Living things

INTRODUCTION:
(1) There are many things found around us. Some of them are living things
like animals and plants and some are non-living things like book, pen, ball,
river, mountain etc.
(2) Plants and animals appear to be entirely different from each other but
they posses remarkable similarities between them.
(3) Let us study these similarities among living things and differences
between Jiving and non-living things.

ERISTICS OF LIVING THING
(1) There are seven characteristics which differentiate living things from
on-living things these characteristics of living things are as follow:
(1) Movement (2) Nutrition (3) growrh 4 excretion
(5) Respiration (6) Reproduction (7) Sensitivity

1) MOVEMENT:
(1) Living things can move from one place to other by themselves.

(2) Man and other footed animals can walk with the help of their legs.
(3) Birds can fly with their help of wings.
(4) Some animals can creep such an snake.

movement. If you touch the finger on mimosa leaves (touch me-not), close
its leaflets and when took the finger back, they open again after sometimes.
Non-living things move only when an external force is applied. A ball and
stone can change their position only when they are thrown by you

NUTRITION:

soil and carbon dioxide from air in the presence of sunlight. The proces
