Trophic Levels : The various steps in a food chain at which the transfer of food (or energy) takes place are called trophic levels. Example A food chain operating in a grassland is given below : Grass -> Insects -> Frog-> Birds In this food chain 1. Grass represents first trophic level. 2 GRead more
Trophic Levels : The various steps in a food chain at which the transfer of food
(or energy) takes place are called trophic levels. Example A food chain operating in a
grassland is given below :
Grass -> Insects -> Frog-> Birds
In this food chain
1. Grass represents first trophic level.
2 Grasshopper represents second trophic level.
3. Frog represents third trophic level.
4 Eagle represents fourth tropic level.
Some approaches towards the conservation of forests are as follows: (a) People should show their participation in saving the forest by protesting against the cutting of trees.

Some approaches towards the conservation of forests are as follows:
(a) People should show their participation in saving the forest by protesting against the
cutting of trees. For example, Chipko Andolan
(b) Planting of trees should be increased. Rate of afforestation must be more than that of
deforestation.
(c) Some people cut precious trees such as Chandan to earn money. Government should
take legal steps to catch these wood smugglers.
(d) Habitants of forests must not be bothered by the forest offcials. Otherwise, this
would result in the clash between tribal people and the government offcials, thereby
enhancing the naxal activities in forests.
We should conserve forests and wildlife to preserve the biodiversity (range of different life-forms) so as to avoid the loss of ecological stability. A large number of tribes are the habitants in and around the forests. If the forests are not conserved, then it may affect these habitants. Without prRead more
We should conserve forests and wildlife to preserve the biodiversity (range of
different life-forms) so as to avoid the loss of ecological stability. A large number of
tribes are the habitants in and around the forests. If the forests are not conserved, then it
may affect these habitants. Without proper management of forest and wildlife, the
quality of soil, the water sources, and even the amount of rainfall may be affected.
Without forest and wildlife, life would become impossible for human beings.
In the case of a long-time perspective in managing our resources, these resources will last for the generations to come. This management ensures uniform distribution among the people. It conserves the natural resources for many years and not just for a few years, as in the case of a short-term perspRead more

Natural resources of the Earth must be distributed among the people in such a way so that no one can be restrained from their share. Forces working against an equitable distribution of resources are: 1. Human greed 2. Corruption 3. Lobby of the rich and powerful people

What are trophic levels? Give an example of a food chain and state the different trophic levels in it.

How would these advantages differ from the advantages of using a longterm perspective in managing our resources?

Why do you think that there should be equitable distribution of resources? What forces would be working against an equitable distribution of our resources?
