Answer:
Tropical rain forest
-luxuriant forest found in wet tropical uplands and lowlands around the Equator.
-Tropical rainforests, which worldwide make up one of Earth’s largest biomes (major life zones), are dominated by broad-leaved trees that form a dense upper canopy (layer of foliage) and contain a diverse array of vegetation and other life.
Coral Reefs
-coral reefs are large underwater structures composed of the skeletons of colonial marine invertebrates called coral.
-The coral species that build reefs are known as hermatypic, or "hard," corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies.
Mangrove Swamps
-Mangrove trees dominate this wetland ecosystem due to their ability to survive in both salt and fresh water. In the continental United States, only three species of mangrove grow: red, black, and white mangroves. Red Mangrove (Rhizophera mangle) is easily recognized by its distinctive arching roots.
-Black Mangrove (Avicennia sp.), which often grows more inland, has root projections called pneumatophores, which help to supply the plant with air in submerged soils.
