Answer:

Tropical rainforest-Rainforests are natural air filters. They store and filter excess carbon and other pollutants from the atmosphere and release oxygen through photosynthesis. Without rainforests, our planet is unable to mitigate excess greenhouse gas emissions, which destabilizes the Earth's climate.

Coral reefs-Coral reefs protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many Marine organisms. are the source of nitrogen and other essential nutrients for marine food chains.

Mangrove swamps-The dense root systems of mangrove forests trap sediments flowing down rivers and off the land. This helps stabilizes the coastline and prevents erosion from waves and storms. By filtering out sediments, the forests also protect coral reefs and seagrass meadows from being smothered in sediment.
