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.
