Biodiversity, Its Concept, Values, Loss, and Causes of Loss
An association of all the plants at a particular place is called a Plant Community and the association of all the animals at the same place is called an Animal Community.

Members of a community not only interact with the members of other communities, they interact with the members of their community and with the physical environment around them, as well.

Loss of Energy in the Food –Chain
About 1000J radiant energy comes to the earth from the sun. Out of this, only 10% of the total energy is used up by green plants in the process of Photosynthesis. Remaining 990J of energy escapes away into the atmosphere. 10J of energy is stored in the form of chemical energy in starch and sugars.
Problem of Urban Congestion
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.
How to manage our Natural Resources
Human activities have never been friendly to environment. The remains of Mohenjo-Daro and Harappa signify that the civilization ended due to desertification which might had been caused by large scale deforestation. Still today impacts of such human activities have started appearing. Hence it is essential that we manage our natural resources properly.
What is Ecosystem? What are its components?
The environment of our earth has a number of life zones that support birth and development of all types of organisms.
All the life zones of the earth are collectively called as Biosphere.
The biosphere vertically extends into the atmosphere up to about 10 km and downwards into the oceans up to a depth of about6.9 km.
Types of species
Species can be classified in many different ways. One species classification system may categorise species into Typological, evolutionary, and phylogenetic species.
