approximately 400 km off the southeastern coast of Africa in the Indian Ocean. The rainforests of Madagascar are located in very humid‚ low-elevation‚ and narrow regional strips along the east coast of the island. The Madagascar rainforest is just another ecosystem‚ it actually acts as a home to many endangered species including the silky sifaka‚ sportive lemur‚ and the red-ruffed lemur. Another very important species that is indigenous to this rainforest is the rosy periwinkle‚ which is used to cure leukemia

agriculture can lead to desertification. Clearing forests removes the food‚ shelter‚ and other resources that forest dwelling organisms need to survive. Farming‚ logging‚ and road building‚ and other type of human land use and development often intrude into forested habitats‚ for example‚ breaking up a continuous expanse of forest into an array of fragments‚ or patches. Animals and plants adapted to unbroken forest will die out as a forest becomes fragmented. As habitat fragmentation proceeds

with Orang Asli and and their wise use of natural resources‚ we focused specifically on three major attributes‚ namely documentation of medicinal plants and knowledge of their use‚ traditional forest-related knowledge and conservation of natural resources. These attributes were broadly based on the ecosystem services identified in line with local and international policies‚ including the National Policy on Biological Diversity and CBD. The indigenous knowledge and practices on medicinal plants are

Worksheet Name __________________________________ Date ________ Period _______ Succession‚ a series of environmental changes‚ occurs in all ecosystems. The stages that any ecosystem passes through are predictable. In this activity‚ you will place the stages of succession of two ecosystems into sequence. You will also describe changes in an ecosystem and make predictions about changes that will take place from one stage of succession to another. The evolution of a body of water from a lake

to satisfy my requirement for a Natural Science class‚ however‚ this class has intrigued me and is more interesting than I expected. I have learned a lot about the environment‚ and I really enjoyed learning about ecosystems and the interaction between the biotic and abiotic of ecosystems. I found the earth’s major biomes particularly interesting‚ and would like to reflect on them. According to the text book‚ a biome is a large‚ relatively distinct terrestrial region with similar climate‚ soil‚ plants

of the interrelationships or interactions among the different components of the ecosystem. All the ecosystem components are directly and /or indirectly linked with one another. “There is constant interchange of various kinds within each system‚ not only between the organic and inorganic” (Tansley‚1935). The linking forces are two processes: the energy flow process‚ and the biochemical cycle. In other words‚ ecosystem components are linked to one another by the transfer of energy and nutrients via

The rain forest is an environment that is rainy and humid. The rain forest only has one season because it’s weather and temperature never change. The temperature never changes because of the high humidity rate and waters thermal resistance. The rain forest has direct sunlight that provides light and heat but indirect only provides light. Rain forests have an average temperature of 80 degrees fahrenheit. The temperature may feel hotter due to the high humidity rate. Rain forests can receive

Ecosystems are environments where biotic (living) organisms and abiotic (non-living) components interact together to create a functional‚ complex network of nutrient and energy cycling. These balanced environments take time‚ sometimes many years‚ to develop. During the course of development‚ species are replaced by other species within the ecosystem‚ a process known as succession. Primary succession happens when species grow in locations where organisms have never previously existed. Secondary succession
