are often found in locations with poor soil quality. In biomes like the temperate deciduous forest biomes the trees have no need for buttresses because the soil is rich with nutrients. Rich soils allows for trees and plants to grow deep roots that anchor and provide them with stability. In addition deep root systems take up nutrients that are found throughout soil. Buttresses do not penetrate into the deep layers of the soil this could affect stability in places like the desert. Also shallow roots

maps in Figures 1 and 2 describe the geographical locations of the thirteen major terrestrial biomes of the world. Because of their scale‚ these maps ignore the many community variations that are present within each biome category. Most of the classified biomes are identified by the dominant plants found in their communities. For example‚ the various types of grasslands are dominated by a variety of annual and perennial species of grass‚ while deserts are occupied by plant species that require very

THICKETS- tall shrubs or small trees are dominant 4. DESERTS- very few plants rocks‚ and soil are more dominant Later on‚ animal life and their distribution was also correlated with climate‚ giving rise to the field of BIOGEOGRAPHY.

A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra‚ taiga‚ tropical rain forest‚ temperate forests‚ desert‚ grassland‚ savanna‚ chaparral‚ and marine. Each biome has it’s own characteristics such as

A nebula‚ an immense cloud of hydrogen gas and dust‚ condenses into smaller regions of matter. On occasion‚ one of these regions collapses under the force of its own gravitational attraction‚ often triggered by an outside force‚ like a nearby supernova-an explosion of a star. After the collapse of a cloud‚ atoms begin

A habitat is an ecological or environmental area that is inhabited by a particular species of animal‚ plant‚ or other type of organism.[1][2] It is the natural environment in which an organism lives‚ or the physical environment that surrounds a speciespopulation.[3] A habitat is made up of physical factors such as soil‚ moisture‚ range of temperature‚ and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a
