Answer:
What is an Ecosystem? What are examples of Diverse Ecosystem?
- The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment. An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.
What is a Rainforest? Why is Rainforest known as the lungs of the earth?
- Rainforests are forests characterized by high and continuous rainfall, with annual rainfall in the case of Tropical Rainforests between 2.5 and 4.5 metres and definitions varying by region for temperate Rainforests. Tropical Rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies hugely with year-to-year variations in the climate.
What are the major parts of the Rainforest? Describe each
What are the different layers of a Rainforest Called?
- Emergent Layer - very sunny because it is the very top.
- Canopy Layer - much of the rain is stopped by the thick foliage.
- Understory Layer - many vines, dense vegetation, not much light.
- Forest Floor - dark, damp, full of many dead leaves, twigs and dead plants.
What are coral reefs? Where are they found? Why are they important to marine lives?
- A coral reef is an underwater ecosystem characterized by reef-building corals. Coral reefs are found in more than 100 countries around the world. Most reefs are located between the Tropics of Cancer and Capricorn, in the Pacific Ocean, the Indian Ocean, the Caribbean Sea, the Red Sea, and the Persian Gulf. Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.
What are the different types of coral reefs. Describe each
The three main types of coral reefs are fringing, barrier, and atoll.
Fringing reefs grow near the coastline around islands and continents. They are separated from the shore by narrow, shallow lagoons. Fringing reefs are the most common type of reef that we see. Barrier reefs also parallel the coastline but are separated by deeper, wider lagoons.
Barrier reefs are similar to fringing reefs in that they also border a shoreline; however, instead of growing directly out from the shore, they are separated from land by an expanse of water. This creates a lagoon of open, often deep water between the reef and the shore.
When a fringing reef continues to grow upward from a volcanic island that has sunk entirely below sea level, an atoll is formed. Atolls are usually circular or oval in shape, with an open lagoon in the center.
