breathe out carbon dioxide (CO2).

Two kinds of breathing process. Anaerobic andaerobic respirations. Anaerobic respiration is

We react to touch, light, heat, cold and sound,as do other living things.

produce kittens and pigeons lay eggs. Plants also reproduce.

Many make seeds which can germinate and grow into newplants.

Organisms can reproduce either sexually or asexually, but some

can reproduce in both ways.

the mating phenomenon is also known as fertilization. In this

phenomenon male and female gametes meet.

in plants the result of its sexual reproduction is seeds, in

animals it is eggs or fetus.
