Tundra is a biome that is cold and does not support trees.It is the largest and most Northern biome. It covers 1/5 of fthe earths land. It has a permanent frozen layer of soil. Animal that live there are musk oxen, artic foxes, caribou, and snowshoe hares. Estuarie is where freshwater from streams and rivers spill into the ocean, The freshwater and salt water are always mixing. Fresh water is water without salt. It is fresh with fish, and other marine animals. summer:82 winter:43 F rainfall:157.5 in. daytime: 93 F nighttime: 68 F //**Savannah:**// rainfall//: 57 in.// dry season: 93 F wet season: 61 F //**Desert:**// less than 10 in. of rain summer: 100 F winter: 45 F Water meets shore. Farther from shore. Most marine life lives here. Zone where it is very deep. Big animals live here. Ocean floor. No sunlight.
 * __Biomes__:** Taiga has long winters,during which snow covers the ground. Plants must be able to survive long winters and short summers.The biome is charactertized by ever green trees,pines,firs and spruce. Moose,bears,wolves,and lynx are some the animals that live there.
 * __Ecology:__** Biotic factors are the living components of an ecosystem. Abiotic factors are the nonliving components of an ecosystem. The flow of matter and energy begins with the sunlight and then goes to the producer.The levels of consumers start with the Producer, Primary, secondary and tertiary.Food chain are simple diagrams that show how energy and matter flow from producers to consumers and decomposers.Food webs is a complex diagram over lapping food chains in an ecosystem. Energy is transferred from the producer to the first level consumer and so on through the chain of web.The energy pryramids energy is divided up into trophic levels.The energy from sunlight is used by plants for photosynthesis, which allows plants to create energy and store some of this energy.Energy is neither created nor destroyed. The energy in each level is used by that organism for its own life functins and the remaning energy is passed onto the next level. This is usually about 10% of the original amount of energy.Competition limits population size. It can alsoprevent population growth.Population denssity is the size of population that occupies a specific area.Limiting factor is anything that restricts the numder of individals in a population. Carrying capacity is the largests number of individuals of one species that an ecosystem can support over time.
