Plants need water to get nutrients from the soil to prepare their food. The plants may wilt and dry up if they do not get water for few days. In the absence of water, plants die and the green character of the plant shall be lost. This will lead to the end of all life from our planet as there will be no oxygen, no food, not enough rain and many other problems that may disturb the ecosystem.

Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food vacuole. Inside the foodvacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm.

Physical change: Those changes in which no new substances are formed are called physical changes. But the properties like state, size, shape and colour changes. If we cut the piece of paper in four parts and again we cut the paper into another four pieces, we cannot join the pieces but the properties are changed.
Chemical Change: Those changes in which new substances are formed are called chemical changes. The properties of new substances formed in a chemical changes are entirely different from those of the original substances. Chemical changes are also called as chemical reactions. The chemical changes are permanent changes which can usually not be reversed to form the original substance. Large amount of energy is absorbed or lost during the process.
The characteristics of chemical changes are as follows:
- One or more new substances are formed in a chemical change.
- A chemical change is a permanent change.
- Sound may be produced in a chemical change.
- A permanent change in colour may take place.
- A gas may be formed during the chemical change.

The removal of fertile top-soil from land by wind or water is called soil erosion. Soil erosion does not occur easily where the land is covered by vegetations. Soil erosion is caused mainly by the large scale cutting down of forest trees and other plants. Large number of trees is cut down for obtaining wood for burning as fuel for building purposes and the manufacture of paper. When the forest trees and other plants are cut down then the top soil gets exposed and becomes loose which causes soil erosion.
The soil erosion could be prevented by preventing large scale cutting down forest trees and by afforestation of large number of plants and trees.
Steps to prevent soil pollution:
- The use of polythene bags should be avoided to prevent soil pollution. It could be done by using bags made of paper, cloth or jute.
- Where ever the plastic objects are used should be sent to factories for recycling to prevent soil pollution.
- The use of pesticides in agriculture should be minimized to avoid soil pollution.
- The use of excessive chemical fertilizers should be avoided to avoid soil pollution.
- The emission of gases like sulphur dioxide and nitrogen oxides from the factories which causes should be controlled as maximum.
