Habitat
= the neighborhood an animal lives in.
Beaver
Where does he live?
Builds himself a lodge in lakes and wetlands

HabitatHow is the beaver equipped to live in this
environment
Beaver
Thick oily fur to keep him warm
Broad flat tail to swim
Webbed hind feet
Long teeth (incisors) to cut down trees

Habitat
• Provides shelter• Provides food and water• Has a climate to which animals are adapted• Has other animals of the same species so that
they can reproduce
The environment in which a species lives is called its habitat.

Adaptation
• Adjustments of a species to be more suited to live in an environment

Plant adaptations
Attraction through smell
Attraction through imitation

Plants need the help of insects to fertilize their flowers
![Page 37: Habitat and Adaptations](https://reader035.fdocuments.in/reader035/viewer/2022062410/56816570550346895dd804e7/html5/thumbnails/37.jpg)
Plant adaptations
• How to attract insects for fertilization– Smell – Imitation
![Page 38: Habitat and Adaptations](https://reader035.fdocuments.in/reader035/viewer/2022062410/56816570550346895dd804e7/html5/thumbnails/38.jpg)
• The needles of coniferous trees allow them to grow in colder regions.
• Needles are covered with thick waxy layer to conserve water and heat.
Plant adaptations – where they live

• succulent plants store water in their trunks to survive the dry season
Plant adaptations – where they live

Plant adaptations – where they live
• = algae and fungi living together
• Algae provides food – (photosynthesis)
• Fungi provides moistureLichen
Symbiosis:A mutually beneficial relationship between two living organisms
![Page 41: Habitat and Adaptations](https://reader035.fdocuments.in/reader035/viewer/2022062410/56816570550346895dd804e7/html5/thumbnails/41.jpg)
Plant adaptations• How to withstand climate.– Needles of coniferous trees more resistant.– Algae of lichens are protected by mushrooms.– Cacti store water in their stems.
