LIVING ORGANISMS AND THEIR SURROUNDINGS
CLASS VI
2
ORGANISM-LIVING CREATURE
LIVING ORGANISMS ARE FOUND EVERYWHERE ON EARTH
3
HABITAT THE NATURAL LIVING PLACE OF AN ORGANISM IS ITS HABITAT.
AN ORGANISM DEPENDS ON ITS HABITAT FOR FOOD, WATER, AIR, SHELTER etc. SEVERAL KINDS OF ORGANISMS ARE FOUND IN A HABITAT.
4
ADAPTATION THE PRESENCE OF SPECIAL FEATURES IN OR CERTAIN HABITS WHICH ENABLE A PLANT OR AN ANIMAL TO LIVE IN ITS SURROUNDINGS IS CALLED ITS ADAPTATION.
5
I. TERRESTRIAL HABITAT IF THE HABITAT IS LAND, IT IS CALLED TERRESTRIAL HABITAT. EXAMPLES-DESERT,FOREST, GRASSLAND, MOUNTAINS etc.
6
1.DESERT
7
DESERT PLANTS AGAVE CACTUS DATE PALM
8
DESERT PLANTS ADAPTATIONS OF DESERT PLANTS
1. LEAVES ARE ABSENT/ REDUCED OR MODIFIED INTO SPINES --TO REDUCE WATER LOSS BY TRANSPIRATION
9
ADAPTATIONS OF DESERT PLANTS
2. STEM IS GREEN AND DOES PHOTOSYNTHESIS 3.STEM STORES WATER, SO IT IS THICK AND FLESHY
10
4.DEEP ROOT SYSTEM TO COLLECT MAXIMUM WATER FROM DEEP SOIL
11
5.THICK WAXY LAYER ON STEM PREVENTS WATER LOSS
12
ADAPTATION IN DESERT ANIMALS
1.CAMEL HAS LONG LEGS TO KEEP THE BODY AWAY FROM HOT SAND. 2. IT STORES FOOD AS FAT IN ITS HUMP. 3. IT CAN STORE WATER IN ITS BODY.
13
4. HOOFS OF A CAMEL WELL SUITED FOR WALKING ON SAND
5. LONG EYELASHES TO PREVENT SAND FROM FALLING INTO THE EYES
14
SOME ANIMALS REMAIN IN BURROWS DURING THE DAY & COMES OUT DURING NIGHT
15
DESERT ANIMALS IN BURROWS
16
2.MOUNTAIN REGIONS 1.MOUNTAIN TREES GROW IN CONICAL PATTERN WITH SLOPPING BRANCHES – HELPS SNOW TO SLIDE DOWN.
17
2. THEY HAVE NEEDLE SHAPED LEAVES-HELPS WATER AND SNOW TO SLIDE DOWN
18
ANIMALS IN MOUNTAIN REGION
1.A SNOW LEOPARD IS WHITE IN COLOUR –CAN HIDE IN THE ENVIRONMENT. 2.THICK FUR –TO PROTECT FROM COLD 3.CLAWS TO PREVENT SLIPPING ON THE SURFACE OF SNOW
19
MOUNTAIN GOAT 1.THICK WHITE FUR
2.STRONG HOOFS FOR RUNNING UP THE ROCKY SLOPES.
20
YAK LONG THICH FUR OF YAK PROTECT IT FROM SEVERE COLD IN THE WINTER
21
3. GRASS LANDS 1.LIGHT BROWN COLOUR- HELPS TO HIDE IN GRASS LAND
LION 1.LIGHT BROWN COLOUR- HELPS TO HIDE IN GRASS LAND 2.LONG CLAWS WHICH CAN BE WITHDRAWN INSIDE. 3.BOTH THE EYES INFRONT OF THE HEAD-GIVES CORRECT IDEA ABOUT THE LOCATION OF THE PREY
22
DEER 1. CAN RUN FASTER—TO ESCAPE FROM THE PREDATORS.
2.STRONG TEETH –CHEWING HARD STEM. 3.LONG EARS –TO HEAR THE MOVEMENTS OF PREDATORS. 4. EYES AT THE SIDE OF HEAD ALLOWS TO LOOK IN ALL DIRECTIONS FOR DANGER
23
PREDATOR & PREY A PREDATOR EATS THE PREY. THE HUNTER IS THE PREDATOR
THE ONE WHO IS HUNTED BY THE PREDATOR IS THE PREY
24
II.AQUATIC HABITAT - OCEAN
25
AQUATIC ANIMALS 1.STREAMLINED [BOAT SHAPED] BODY.-FOR EASY MOVEMENT IN WATER 2.GILLS FOR RESPIRATION 3.BODY IS PROTECTED BY SCALES GILLS
26
BLOW HOLES DOLPHINS AND WHALES HAVE NOSTRILS TO BREATHE AIR FROM ATMOSPHERECALLED BLOWHOLES
27
PONDS AND LAKES
28
WATER PLANTS SOME HAVE ROOTS FIXED IN THE SOIL G VALLISNARIA LOTUS
29
SOME ARE FLOATING SALVINIA WATER HYACINTH PISTIA
30
IN VALLISNARIA, THE RIBBON SHAPED LEAVES CAN BEND IN WATER TO PREVENT UPROOTING
31
STEM OF LOTUS IS HOLLOW ,LONG AND LIGHT.
LEAVES ARE DISC SHAPED. LEAVES AND FLOWERS FLOAT ON WATER. LEAVES HAVE WAXY COATING TO PREVENT WATER STAGNATION
32
LEAF STALK IS FILLED WITH AIR TO HELP FLOATING
33
SOME ARE SUBMERGED -HYDRILLA PLANT
34
FROGS CAN BREATHE IN WATER AND LAND. WEBBED FEET TO SWIM IN WATER.
STRONG BACK LEG TO TAKE LONG LEAPS. STICKY TONGUE TO CATCH INSECTS
35
CHARACTERISTICS OF LIVING THINGS
ALL LIVING THINGS NEED FOOD . FOOD IS THE SOURCE OF ENERGY
36
2.LIVING THINGS GROW
37
3.LIVING THINGS RESPIRE BOTH PLANS AND ANIMALS DO RESPIRATION.
DURING RESPIRATION, OXYGEN IS USED AND CARBONDIOXIDE IS RELEASED.
38
4.LIVING THING RESPOND TO STIMULI
INSECTS LIKE COKROACH, MOVE AWAY FROM LIGHT. SOME INSECTS ARE ATTRACTED BY LIGHT.
39
PLANTS TOO RESPOND TO LIGHT
SOME FLOWERS LIKE WATER LILY BLOOMS AT NIGHT. LOTUS BLOOMS IN DAY LIGHT. LEAVES OF A TOUCH ME NOT PLANT DROOPS WHEN TOUCHED.
