Habitats and Adaptations Video Lecture | Science for Class 6

0:0:0: imagine that you are going on a vacation
0:0:2: to many places of interest you pack your
0:0:5: bags and go to rishikesh where you see
0:0:8: the river gandha flowing through the
0:0:10: mountains you feel the Cool Breeze and
0:0:12: hear the sound of
0:0:17: water you notice many kinds of plants
0:0:20: and animals near the river such as Ducks
0:0:22: fish Lotus Aldi and water
0:0:25: Lees you also see some people performing
0:0:28: arti and offering flow first to the
0:0:30: river you decide to climb the mountains
0:0:33: of the Himalayas where it is very cold
0:0:36: you wear warm clothes and shoes to
0:0:38: protect yourself from the low
0:0:40: temperature you see many kinds of trees
0:0:43: on these mountains such as Oaks Pines
0:0:46: and
0:0:47: deodor you also see some animals that
0:0:49: live on these mountains such as goats
0:0:52: and
0:0:53: yucks these animals have thick fur or
0:0:55: wool that keeps them warm you then
0:0:58: travel to Rajasthan and move on camels
0:1:1: through the hot desert you feel the heat
0:1:4: and see the sand dunes you drink a lot
0:1:7: of water you also see some plants such
0:1:11: as
0:1:12: cactus cactus has thorns and no leaves
0:1:16: this is because leaves consume a lot of
0:1:18: water but deserts have less water so
0:1:21: Cactus can live without water for many
0:1:24: days you have seen so many different
0:1:27: places and organisms in your vacation
0:1:30: you realize that all these places are
0:1:32: very different from one another some are
0:1:34: cold and some are hot and dry and yet
0:1:38: all of them have many living creatures
0:1:40: of various kinds you also realize that
0:1:43: all these living creatures have some
0:1:45: features that help them to live in their
0:1:48: surroundings like consider this have you
0:1:50: ever seen a camel and a fish in the same
0:1:53: place probably not right that's because
0:1:57: camels and fish live in very different
0:1:59: different places camels live in deserts
0:2:3: which are hot dry and Sandy fish live in
0:2:7: water which is wet and cool the places
0:2:10: where the animals live is called a
0:2:13: habitat now there are two types of
0:2:15: habitats like here camels live on land
0:2:18: this is called terrestrial habitat
0:2:21: terrestrial habitat can be of many types
0:2:24: like deserts forests grasslands and
0:2:28: mountains now the fishes live in water
0:2:32: this is called aquatic habitat lakes
0:2:35: rivers and oceans are some examples of
0:2:37: aquatic
0:2:39: habitats so how do these animals survive
0:2:42: in such different
0:2:44: habitats this brings us to another
0:2:46: concept of this chapter which is
0:2:48: adaptation look at this camel what do
0:2:51: you see yes it has very long legs and a
0:2:55: big hump on his back the long legs keeps
0:2:59: them far far away from the hot sand now
0:3:2: what about hums they can store water in
0:3:6: their hums they excrete small amount of
0:3:9: urine their dong is dry and they do not
0:3:12: sweat since camels lose very little
0:3:14: water from their bodies they can live
0:3:16: for many days without water which helps
0:3:19: them to survive in dry environment with
0:3:22: less water
0:3:24: availability now look at these different
0:3:26: kinds of
0:3:27: fishes what do they have in common
0:3:30: yes they have streamline shape this
0:3:33: shape helps them to swim in the water
0:3:36: fishes also have gills that allow them
0:3:38: to breathe
0:3:39: underwater fish have slippery scales on
0:3:42: their
0:3:43: bodies these scales protect the fish and
0:3:46: also help in Easy movement through water
0:3:49: you notice how the features of camels
0:3:51: and fishes are so different and helps
0:3:53: them to survive in their
0:3:55: habitat this is called
0:3:57: adaptation adaptation is is the process
0:4:0: by which an animal develops certain
0:4:2: features that help it survive in its
0:4:4: habitat now look at this picture of a
0:4:8: habitat can you see there are living
0:4:10: things and non-living things too these
0:4:13: are the two components of a
0:4:15: habitat the living things like snake
0:4:18: squirrel or trees are called biotic
0:4:21: components and the non-living things
0:4:23: like the rock here or the water are all
0:4:25: called abiotic
0:4:27: components now tell me if was no water
0:4:30: or rare would we be alive no right so
0:4:35: abiotic components are very important
0:4:37: for us to
0:4:39: survive this brings us to the end of
0:4:41: this video next time when you visit any
0:4:44: place notice the different types of
0:4:46: organisms living there and wonder how do
0:4:48: they survive in those
0:4:50: places we hope that you have understood
0:4:53: the concept of living organisms habitat
0:4:55: and
0:4:56: adaptation now here's a secret on how
0:4:59: you can study effectively with the urv
0:5:2: app you can learn with chapter notes
0:5:5: watch video lectures and solve NC based
0:5:8: McQ tests of this chapter on
0:5:11: urv and that's not all you also get
0:5:14: amazing courses for class 6 and much
0:5:16: more for your class six
0:5:18: preparation thank you
