WHAT IS BIODIVERSITY?

Classification of organism


3/31

Vertebrates Aspects Invertebrates

With backbones Presence of

backbones

Without backbones

Main support is

endoskeleton which

consist of bones.

Body support Main support is exoskeleton (such

as hard skin) & fluid pressure

Fish, amphibians,

reptiles, birds &

mammals

Examples Insects, spiders, crabs, prawns.

Worms & molluscs ( such as snails

Diversity in the general

characteristics of livingorganisms.

Animal D has fur while Animal C does not.

Animal C has beak while Animal B does not.

Animal B has fins while Animal A does not.Animal D has hard dry scales why Animal D does not.

Two other ways that I have choosen to classify the 5 animals

are:-

i) Reproductive methods

ii) Body temperature

Vertebrates and Invertebrates

Scientist have so far identified more than 1 million animals. Animals aredivided into two main groups, those with backbones and those without.

Animals with backbones are called vertebrates. Animals without

backbones are called invertebrates

Algae

Sea Alga Chlamidomonas

They live in water and humid soil.

They do not have stems, leaves or roots.

They have chlorophyll.They are unicellular algae (e,g, pleurococus

ad chlamidomonas) and multicellular algae

(e.g. spirogyra and sea weed)


24/31

Fungi

Mushroom Yeast

They live in damp ares.

They do not have leaves, stems, or roots.

They do not have chlorophyll.

They live as parasites or saprophytes.

There are unicellular fungi (e,g, yeast) andmulticellular fungi (e.g. mushroom)


25/31

Mosses

Moss

They live in damp areas.

They have leaves and stems but no root systems.

They have chlorophyll.


26/31

Ferns

Ferns

They live in damp and shady places.

They have stem and leaf systems.They have chlorophyll.

They reproduce by spores.

Introduction

From afar, rainforests look green, mysterious, quiet

and peaceful. However, this is afar from the truth.

They are actually made up of rich wildlife full of

activity. Our rainforest boast of millions of species of

flora and fauna which are unique and not found

anywhere else in world.

Objective

By the end of this chapter, we should be able to

Understand the variety of living organisms and their

classification.
