Document Summary
(7) intertidal zone: where the ocean meets lad. Organism have to be adapted to a variety of conditions (8) near shore zone: extends out to sea from low-tide line (9) open ocean. Currents accumulate garbage: shallow water marine biomes. Distribution depends on temperature & precipitation: climates: weather patterns that prevail for years or centuries in a speci c region, desserts. Become hotter & wetter closer to the equator: tropical rainforest. All of the nutrients are in the living vegetation so the soil is very poor. Typically located in the centre of continents. Large mammals (ex. bison) prevent growth of trees. Only 1% left - rest is used for farming: temperate rainforest. Deforestation - large trees = 13328: coniferous forest. Trees have short branches to shed snow. Trees are unable to establish root system & grow = no trees. Many animals migrate up north during summer for breeding. Extremely cold during winter, high winds, little day light.
