2) Human activities in the Amazon Rainforest, such as the cutting down of trees and clearing areas in the rainforest for plantations, has caused the number of trees available for habitat of the ants to be reduced. Thus, the ants will be unable to find a habitat to live in. The ants also uses a unique way of capturing their prey: cutting hairs from the stem of the plant they inhabit, and use the tiny fibers to build a spongy platform, and the structure is glued together with a protein that comes from chewed and regurgitated vegetation. The decrease in the number of trees will also render the ants being unable to use this method to capture their prey, as they are unable to obtain the hairs from the plant in which they live easily.

3a) Commensalism: allomerus decemarticulatus ants and the tree in which they live in.
Predation: allomerus decemarticulas ants and their prey.
Parasitism: ( caused by allomerus decemarticulas ants) fungus and rainforest tree.

 b) Commensalism: Epiphytes and fern
Predation:Tiger and zebra
Parasitism: Tree-ear fungus and tree
