Adaptations, Habitats, Biomes
Essential Questions Read through the following presentation with your group and teacher. See
if you can answer these questions by the end
What is an adaptation?
What is the difference between physical and behavioral adaptations?
What is a biome? What are the major biomes?
What kinds of animals belong to each biome?
How do biomes affect animal adaptations?
How to animal adaptations change over time?

What is an adaptation?
How a person or animal changes or “adapts” to survive.
We change how we dress. When the weather gets coldwe wear coats and long pants. Similar to this animals
must adapt to changes in their surroundings.
What do all animals need?
Air (oxygen), water, shelter, food
What animals do or how they behave to get these needs
is called an adaptation.

Physical Adaptations
Physical adaptations may be how many fingers an animal has, how thick its fur it, orhow it changes to attract a mate.
Physical adaptations do not form overnight. They can take hundreds of years totransform and usually change because of the climate.
With today’s constantly changing environment, animals habitats or living places arechanging.
An animal has to readjust to that new surrounding or climate. If they can’t theanimal dies.
You will learn more about how climate changes and then with time it forces animalsto change and adapt later in this lesson.

Adaptations- Physical
Mimicry The Viceroy Butterfly mimics the
Monarch. The Monarch is poisonous
and birds know not to eat it. The
Viceroy is not poisonous but because it
looks similar, many animals will not eat
it. What other animals use mimicry?
Camouflage The chameleon’s light brown coloring
keeps it safe from harm. It matches the
trees and brush it lives in so predators
cannot see it. The chameleon onlychanges color when in immediate
danger. What other animals use
camouflage?

Adaptations- Physical
Defense
Bombardier beetle- a beetle that has a
special defense feature. It mixes two
chemicals in its body and shoots thechemicals mixed in its body from its
abdomen at predators for protection.
The skunk uses a special musk to spray
when it feels it is facing danger.

Behavioral Adaptations
Migration This is when animals move from oneplace to another in search of food or
to find a warmer place to live.
Hibernation/Estivation When an animal goes in a dormant or
inactive state to avoid extremely cold
weather conditions. Brown bears
hibernate in the winter. Estivation is thesame as hibernation but is done by
animals trying to avoid very hot
conditions.

Behavioral Adaptation- Caring for an animals’
young
Crèche Crèche is the term used for how amother duck leads her ducklings asshe searches for food. In a crècheone female leads the group ofducklings and the other trails in theback guarding them from danger.This can be considered an adaptationused to care for the young.
Spiders have many spider eggs at onetime; therefore they cannot all live inthe same area. As a special
adaptation and means of survival young spiders find a pace to live byballooning. They raise their abdomenor rear, spin a long strand of silk andlet the breeze carry them to a newhome.

Adaptations are everywhere!
There are many more types of adaptations both physicaland behavioral. What other kinds of adaptations ofanimals do you know?
You will use the following WebQuest to find even moreadaptations!
Now it’s time to learn about where these animals live andhow that affects their adaptations.

BiomesThere are six major types of biomes where all animals
could live and “adapt” to in order to survive.Freshwater -Includes wetlands, streams and rivers, ponds and lakes.
Animals that live here require low salt intake. Temperature of the waterchanges drastically with the seasons.
(fish such as catfish, shrimp. ducks, turtles, snakes, birds)
Marine – Cover about 75% of Earth’s surface. Marine includes oceans,estuaries, and coral reef. High salt concentrations.
(mammals such as dolphins and whales, crabs, worms, octopuses)
Desert –Cover about 20% of Earth’s surface. Few animals live in very hotdeserts because the desert offers little protections from the hot sun. Semi-arid, coastal, coastal, and cold deserts contain more animals.
(rabbits, skunks, owls, snakes, jack rabbits, mice, coyotes, and badgers)

Biomes- Continued
Forest (Taiga)- There are three types. tropical, temperate, and boreal.Tropical-near equator(birds, bats, small mammals.)
Temperate-eastern North America, northeastern Asia, and western and central Europe(squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, and black bear.)
Boreal-short, moist summers, long cold winters
(hawks, small mammals, bats, lynx, bears)
Grassland– Two types savannah and temperate (includes prairies). Africa, India, South America.(Savannah-giraffes, zebras, buffaloes, kangaroos, mice, moles, gophers, ground squirrels, snakes, worms,
termites, beetles, lions, leopards, hyenas, and elephants.)
(Temperate- gazelles, zebras, rhinoceroses, wild horses, lions, wolves, prairie dogs, jack rabbits, deer, mice,coyotes, foxes, skunks, badgers, blackbirds, quails, sparrows, hawks, owls, snakes, grasshoppers, andspiders)

Biomes- Continued
Tundra- Two types; Arctic and Alpine. Arctic is coldest of all biomes. Tundrameans “treeless.” characterized by short growing seasons and reproduction seasons.
Arctic- Northern Hemisphere, North Pole
(lemmings, caribou, arctic hares, squirrels, arctic foxes, wolves, polar bears, snowbuntings, falcons, loons, terns, snow birds, mosquitoes, flies, moths, grasshoppers,
black flies, salmon, and trout)Alpine- very high mountaintops of Alaska and Washington.
(marmots, mountain goats, sheep, elk, beetles, grasshoppers, butterflies)
