The various links or steps in a food chain at which the transfer of food and energy takes place are called trophic levels.
The producers form the first trophic level as they manufacture food. The primary consumers form the second trophic level, the secondary consumers form the third, and the tertiary consumers form the fourth trophic level.
Grass is the producer which is eaten by the grasshopper known as primary consumer. Then the grasshopper is eaten by shrew, secondary consumer and lastly shrew eaten up by owl, tertiary consumer.
Natural resources of the Earth must be distributed among the people uniformly so that each and every one gets his share of the resource. Human greed, corruption, and the lobby of the rich and powerful are the forces working against an equitable distribution of resources.

A long term perspective in managing our resources would always be better than a short term perspective. A long term perspective helps us in protecting our environment and also in conserving our natural resources. This is an integral part of sustainable development.

A long term perspective in managing our resources would always be better than a short term perspective. A long term perspective helps us in protecting our environment and also in conserving our natural resources. This is an integral part of sustainable development. This will help us in ensuring that the future generations also get to enjoy the bounty of nature.
The exploitation of resources with short-term aims means the consumption of resources in such a way that they can help in achieving the short term goals without the concern for future generations. The advantages of exploiting resources with short term aims will be: (a) Industrial growth will be fastRead more
The exploitation of resources with short-term aims means the consumption of resources in such a way that they can help in achieving the short term goals without the concern for future generations. The advantages of exploiting resources with short term aims will be:
(a) Industrial growth will be fast.
(b) The percentage of gains will be much higher.
Add few drops of solution from all three test tubes on the red litmus paper separately. The solution which turns red litmus to blue contains basic solution. Use this blue litmus paper to test the solutions in other two test tubes. The solution from the test tube which turns blue litmus paper to redRead more

Use this blue litmus paper to test the solutions in other two test tubes. The solution from the test tube which turns blue litmus paper to red will be the acidic solution and solution of the test tube which do not change either red or blue litmus paper contain water.

Natural resources of the Earth must be distributed among the people uniformly so that each and every one gets his share of the resource. Human greed, corruption, and the lobby of the rich and powerful are the forces working against an equitable distribution of resources.
