All living things are called organisms. Biodiversity is the short form of Biological Diversity. Biodiversity refers to the wide variety of organisms on Earth.

4
Classification of the organisms is the sorting of organisms (animals or plants) into groups which have similar characteristics. There are 5 major groups: Animals Plants Fungi (mould) Bacteria Simple organisms (unicellular organisms)

AnimalsVertebratesFishBirdsAmphibiansReptilesMammalsInvertebrates
6
Animals with backbone or spinal column. It’s long, strong and flexible. It supports the body, anchors the limbs and protects the spinal cord. Usually large in size.
7
Animals without backbones. Usually small in size. These animals have simple body systems. Insects make up about 90% of all invertebrates.
8
Cold-blooded (poikilotherm) Live in water Bodies are covered with slimy scales Carry out external fertilisation (outside female body) Lay eggs Breathe through gills Examples: pomfret, sea horse, eel, stingray **** Sharks give birth to their young
9
Cold-blooded (poikilotherm) Live in water and on land Bodies are covered with moist skin Carry out external fertilisation (outside female body) Lay eggs Breathe through lungs (adults) gills (young) Examples: frogs, toads, salamander
10
Cold-blooded (poikilotherm) Live on land Bodies are covered with hard dry scales Carry out internal fertilisation (inside female body) Lay eggs Breathe through lungs Examples: lizards, snakes, crocodiles, turtles, tortoise **** Anaconda give birth to their young
11
Warm-blooded (homeotherm) Live on land Bodies are covered with feathers and wings Carry out internal fertilisation (inside female body) Lay eggs Breathe through lungs Examples: duck, pigeon, penguin, eagle, ostriches
12
Warm-blooded (homeotherm) Live on land Bodies are covered with hair or fur Carry out internal fertilisation (inside female body) Give birth to their young and breast feeding Breathe through lungs Examples: humans, cows, bats, cats, porcupine, etc
13
Echidnas lay eggs Whales live in water and give birth Platypus lays eggs Bats have wings Armadillos have scales Anteaters lay eggs
15
Invertebrates account for more than 90% of the species in the animal kingdom. Many of the invertebrates are small I size and they have simple body structures. They cannot grow too big because they do not have a backbone to support their weight.

25
Seeds with one cotyledon. Fibrous roots Leaves with parallel veins Most are herbaceous plants, non-woody stems. Examples: maize, paddy, grass, orchid, sugar cane, banana, etc.
29
Seeds with two cotyledon. Tap roots Leaves with network veins Most are woody stems. Examples: mango tree, durian tree, sunflower, rubber tree, etc.

35
Moss : spores Fern : spores Yeast : budding Conifers : seeds in the cones
36
It has simple stems and tiny leaves No true roots Reproduce through spores produced in capsules at the end of the stalks
37
Moss Liverwort
39
It has stems, leaves and roots It reproduces through spores produced in capsules on the underside of the leaves (fronds) live on land and in moist shady places
40
Bird’s nest fern Staghorn’s fern
42
Have roots, stems and needle-like leaves Do not produce flowers but cones Reproduce through seeds in the cones
43
Pine tree Spruce
44
Unicellular or multicellular organisms Do not have true stems, leaves or roots Live in water or moist places Examples: Chlorella Seaweed Phytoplankton Spirogyra Yeast – reproduce through budding
47
Contributes wealth of resources such as Food Fuels Timber Shelter Spices Clothing Herbs Medicines Maintain carbon, water and oxygen cycles
48
Illegal logging Hunting of wild animals Widespread clearing of forests for housing and urbanisation Overfishing Mining Agricultural activities Building dams
49
Many plants are rich sources of traditional and modern medicines. These are used to treat and prevent diseases.
50
Biodiversity enhances the wealth of gene pools t further increase diversity in the future generations.
51
The diversity of trees and plants enable timber, textile and paper industries to flourish.
52
Plant and animals diversity provides a variety of food.
53
Wetlands and forests provide clean water through repeated filtrations.
54
Plants and trees take in carbon dioxide from the atmosphere and release oxygen during photosynthesis.
55
Many plants and rich sources of traditional and modern medicines. These are used to treat and prevent diseases.
