Task: Read the pages and text below thoroughly and complete the question answers:
Worksheet/Exercise:
Animals and plants are adapted to the conditions of the habitats in which they
live.
Animals live everywhere on Earth. Some places on Earth are very hot and some are very
cold. Some places on Earth have a lot of water and plants, and other places have very little
water and few plants. More than 99 percent of Antarctica is covered with ice but a few plants
still grow there, mostly lichens, mosses, and algae. Antarctica is very cold.
Guess what?
Animals even live in Antarctica! The animals in Antarctica are dependent on the sea for feeding
or are migratory and leave the continent when the winter arrives.
Animals can live in many different places in the world because they have special
adaptations to the area they live in.
What is an adaptation?
An adaptation is a way an animal's body helps it survive, or live, in its environment. Camels
have learned to adapt (or change) so that they can survive.
Animals depend on their physical features to help them obtain food, keep safe,
build homes, withstand weather, and attract mates. These physical features are
called physical adaptations. They make it possible for the animal to live in a particular place and
in a particular way.
Each adaptation has been produced by evolution. This means that the adaptations have
developed over many generations.
Examples of the basic adaptations that help creatures survive:





shape of a bird's beak,
the number of fingers,
colour of the fur,
the thickness or thinness of the fur,
the shape of the nose or ears

Adaptations for Survival
Lesson 1 Vocabulary
⇒ Adaptation: anything that helps an animal live in its environment - can include body
coverings and body parts
⇒ Skin: the outer covering of an animal’s body - forms an outer covering for protection of body
organs - Keeps the bodies of some animals at the correct temperature - Sensitive to outside
temperature change and pain - Can hold water or release it depending on an animal’s needs
(amphibians)
⇒ Scales: small, thin plates that are part of the skin covering (some fish and reptiles) - can be
smooth, rough, or pointed - added protection for the skin
⇒ Feathers: strong, lightweight outer body covering of birds - parts of the feather lock together
(hook lets) so hardly any air can pass through - covered with a layer of body oil (oil waterproofs
birds’ feathers, keep a bird’s skin dry, keep its body temperature correct, and help the animal
float)
⇒Down: soft, fluffy feathers on baby birds - in older birds, down feathers are found close to the
skin - keep the bird’s body at the correct temperature
⇒ Fur: covering of thick, soft hair down feather hook let - thick fur traps air close to the
animal’s body - the air is warmed by the animal’s body, keeps the animal’s body at the correct
temperature
Adaptation-is anything that helps an animal survives in its environment.
Outer body coverings-help an animal survive by:
1. protecting its internal organs
2. helps regulate body covering
3. sensitive to temperature changes and pain
Fish have scales for outer body coverings
Birds have feathers for outer body coverings
Bears have fur for outer body coverings
Body parts used for protection:
1. Cats have claws for protection.
2. Wolves use their teeth for protection
3. Fish use their scales for protection
Body parts use for food getting:
1. A bird uses its bill for getting food
2. A snake uses its curved teeth for food getting
3. A bear uses its claws for getting food
4. A fish uses its mouth for getting food

Task: Quiz question answer
Worksheet/Exercise:
Vocabulary
Adaptation: A specific feature that allows a plant or animal to live in a particular
environment.
Characteristics: Features that make plants and animals different from each other.
Examples are leaf shape, body covering, number of legs, and how animals move.
Camouflage: A way of blending into the surroundings so that an organism cannot
be seen. Also called “protective coloration.”
Environment: The living and nonliving things that surround an organism.
Hibernation: When organisms become inactive for a period of time for survival,
such as during cold winter months.
Migration: When organisms move from one environment to another to find food
or a mate.
Mimicry: When an organism resembles the appearance, actions, or sounds of
another organism.
