What is BiodiversityThey are many different kinds of organism.

Scientist estimate that there is about 10 to 100million kind of organism living on earth. Ofthese, only less than 2 million kind have been

identified. The rest are yet to be discovered.

Biodiversity is a wide variety of organisms onearth. We can see this diversity everywheresuch as at local parks, forests, mountaintops

and even deep down in the ocean.

Classification ofOrganismsSorting organisms into groups is called

classification. As new organisms arediscovered, new characteristics are used inclassifying these organisms. As a result, over

the years, the classification system has alsogone through some changes.

In classifications system used today, organismsare classified into 5 major groups called

kingdoms. They are animals, plants, fungi,bacteria and very simple organisms


7/32

Classification Of PlantsThere is a large variety of plants living in

different habitat.

Scientist have classified them into group

because it is difficult to study them one byone.

Plants belonging to the same classhave thesame characteristic.

There are classified like these

MonocotyledonsThey have fibrous roots.

Their leaves have parallel veins.

They are mostly herbaceous plants do not

have woody stems.Example:

DicotyledonsThey have tap roots.

Their leaves have network of veins.

They are trees, shrubs or herbaceous

plants.

Classification Of Animals


14/32

AmphibiansAmphibians are cool-blooded that can live both

on land and water.

Most amphibians adults live on land.

They return to the water only to lay eggs.

The eggs are fertilised outside the femalesbody (external fertilisation).

The young amphibians live in water andbreathe through their gills.

The adults breathe with their lungs when onland and through their skin in water

Amphibians

FishFish have body that are well adapted for life

underwater.

Their skin is covered with hard and slimy scales forprotection.

They have fins and tails to swim.They absorbed dissolved o2 in the water through

their gills.

Most of them lay eggs that are fertilised outsidetheir bodies.

Fish are cold-blooded animals.Their body temperature changes with their

surrounding temperature.

BirdsBirds are the only animals with feathers.

They have beaks and wings but not all of themcan fly

They breathe with their lungs. They are warm-blooded animals

Their body temperature remains constant anddoes not changes with the environment.

Their eggs, which are fertilised internally havehard shells are laid in their nests

Birds


20/32

MammalsMammals are warm-blooded animals whose

bodies are covered with hair and fur.Their eggs are fertilised internally and their

young develop inside the female body.

All mammals except the duck-billed platypusand the spiny anteater, give birth to liveyoung.Their young feet on milk from the mothers

mammary glands.

Mammals breathe with their lungs.This include those living in the water dolphinand whales.

Mammals

ReptilesMany reptiles live on land

All reptiles have hard try scales to protecttheir bodies

They breathe with their lungs

They are cold-blooded animalsReptiles eggs are fertilised inside the

female body

The eggs have tough, leathery shells toprevent them from dying out

Is It Important To Maintain

BiodiversitySource of food- We eat a variety of plants and animals.

Different foods provides us with different materials

Source of materials-We make houses, furniture,handicrafts from various plants

Source of medicine-Both modern and traditional medicinesmake use of extracts from various plants and animals totreat and prevent diseases

Clean water-Forest and wetlands filter again and againmaking it clean for us to drink, bathe and grow crops

Air to breathe-Plants take in carbon dioxide from the airand release oxygen into it
