Adaptations of differnet animals in differnt habitats

Adaptation of animals in 4 different habitats, how these adaptations help them, adaptation of camel, cactus, fish

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.

4. Let's recall last lesson

5. Time to think!

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.

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

14. 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.

15. Arctic animals' adaptation

16. 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

17. 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

18. 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.

19. 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.

20. Let's wrap up- what you have learned today?

21. Read a book- How and why do animals adapt Open this link https://www.getepic.com/app/read/19870 you have to read this book, How and why do animals adapt? and you have to tell what you learned ( 5 points) in next class

22. Task to do Open your workbook do page number 9 till 13 ( refer to textbook 16 till 21) Answer following questions in your neat copy How do camels survive for longer periods without water? What adaptations do cacti have to conserve as much water and lose as little water as possible?
