3 Where do you think each plant or animal lives? Sort the cards to determine which plants and animals could live together in a similar climate. Be prepared to discuss why you put different animals and plants together.

4 Palm Tree Strong leaves help protect from heavy winds or rainfall. Large leaves make water loss (transpiration), however, the leaves of the palm tree are waxy to prevent water loss. Roots spread wide and deep to collect as much water as possible during times of drought.

5 Cactus Cacti with spines minimize surface area and exposure to sun. Succulents store water in fleshy leaves.

6 Labrador tea plant Has red leaves that use chlorophyll and the sun to create heat and nourishment Has a hairy stem to keep it warm.

7 Bromeliad Plant Most species grow on the branches of trees. Their leaves form a vase or tank that holds water. The tanks support a thriving ecosystem of bacteria, protozoa, tiny crustaceans, mosquito and dragonfly larvae, tadpoles, birds, salamanders and frogs.

8 Deciduous Tree As the length of night increases during the fall, leaves change color and begin to fall to the ground As the time of sunlight increases during the spring, leaves begin to bud and sprout

9 Prairie crocus Has fuzzy stems. Short roots and fast growing.

10 Polar Bear! Their white fur helps them blend in with the snow and ice. A polar bear has a layer of fat under its skin which helps it stay warm. It also has a thick layer of fur. The wide, large paws help a polar bear to walk in the snow.

11 Brown Bear Brown bears hibernate in cold weather. Brown bears also have strong arms and claws that helps them to dig for food in logs and dirt.their claws are sharp and curved which helps them catch fish.

12 Sand Verbena Ephemerals like this Sand Verbena usually germinate (sprout) in the spring following winter rains. These seeds are extremely hardy. They resist drought and heat well. They prefer lots of sun.

13 Chipmunk Store lots of nuts in their burrows (cache) to get through winter, waking up to eat from their cache every two weeks.

14 Xerophytic Cactus Cactus, xerophytic adaptations of the rose family, are among the most drought-resistant plants on the planet due to their absence of leaves, shallow root systems, ability to store water in their stems, spines for shade and waxy skin to seal in moisture.

15 Fennec Fox Are nocturnal to avoid daytime Ears help radiate body heat Have a wooly undercoat to shield it from warm days and cool nights

16 Arctic Fox Arctic foxes have beautiful white coats that act as very effective winter camouflage. When the seasons change, the fox's coat turns as well, adopting a brown or gray appearance that provides cover among the rocks and plants.

17 Red Fox Thermoregulation: fur allows them to live in cold areas as well as warm areas. Nose evaporation: sweat-like wet nose helps regulate temperature of fox during warm seasons

18 Huey Lewis the Bernese Mountain Dog Has a double layer coat As warmer months approach, they shed their undercoat Natural oils protect him from weather

19 Sloth One impressive adaptation of the sloth is the algae that it grows in its fur.this serves as camouflage.the long arms are an important component in its impressive swimming ability, which it uses when the forest floods. Almost every component of the sloth's life depends on its ability to hang upside down on branches.

20 Indian Elephant Large ears of the elephant help it to hear even very soft sounds. They also help the elephant to keep cool in the hot and humid climate.

21 Arctic Hare Has smaller ears thick coat and white fur

22 Jack Rabbits Large ears help radiate body heat Have taller hind legs than rabbits.

23 Rubber tree The rubber tree grows at heights of more than 100 feet. Its large slide shaped leaves with drip tips allow for rain to runoff and prevent fungus from growing. They have larger leaves in order to gain as much sunlight as possible.

24 Class Discussion. Which organisms did you think live together? Why? What made you decide?

26 TUNDRA The tundra is the coldest and the driest of all the biomes on Earth. There is very little rainfall in the tundra; it rains less than ten inches a year. Winters are long, and summers short, sometimes they last for only 6-10 weeks. Because the tundra is so close to the north pole, summer days are 24 hours long! Summer temperatures rarely get above 50 F (10 C), just enough to thaw the surface of the ground. What a place for a summer vacation!

27 DESERT Although few animals and plants are adapted to the extremely dry desert life, the desert is a vital biome. The desert is important because it covers about a fifth of the earth's surface! There are both hot and cold deserts. Weather is not the same in all deserts. The seasons in hot and dry deserts are usually very hot during the summer and warm during the rest of the year. During winter these deserts get little rainfall. Rain is often light, or in short concentrated bursts. Most of the time evaporation rates are faster than rainfall rates. Sometimes the rain evaporates before even hitting the ground. This is the reason for the dry characteristic of this type of desert. Coastal deserts are in moderately cool to warm areas. Coastal deserts usually have cool winters followed by fairly long, warm summers.

28 TAIGA (Boreal Forest) Long, cold winters, and short, mild, wet summers are typical of this region. In the winter, chilly winds from the arctic cause bitterly cold weather in the taiga. The length of day also varies with the seasons. Winter days are short, while summer days are long because of the tilt of the earth on its axis. Fire is not uncommon in the taiga during the summer. Taiga, also known as coniferous or boreal forest, is the largest terrestrial biome on earth.

29 Rainforests are important because they help maintain global weather patterns and rain. Water that evaporates from trees falls in other areas as rain. Tropical rainforests are lush and warm all year long! Temperatures don t even change much between night and day. The average temperature in tropical rainforests ranges from 70 to 85 F (21 to 30 C). Temperate rainforests are also wet, but not as rainy as tropical rainforests. The fog provides about 7-12 inches (18 30 C) of rain each year. Temperate rainforests are a lot cooler than tropical rainforests, but the temperatures are still mild. They often have two distinct seasons: one long wet winter, and a short drier summer. RAINFOREST S There are two types of rainforest biomes: temperate and tropical rainforests. Temperate rainforests are found along coasts in temperate regions.

30 DECIDUOUS FORESTS Most temperate, deciduous (leaf-shedding) forests are located in the eastern United States, Canada, Europe, China, Japan, and parts of Russia. This biome has four changing seasons including winter, spring, summer, and fall. These seasons happen because of the tilt of the Earth s axis. Throughout the year, rays from the sun hit different parts of the world more directly than others, causing varying temperatures, or seasons. If the Earth were not tilted on an axis, temperatures around the globe would always be the same. Temperate deciduous forests also have quite a wet environment. Following rainforests, temperate deciduous forests are the second-rainiest biome.

31 Make your animals and plants into four groups Student A- Tundra CRITICALLY THINK: Student B - Desert Which group do you think is the tundra? Student C - Tropical Rainforest Student D - Deciduous Forest Which one is the deciduous forest? Which is the desert? Which is the Tropical rainforest?
