Sagot :

Answer:

1. An Ecosystem is a biological community of interacting organisms and their physical environment.  

Some Example: Deserts.

Forests.

Large marine ecosystems.

Marine ecosystems.

Old-growth forests.

Rainforests.

Tundra.

Coral reefs.

2. A Rainforest can be described as a tall, dense jungle. The reason it is called a "rain" forest is because of the high amount of rainfall it gets per year.

Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen.

3. emergent, canopy, understory, and forest floor.

Emergent: The top layer of a rain forest is called the emergent layer. This layer receives bright sunlight and plenty of rain, and is also very windy.

Canopy: Canopy Layer. Beneath the emergent layer is the canopy, a deep layer of vegetation roughly 6 meters (20 feet) thick.

Understory: Smaller trees grow in patches of sunlight. These plants provide food and shelter for small animals and birds, as well as larger predators that live in the trees.

Forest Floor: Rain forests are divided into layers or stories. The forest floor is the lowest layer where it is dark, hot, and damp. Only two percent of sunlight gets through the thick canopy trees and understory plants to reach the forest floor.

4. a ridge of rock in the sea formed by the growth and deposit of coral.

Corals are found all over the world's oceans, from the Aleutian Islands off the coast of Alaska to the warm tropical waters of the Caribbean Sea

Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast
