Adaptation - Lesson 1

ADAPTING TO
THE
ENVIRONMENT

Let's review!

Camel

1. The humps --> to stores fats for extra energy

2. Nostrils --> can be closed to prevent breathing in sand

3. Long eyelashes --> to keep sand from getting into its eyes

4. Wide, padded feet --> to prevent from sinking into the soft sand.

Animals/Plants that are adapted in a hot an dry environment

Cacti

1. Needle-like leaves --> to reduce water loss

2. Thick and fleshy stem --> to store water

3. Long roots --> to absorb water and nutrients from a larger area

Animals/Plants that are adapted in a hot an dry environment

Multiple Choice

Camel and cacti are suitable to live in _____ environment.

• cold

• hot and dry

• wet

Multiple Choice

The camel stores fats in its ______ for extra energy.

• long eyelashes

• wet, padded feet

• nostrils

• hump

Multiple Choice

The function of wide, padded feet on the camel is to ________.

• run faster away from the predator

• keep fats as store of energy

• 1. prevent from sinking into the soft sand

• to keep its from the extreme heat

1. Thick fur & layer of fats --> to insulate, keep itself warm in the cold

2. Nostrils --> can be closed to prevent breathing in water when it swims

3. Feet covered with thick, black pad --> to prevent slipping on ice

Animals/plants that are adapted in Cold Environment

Polar bear

1. Thick bark --> to protect them from extreme cold

2. They shed all the leaves --> to reduce water loss

3. Cones-shaped like tree --> to prevent snow from staying on them for a long time

4. Some trees do not shed their leaves, instead their leaves are needle-like to reduce water loss.

Animals/plants that are adapted in Cold Environment

Multiple Choice

What does insulate mean?

• to breath underwater

• to lose less heat, keeping warm in the cold

• to reduce water loss

• to slip on ice

Multiple Choice

Why some trees shed all the leaves in winter?

• to store nutrients

• to protect them from the extreme cold

• to reduce water loss

• to prevent snow from staying on the for a long time

Multiple Choice

Some trees are shaped like cones to ______.

• prevent snow from staying on the for a long time

• reduce water loss

• protect them from the extreme cold

• to store nutrients

Fish

1. Long narrow body --> to help swim faster

2. Gills --> to take oxygen underwater

3. Fins & tail --> to swim forward swiftly

Animals/Plants that are adapted in a WET environment

Beaver

1. Waterproof coat --> to keep itself warm in the cold water

2. Webbed hind feet & paddle-shaped tail --> to swim in the swamp

Animals/Plants that are adapted in a WET environment

Diving beetle - with the air tube

Some adult insects live underwater—like diving beetles, whirligig beetles, water boatmen, backswimmers, giant water bugs and water scorpions. They don’t have gills or lungs. They have a network of air tubes inside their bodies and air holes along the sides of their bodies. They stick their back ends out of the water to get air. They can save air for later by collecting a bubble of air under their wings or on their back end or belly. Because insects are so small, sometimes the air bubble works like a gill. It pulls oxygen out of the water—like an air tank that refills itself.

Animals/Plants that are adapted in a WET environment

Water lily

1. Hollow stem --> to stay afloat on water surface

2. Broad waterproof leaves --> receive enough sunlight to make food

Animals/Plants that are adapted in a WET environment

Pond skater

Long paddle-like legs --> to help it glide over the surface of the water

Animals/Plants that are adapted in a WET environment

Multiple Choice

These animals/plants can live in a wet environment, except _______.

• beaver

• rattlesnake

• water lily

• pond skater

Multiple Choice

Fish have long narrow body to _______.

• glide over the surface of the water

• 1. help swim faster

• breath underwater

• stay afloat on the surface of the water

Multiple Choice

What is the function of the broad waterproof leaves on water lily?

• to be filled with water

• to reduce water loss

• to protect it from extreme cold

• to receive enough sunlight to make food
