A biosphere reserve is an area of land or water that is protected by law in order to support the conservation of ecosystems‚ as well as the sustainability of mankind’s impact on the environment. This means that each reserve aims to help scientists and the environmental community figure out how to protect the world’s plant and animal species while dealing with a growing population and its resource needs. These areas were created by the United Nations Educational‚ Scientific‚ and Cultural Organization

agricultural or horticultural purposes. An invasive plant is one that is established‚ then expand and reproduce on their own (Forest Management). This means that they have the ability to compete with native species and other native plant communities. Non-native invasive species affect natural ecosystems negatively by completely taking over all other plants. This can unbalance the ecosystem and harm animals as well as nearby plants. They can also spread exotic diseases to other plant life. 46% of the federally

Within any community some species may become less abundant over some time interval‚ or they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". Some specific examples of observable succession include: 1. The growth of hardwood trees

Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example‚ after a wildfire)‚ or even millions

called a food chain. Let us make this point more clearly by taking the example of a simple food chain operating in a grassland or forest. In a grassland or forest‚ there is a lot of grass (which are green plants). This grass is eaten up by animals like deer. And this deer is then consumed (eaten up) by a lion. This simple food chain operating in a grassland or forest can be represented as: Grass --> Deer -->Lion (Producer) (Herbivore) (Carnivore) This food chain tells us that grass is the starting

The rain forest has large amounts of rain because it is very hot and wet. Tropical rainforests are defined by rainfall. They would not survive without it. Not all rain forests have tropical sunny

The main biomes are Marine‚ Tundra‚ Desert‚ Savannah‚ Grassland‚ Tropical Rain Forest‚ Deciduous Forest‚ and Coniferous Forest. 4. What is an ecosystem? An ecosystem includes all the abiotic factors in addition to the community of species that exists in a certain area. Human populations depend on plants and animals for much of their food‚ medicines‚ clothing‚ and shelter. Perhaps even more important‚ intact ecosystems perform many vital functions‚ like purifying the air‚ filtering harmful substances
