1.) An ecosystem is a community of living and non-living things that work together – it consists of abiotic (soil, water, air) and biotic parts (flora, fauna).

The examples of diverse ecosystem are Forests, desert, grasslands and streams.

2.) Rainforests are a kind of forest habitat.

They are found in warm places, and are full of many tall trees and leafy plants. It's called "rainforest" because it also gets a lot of rain every year, helping all the plants grow.

Rainforests are often called the "lungs of the planet" for their role in absorbing carbon dioxide, a greenhouse gas, and increasing local humidity.

3.) MAJOR PARTS OF THE RAINFOREST :

  • Canopy Layer - much of the rain is stopped by the thick foliage.
  • Understory Layer - many vines, dense vegetation, not much light.
  • Emergent Layer - very sunny because it is the very top. Only the tallest trees reach this level.
  • Understory Layer - many vines, dense vegetation, not much light.

4.) A coral reef is an underwater ecosystem characterized by reef-building corals.

  • Coral reefs are found in the deep sea away from continental shelves, around oceanic islands and atolls.
  • They reduce damage in the event of storms, hurricanes and other cyclones, as well as, to some extent, the energy of tsunamis.

5.) DIFFERENT TYPES OF CORAL REEFS

  • Barrier reefs are similar to fringing reefs in that they also border a shoreline.
  • Fringing reefs are reefs that grow very close to the shore on mainland or high island
  • Patch reefs are small, isolated reefs that grow up from the open bottom of the island platform or continental shelf.
  • An atoll is a ring-shaped coral reef, island, or series of islets.

Answer:

1. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Grasslands, tundras, deserts, rainforests, terrestrial and marine ecosystems, are some examples of ecosystems that are diverse and contribute a lot to creating a well-balanced environment.

2. 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.

3. Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.

4. 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.

5. The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands.
