Tropical rainforests are found in locations such as:- Central America- West Africa- Eastern Madagascar- Indonesia- Malaysia- West Coast of India- Papua New Guinea- USA- Congo- AustraliaVARIOUS MUTUALISTIC RELATIONSHIPS WITHIN THE TROPICAL RAINFOREST:A mutualism is a relationship where both species help each other live or live as one.This way its easier to navigate a predator, or look for prey.The species involved are called symbionts. Detritivores and decomposers reintroduce vital elements such as carbon, nitrogen, phosphorus, calcium, and potassium back into the soil, allowing plants to take in these elements and use them for growth.
