The five basic needs of animals are

• Air
• Water
• Food
• Shelter
• Space

3
In your mind, choose two animals.

• What adaptations do these animals possess?
• Is each animals adaptation an adaptation for
  growth and development, survival or reproduction?

4
My First Pick

• A polar bear has thick white fur to keep it warm
  (purpose survival). Its fur also helps it to
  blend in with its artic environment (purpose
  camouflage for survival).

5
My Second Choice

• The bright red body of a male cardinal helps it
  attract a mate (purpose reproduction). In
  other animals, bright colors tell predators to
  stay away. They have learned the animal is
  poisonous!

16
Mild Forest Ecosystem Food ChainIf one of these
organisms were taken out, how would this affect
the rest of the food chain?
17
What is an example of an inherited trait?

• Eye color
• Hair color

18
Learned behaviors are behaviors that animals
learn through experience. Give an example of a
learned behavior.

that are automatic. Give an example of an
instinctive behavior.

• A Spider spinning a web.
• Migration
• Baby sea turtles going to the sea.

20
What is an inherited behavior?

• An inherited behavior is much like a reflex. It
  is a behavior that is inherited from our parents,
  such as scratching an itch or crying.

21
What is a metamorphosis?

• A change in body form.

22
List the steps of a complete metamorphosis.

• Egg
• Larva
• Pupa
• Adult

23
List the steps of an incomplete metamorphosis.

• Egg
• Nymph
• Adult

24

25
What is a vertebrate?

26
What is an invertebrate?

• An invertebrate is an animal without a backbone.

27
What are the characteristics of a fish? Identify
one animal in this class.

• Breathes through gills
• Has a backbone
• Covered with scales
• Cold-blooded

28
What are the characteristics of amphibians? List
one animal in this class.

• Lives part of life in water and part of life on
  land.
• Cold-blooded
• Has a backbone
• Has smooth, moist skin and no scales
• Usually goes through a metamorphosis

29
What are the characteristics of reptiles? List
one animal in this class.

• Dry, rough, scaly skin
• Has lungs for breathing
• Cold-blooded
• Has a backbone
• Most hatch from eggs

30

example of an animal in this class.

• Has feathers
• Warm-blooded
• Hatches from an egg
• Has a backbone
• Has a beak
• Has two legs and two wings.

31
What are the characteristics of mammals? List

• Babies are fed with milk from the mothers body
• Has a backbone
• Has a well-developed brain
• Warm-blooded
• Has fur or hair

32
Identify one environmental change and describe
how this change could either be beneficial or
harmful to the ecosystem.

• Fire can be both beneficial and harmful. Fire can
  destroy our land and animals habitats but it can
  also clear away dead or diseased plants and brush
  to make new room for organisms to grow.

33
Identify one environmental change that can be
caused by humans.

• Fire
• Construction

34
List three differences between an insect and an
arachnid and one thing these organisms have in

  have 8, insects have 3 body parts and arachnids
  have only 2 body parts and insects can fly and
  arachnids can not fly
• Common they are both invertebrates

35
List three differences between a reptile and an
amphibian and two things these organisms have in
common.

• Differences reptiles have dry, rough, scaly
  skin and amphibians have smooth moist skin,
  reptile babies look like smaller copies of their
  parents and most amphibians go through a
  metamorphosis, and amphibians have gills part of
  their lives and lungs the other part of their
  lives, reptiles breathe through lungs all their
  lives.
• Common they are both cold-blooded vertebrates
