Question

C. Give two examples.<br />1. Biotic components<br />2. Chemical changes<br />3. Habitats<br />4. Methods of vegetative propagation<br />5. Types of joints​

Answer 1

Biotic components are living things like plants and animals.

Chemical changes are the changes in which a substance completely loses its properties and a new substance is formed. Eg:- rusting of iron, anodizing of aluminium, burning of paper.

A habitat is the type of natural environment in which a particular species of organism lives. Eg: Gir forests, Sunderbans etc.

Some methods of vegetative propagation are Grafting and layering and tissue culture.

There are three main types of joints:- Fibrous (immovable), Cartilaginous (partially movable) and the Synovial (freely movable) joint.
