2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.
b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.

Answer:
All the things expect enegry are recycled.
Explanation:
- When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
- The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.
But incase of enegry it cannot be recycled but frequently transfered from one form to another form.
