Ecosystem

 

 

 

1.                  Wetlands are complex ecosystems that provide spawning and nursery grounds for saltwater and freshwater fish, habitat for more than half of the migratory birds in the United States, and plants both exotic and commonplace. In addition to providing plant and animal habitat, wetlands play a crucial role in flood control and water filtration.

2.                  The Okavango River forms a vast wetland where it drains into the Okavango Delta in Botswana. Wetlands are complex ecosystems that provide spawning and nursery gounds for saltwater and freshwater fish, essential habitat for migratory birds, and plants both exotic and commonplace. Additionally, wetlands play a crucial role in flood control, nutrient cycling, and water filtration.

3. Terrestrial Biomes : North American ecologists refer to the world’s broad units of vegetation as biomes. Biomes include associated animal life, and are influenced by many factors, including latitude, altitude, moisture, and temperature. The major biomes use the dominant plant life for their names.

4. Tropical Rain Forest Distribution : Tropical rain forests are located near the equator where the temperature hovers around 27° C (80° F) year-round. Although they cover less than 10 percent of the Earth’s surface, tropical rain forests provide habitat for 50 to 90 percent of the world’s plant and animal species.

      5.    World Desert Regions : Most deserts arise due to atmospheric wind conditions. Warm air masses created two belts of desert, one along the Tropic of Cancer and the other along the Tropic of Capricorn. Other deserts result from the effects of ocean currents on landmasses, where cool air masses carry fog and mist, but little rain, along coastal regions.
