Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
Well when you perform this action you are using some percentage of the sunlight energy as you obtained it from a food that either came from a plant source or an animal source. Also plants are able to make their own food using sunlight i.e
Plants give energy to animals and animlas give energy to humans
or
Plants give energy to humans.
Hope this helps :).
