  1. Habitats, biomes and ecosystems

  3. Stop Drop and Read

  4. What are Biomes? • Biome: A major environment that is based on the climate (temperature and weather) and plant life.

  5. What is a Habitat • Habitat: The place where animals live. • For tiny insects and bacteria, a habitat can be a bush or a pond. • For large animals, a habitat can be as big as the entire biome • Most of the time, habitats are local and smaller than biomes

  6. Tundra

  7. Tundra • “the frozen desert” • Only 6 – 10 inches of rainfall a year • Covers 20% of the earth’s surface • It includes the North Pole • Very cold: average temperature: -70 °F • Average Summer: -60°F – 37F • Average Winter: -18°F - -90°F • The ground is permafrost: Always frozen • No trees: too cold and frozen soil • Only moss and shrubbery • Winter: Always night time • Summer always day time • Plants adapt to grow in poor frozen soils during the summer • Animals have very thick fur to survive the cold weather • Short ears and legs to keep from losing warmth • The blood circulates close to the body

  8. Taiga • Largest Biome in the world with the most trees • Gives off most of the planet’s of Oxygen and takes up most of the carbon dioxide • Lots of insects so there are lots of birds who come to eat • Birds adapt to the cold by making an extra layer of feathers • Animals adapt to the cold with extra fur and fat to keep them warm • Animals adapt with seasonal changes with changes in fur or feather color • 12-33 inches of rainfall a year usually during summer • Lots of coniferous trees: trees that make cones • ever greens and pines • Are not a lot of species because of harsh winter • Very cold: average temperature: -70 °F • Average Summer: -7°F - 21°F • Average Winter: -54°F - -1°F

  9. Alpines • Cold windy and snowy • Below freezing temperatures during the winter • Very high altitude • Mountain regions • Coniferous trees: evergreens • Only warm blooded animals survive the cold • Animals adapt by migrating when it gets cold, lots of insulating blubber (fat to keep warm), and hibernating • At a certain height, there is a tree line: no trees can grow. To cold and not enough Carbon dioxide • Tundra like plants grow: wildflowers and mosses

  10. Deciduous Forest • Cool environment: Average Annual temperature of 50°F • Temperature changes a lot through out the year • Gets warm during the summer months and very cold during the winter month • Average summer temperature of 70°F • Average winter temperature 25°F (a little below freezing) • Wet environment: average rainfall is 30 to 60 inches a year. • 4 distinct seasons • Tree leaves change color in autumn and fall off in the winter • Trees adapt to the winter by saving food and water. They stop giving the food and water to the leaves and let them change colors, turn brown, and then die and fall off. They regrow in the Spring • Food is scarce (rare) during the winter months • Animals adapted to changing temperature by hibernating migrating to warmer areas during the winter • Some animals gather and store food during the summer for the winter • Some animals have a behavioral adaptation, food • Most animals are camouflaged to look like the ground

  11. Tropical Rainforest (jungle) • Year round warmth because it is near the equator • Very Wet and humid (wet heat) • Year round temperature between 70°F - 90°F • Over 100 inches (up to 160) rainfall a year • The most biodiversity (different types of trees and animals) • Nice warm temperature and lots of food for animals • Over 15 million species of plants and animals • Animals have adapted to life in trees • Many animals never set foot on the rainforest floor • Bright colored plants so there are bright animals as well as brown and green animals to camouflage • Many different types of foods, animals adapt to eat foods that no other animals eat • Plant adaptations for the wet: shed water off leaves quickly, drip tips and grooved leaves

  12. Grass Lands

  13. Grasslands/Prairies • Cold as -40° F in the winter and as hot as 90° F • Enough rain to make grass, not enough dependable rain for many trees • Fires also keep trees from growing • Around 30 inches of rain a year • Two main types of grasslands • Tall grass: humid very wet • Short grass: Dry with hotter summers and colder winters • Decent wildlife (80 species of animal, 300 birds, and hundreds of plant species) • Many prey animal species are small and have adapted to hide in the grass. • Large animals that live in grasslands adapt with camouflage and speed. • Large animals also live in herds that give protection with numbers for the weaker members. • Weak animals are in the middle • More eyes in a herd to spot predators

  14. Savanna • Similar to grasslands, found in different parts of the world • 4 inches of rain during dry season and 20-40 inches during the monsoon wet season • Found between tropical rainforest and desert biome • Hot and Dry: Not enough rain for forests: Few scattered trees • Summer highs: 93° F Lows: 73° F • Winter Highs: 73° F Lows:40° F • Large herds of grazing animals • Each animal has specialized eating habits that reduces food competition • Lots of large grazing animals that eat the plants and lots of carnivores that eat the herbivores. • During dry season, very little water and very high competition • Animals adapt to dry season by migrating • Most animals have adapted long legs or wings for long migrations • Some burrowing animals hibernate during the dry season • Lightning can strike and create fire during dry seasons • Animals have adapted to be fast and outrun the flames or burrow in the ground and avoid the flames • Many burrow to avoid heat and raise young

  15. Desert • 20% of the earth’s surface • Very little rainfall: about 6 inches a year • Some areas get ½ an inch. Some up to 15 inches a year • Hot and Dry with out many plants • Very short trees, ground hugging bushes, cactus • Plants adapted to store water for long periods of time and live in the hot dry weather • Very large temperature fluctuations (changes) • During the day as hot as high as 120 ° F and then down to 40°F during the night (sometimes it goes below freezing) • Too hot to live in the sun and heat: • Animals adapt and burrow under ground • Animals have adapted to be nocturnal. They come out at night when it’s cooler and hunt • Some animals don’t even drink water! They get their water from the insects, seeds and plants that they eat • Animals have adapted to find the little water sources that exist
