Primary succession begins in barren areas, such as on bare rocks exposed by a retreating glacier. The first inhabitants are lichens or plants-those that can survive in such an environment . Over hundreds of years these “pioneer species” convert the rock into soil that support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil

Temperate Deciduous Woodland Biome Deciduous tree: a tree that sheds its leaves in the autumn months, when water supply is limited. By losing its leaves, trees will prevent water loss through transpiration. Also they will have more energy to grow upwards, to reach the limited amounts of sunlight in the winter, instead of through photosynthesis. The leaves of deciduous trees are broad and thin so that there is a larger surface area for maximum photosynthesis in the summer when there are long days

Forest ecosystem FOREST ECOSYSTEM A forest is more than just the trees. A single forest is a complete, functioning ecosystem that supports innumerable plant and animal species as well as earth, water, and air subsystems. The subsystems provide the essence of life of the forest and are in themselves a byproduct of forest systems, all of which are reciprocal and inter dependent. A forest ecosystem is a complex of living and non-living elements which interrelate. An ecosystem can be small

gave a speech much like the letter your are reading at this very moment. I imagine you are wondering who I am. Well, I am Dr. Schoenborn, I am from Brazil and I study the effects of climate change in the Tropical Rainforest. Currently the Rainforest biome is experiencing the effects of climate change, but it is on the breaking point of a real hell on Earth. If we allow the wasteful and careless methods of today to continue...and get out of hand. The Rainforest could, and shall experience major heat

South Africa Introduction South Africa lacks an abundance of clean drinking water. In order to plant their crops or quench the thirst of their children, women have to walk long distances to a pump that retrieves groundwater. After, they have to carry the large container back home on their heads or in a wheelbarrow. One entrepreneur, Trevor Field, paired up with an inventor to find a solution to this problem. He came up with the PlayPump, a roundabout outdoor pump where kids played and water gets

James Shin Per 7b/8 Ecology Take Home Test 1) In the given info, there were two groups, an experimental and control group of flowers and sagebrush in a desert landscape that were identical except that the experimental group had a fence enclosed around it. Also, there was a predation relationship between the wildflowers and the kangaroo rats because the kangaroo rats eat wildflowers. Assuming that the fence was limiting the space of the experimental plot, competitive exclusion caused the extinction

Common Wealth of Kentucky. Kentucky is part of the temperate deciduous forest biome. This biome is found primarily in eastern North America. The average amount of rainfall per year is between 30-40 inches and rainfall occurs throughout the year. The pre-dominate plants in the region are large trees which lose their leaves during the fall. These trees are deciduous, hence the name temperate deciduous forest biome. The climate in Scott County, Ky (the specific county where I live) is in zone

contentment. Because the desert did not provide the necessary food items to endure particular seasons, the O’odham for example traveled up the mountain in winter to a permanent water source such as a spring. In the summer months, the people would travel to arroyo mouths where they would construct brush dams to prevent flood runoff from ruining their varieties of corn, melons, tepary beans, squash and other crops. Harvest would therefore run around October and November months that would typically
