The World Of Living
Things around us:
We see many living and non-living things around us.
These things can be divided in different categories. Some of them are living things and the others are non-living things. Some of them are natural while others are made by humans called man-made things.
Living things are alive. They need food, water, and air to live. They reproduce, grow change, and respond to changes in the environment.
Non-Living things are things that were once alive or have never been alive.
Living things and non-living things:
We know, natural things include living things and some non-living things. Things like humans, animals and plants that have life are known as living things. Things like water, mud, stones, etc. have no life and are known as non-living things.
All man-made things are non-living because they do not have life. We know, there are many differences between living and non-living things. Living things have some special features which non-living things do not have.
This world is full of living beings. Scientists use various parameters to differentiate between living and non-living. Following are some difference between living and non-living:
|Living beings respire.
||Respiration is not present in non-living things.
|Living beings take food for nutrition.
||Non-living things do not need nutrition.
|Living beings show locmotion and movement.
||Movement is absent in non-living things. In case of motion in a non-living thing, its is because of power that comes from some external agent.
|Living beings show growth and it comes from inside
||Most of the non-living things do not grow. Growth in some of the non-living things comes from outside.
|All living beings produce their own likes.
||Non-living things cannot produce their copies.
The surrounding in which a living being lives is called its habitat. For example; the pond is the habitat for a frog. Our home is our habitat. A tree is the habitat for a squirrel.
Types of Habitat:
There are two main types of habitat, viz. terrestrial habitat and aquatic habitat.
Terrestrial Habitat: The habitat on land is called terrestrial habitat. The terrestrial habitat can be further categorized as forests, grasslands, coastal, mountain and desert habitats.
Aquatic Habitat: The habitat in water is called aquatic habitat. The aquatic habitat can be further categorized as ocean, rivers, lakes, ponds and swamps.
