Rainwater which falls on roofs and terraces of buildings can be collected through pipes and stored in underground tanks or can be allowed to percolate into the soil and used to recharge the groundwater table. This is called water harvesting or rainwater harvesting. The main aim of rainwater harvesting is to check the runoff water.

Rainwater Harvesting
The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the groundwater, is called rainwater harvesting.
The two main techniques of rainwater harvesting are:
1) Collection and storage of rainwater in tanks for future use when there is scarcity of water, and
2) To make rainwater percolate into the ground more efficiently by constructing percolation pits and recharge wells so as to recharge (or replenish) groundwater.
Rainwater harvesting can be done in two ways:
1) Rooftop rainwater harvesting, and
2) Rainwater harvesting from open spaces around buildings

Can you think why Sunita’s hair was standing?
Ans. We know that on earth, our hair remain in downwards portion due to earth’s gravitational force. But in space, there is no such gravitational force. That is why Sunita’s hair were standing.

The sequential process of eating and being eaten is called a food chain.
Grass → Grasshopper → Snake → Hawk → Fungi
- All food chains begin with green plants or producers. Thus, the plants or producers constitute the first trophic level. Example: Grass
- The herbivores or primary consumers that feed on plants constitute the second trophic level. Example: Grasshopper
- The herbivores are next fed upon by the carnivores or secondary consumers. They constitute the third trophic level. Example: Snake
- Finally, the large carnivores, also called the top carnivores or tertiary consumers, form the fourth trophic level. Example: Hawk
- The large carnivores die and form the feed of decomposers. The decomposers feed on these dead animals and plants. Example: Fungi
- There is a transfer of food from one organism to the other forming a chain.
