The biosphere includes any place on Earth where life can exist.
a geographic area that is defined by 4 characteristics: climate (air temperature/ amount of snow or rain), soil conditions (will snow grow there?), plant life, and animal life. The things that live in biomes make adaptations to survive in their biome.
4 distinct seasons: winter, summer, spring, and autumn/fall
tiny holes on leaves that let water out.
usually hot and humid
perminately frozen ground
up in the leaves of the trees
Why are cicadas important to both the plants and animals in the deciduous forest?
They are an easy meal. That have no defenses.
Why do the leaves fall off of the trees in the deciduous forest in the autumn?
Trees lose their leaves to conserve water for the dry winter.
Why do most of the animals in the Tropical Rainforest live in the canopy?
That is where the food supply is. Many different fruits grow up there, bringing herbivores. That brings carnivores to prey on the herbivores.
Why can the frogs chill up in the canopy, away from bodies of water?
Because the air is so humid and wet their skin stays damp.
Why are the frequestn fires of the temperate and tropical grasslands so important to the soil of those biomes?
Burnt grass brings nutrients to the soil.
What are three behavioral adaptations kangaroos have made that allow them to survive in the deserts of Australia?
1). They lick themselves to make their body temperature cooler. 2). They find the shade of the trees to keep cool. 3). They did deep into the soil to get to cooler dirt to lay on to keep cool.
Climate: temperate, four even seasons Trees: deciduous=leaves falling. leaves fall to conserve water for the dry winter Animals: Black bears, ducks, coyotes, chipmunks, salamanders, white tailed deer. some hibernate, some migreate, some stay. Dead sacadas add nutrients to soil and are an easy meal with no defenses. Soil: Great soil for farmers. Crops grow easily. Ties with Temperate Grasslands for "best place to farm". Soil is good because cicadas and leaves bring nutrients to soil. Where is it?: most of the Eastern half of the U.S.
Climate: Has four seasons but winter is clearly the longest season. cold. not much precipitation Trees: Pine trees. Seeds in pine cones. Pine trees have needles which have a thing waxy coating to prevent water loss because Coniferous Forest doesn't get much precipitation. Animals: Moose, lynx, grey wolves, ptarmagin, wolverines. They have think coats of fur. Most hibernate or migreate. They hibernate to conserve energy so they don't have to look as hard for scarce food or deal with the extreme cold. Soil: very poor. not much farming goes on, leaves don't fall so ground isn't replenished with nutrients. the cole makes it hard to grow crops. Where is it?: Northern states and southern Canada. Northern Wiscomsin, Michigan, Minnesota, Canada.
Climate: Warm & Wet. No seasons. has somewhat of a dry season; during rainy season, it rains everyday. huge amount of rain year-round. Trees: more diversity of trees and plants in this biome than any other biome. branches start at 100 feet up because only 2% of sunlight gets to jungle floor (the trees absorb the sunlight before it can get down to the floor). the leaves are grooved so that water can run off of them easily. Animals: most species of animals in this biome than any other biome. Includes monkeys, jaguars, parrots, snakes, frogs. The frogs can stay in canopy instead of living near/in water because there is so much moisture in the air. they chill up in the canopy. ththey stay up there because there is more food for them and less predators because that's where the food is. there are fruits that grow up there which attracts herbivores. the herbivores attract carnivores. a lot of predators can't get up there. Soil: very poor. so much rainfall that nutrients & siol are just washed away. so much vergetation that it uses the nutriest as soon as they are added to the soil. also sunlight can get down to soil. farmers clear Tropical Rainforests and soil is so poor, farmers can only use it for two years before they have to go elsewhere. fungi also competes with plants for nutrients. Where is it?: near the equator. equatorial Africa, South America, Asia, and Carribbean
Climate: 4 seasons, little precipitation. rain is distributed evenly year-round. Trees: very few trees because 1) not much rain, 2) MANY fires. Animals: Bison, prarie dogs, coyotes, pronghorns. They are grazers. Soil: full of nutrients because of all the fires which add nutrients. when grass is burnt it always grows back because of the little safety bulbs down below. Where is it?: Bread basket, Great Plains, Midwest, Kansas, Nebraska, South Dekota, Iowa, east Colorado.
Climate: warm all the time. two seasons: the rainy (wet) season and the dry season, both in which they get EXTREME! you wouldn't want to be a farmer here because it gets to serious extremes during both seasons. for exp.: there are many fires in dry season and extreme floods in wet season. Trees: not lots of trees because frequent fires and little rainfall. the grazers eat the seedlings off the small trees. Animals: Many hooved animals, herbivores, and large carnivores (predators). Antelope, zebra, giraffe, wildebeast, lions, and cheetahs. Soil: Farming does occur, but this isn't the best place for it because of the extreme wet & dry seasons, it's hard for crop to survive Where is it?: Africa, Australia, South America, & India
Climate: extreme temperatures. little precipitation. very warm during the day; cold at night. the plants & animals that live there have to make adaptations to survive. Trees: very few trees can survive because of lack of precipitation. the few trees are used as shade to keep animals cool. plants here adapt to lack of water by being able to store water, having spines instead of leave to protect them from animals that try to steal their water. cactus don't have leaves because they'd lose water through stomata. they have a shallow root system to suck up rain. Animals: lizards. lizard skin is efficient of retaining water so they can survive with their scales. others are mammals like jack rabbits, gray gox, coyotes, & mountain lions. many are nocturnal because it's easier to hunt in cooler night temperatures. animals here have large ears to help get rid of heat. Soil: not about to sustain crops because of lack of water and the scarcity of plants that would grow and provide nutrients to the soil Where is it?: California, Arizona, Nevada, New Mexico.
Climate: cold. 10-10.5 months of winter a year. the permafrost (perminately frozen ground) keeps plants from growing. small precipitation, mostly of snow. Trees: no trees in the Tundra. Lack of water and permafrost cause this. Even during the summer the ground is frozen a couple of inches below the surface. No trees can root in this. Animals: Polar bears, caribou (che putting moose ears up doing carlos mencia's 'dee dee dee' saying it's me), musk ox, lemmins, wolves. they have thick fur coats to keep warm. they turn white to blend in for safety. they have small ears to conserve heat. they have compact bodies to conserve heat. Soil: not useful for farming. only plants that can grow have very shallow root systems because of the permafrost. six weeks (very short) growing season-crops need more time to grow than that. Where is it?: Alaska, North Canada, North Russia
talk about the lemmings and why they jumped off the cliff
they were looking for food
what do the broad and flat shape of deciduous forest leaves do
they help absorb sunlight
describe one similarity between deciduous and coniferous
both are temperate so both have 4 seasons
