3. Why is rainforest known as the lungs of the earth

4. What are coral reefs?

1. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

2. An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.

3. Amazon rainforest is the most biodiverse region on earth, providing shelter to three million species on plants and animals. Billions of trees absorb tons of carbon dioxide every year and slow down the climate change along with producing 20% of earth's oxygen, hence named 'Lungs of Earth.

4. A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. ... Most reefs grow best in warm, shallow, clear, sunny and agitated water.
