villages of Maharashtra. Many of these villages that were located in the laps of mountains vanished within no time.
