This document discusses animal adaptations to different habitats. It provides examples of how camels, cacti, polar bears, and fish have adapted to survive in deserts and Arctic environments. Camels have adaptations like thick fur, the ability to go long periods without water, and slit-like nostrils to survive in hot, dry deserts. Cacti store water in their stems and have widespread root systems and spines instead of leaves to minimize water loss. Polar bears have white fur for camouflage, thick layers of fat and fur for insulation, and large feet to distribute their weight on ice. The document also notes fish have gills to breathe underwater and streamlined bodies to reduce resistance while swimming. Adaptations help

1. Habitats- Adaptations

2. Learning
objective
 Explain that different organisms found in two
different habitats differ because of differences
in environmental factors [for example, the
availability of light, water, vegetation and
climate.

3. Students will learn
About different condition animals need in different habitats
Adaptations of different animals and plants

4. Let's recall last lesson
What you learned about habitats?
Can you tell something about desert?
Living conditions over there? Climate?
What sort of animals and plants we will
find there?
Can we find camel and cactus in
rainforest? Why ?

5. Time to think!
What factors determine the types of plants or animals that can survive in
an area?
Adaptation! What comes to your mind when you read word adaptation

6.  Think about the way you dress in the winter. You don’t wear
your shorts and bathing suit when it’s snowing outside! You
wear warm clothes, and maybe even a hat and mittens to
protect yourself from the weather.
 And what if you are having a snowball fight? You probably
run away from the person throwing at you, and maybe even
try to sneak up on that person and throw some snowballs!
 The way you dress in the winter, as well as the way that you
run and hide from someone throwing snow at you are kinds
of … Adaptations.

7. Adaptation
 Every organism has a unique ecosystem
within which it lives. This ecosystem is its
natural habitat.
 This is where the basic needs of the
organism to survive are met: food, water,
shelter from the weather and place to breed
its young.
 All organisms need to adapt to their habitat
to be able to survive.

8. Contd
An animal's environment consists of many different
things. The climate, the kinds of food plants that
grow in it, other animals that may be predators or
competitors- the animal must learn to adapt to each
of these factors in order to survive.
This means adapting to be able to survive the
climatic conditions of the ecosystem, predators, and
other species that compete for the same food and
space

11. Adaptation in Desert
 It may seem like nothing can live in a desert
because it’s so dry. But most deserts are full
of life, with plants and animals that have
adapted to survive without much water.
 Some plants, like cacti, store enough water
in their stems to last until the next rain.
 Desert animals also have adaptations that
help them survive without much water.
 Kangaroo rats in the Sonoran Desert get
water from the seeds they eat. Some
carnivores, such as desert foxes, get enough
liquid from their prey.

12. Adaptation of Camel
 Camels are well adapted for survival in the desert.
Their adaptations include:
 large, flat feet - to spread their weight on the sand
 thick fur on the top of the body for shade, and thin fur elsewhere to
allow easy heat loss
 the ability to go for a long time without water - they lose very little
water through urination and perspiration
 the ability to tolerate body temperatures up to 42°C
 slit-like nostrils and two rows of eyelashes - to help keep out sand

13. How camel
adapt to
desert life

15. Adaptation of Cactus
Cacti are also well adapted for survival in the desert.
Their adaptations include:
stems that can store water
widespread root systems that can collect water from a
large area
In addition, cacti have spines instead of leaves. These
minimize the surface area and so reduce water loss
by transpiration. The spines also protect the cacti from
animals that might eat them.

16. Arctic animals'
adaptation

17. Arctic
 You won’t find trees in Antarctica, but
some types of small shrubs, lichens,
mosses, and algae are able to grow in
the harsh climate.
 Polar bears and arctic foxes are adapted
to the extreme weather of the Arctic
region
 Animals living in these regions have fur
on their body to protect them from
extreme cold weather

18. Polar bear
 Polar bears are well adapted for survival in the Arctic. Their adaptations include:
 a white appearance - as camouflage from prey on the snow and ice
 thick layers of fat and fur - for insulation against the cold
 a small surface area to volume ratio - to minimise heat loss
 a greasy coat that sheds water after swimming - to help reduce heat loss
 large feet - to distribute their load and increase grip on the ice

19. Adaptation of a fish
Fish have gills that allow them to “breathe”
oxygen in water.
Fish have a stream-lined body. They are
typically long and narrow, which reduces
water resistance when they swim.
Most fish have several fins for swimming. Fish
have a system of muscles for movement.
Most fish have a swim bladder. This is a
balloon-like internal organ that contains gas. By
changing the amount of gas in the bladder, a fish
can move up or down through the water column.

20. Camouflage
 Did you know that animals camouflage themselves so they can
adapt to their environment?
 Adaptation can protect animals from predators or from harsh
weather.
 Many birds can hide in the tall grass and weeds and insects can
change their colour to blend into the surroundings.
 This makes it difficult for predators to seek them out for food.

21. Let's wrap up- what you have learned today?
Can you tell why adaptation is important ?
Why polar bear cannot survive in a desert?
How do you think bushy eyebrows help camel survive in a desert
Cactus can survive in a desert, which 2 adaptations help it live with little water?

22. Read a book-

do animals
adapt
