2) Human activities in the Amazon regions would affect the Allomerus decemarticulatus ants. An example is deforestation, these forestland are being converted and being used for other purposes. The trees there are being cut down so that the land could be used, however, as shown in the TODAY article, the Allomerus decemarticulatus ants cut hairs from the stem of the plant they inhabit, and use the tiny fibers to build a spongy platform, which would then be reinforce to be used as a trap. When all the trees are being cut down, the ants will no longer have the resources to build their traps to capture their prey for food, thus this shows that human activities in the amazon forest would cause harm to the ants.

3a) Allomerus decemarticulatus worker ants cut hairs from the stem of the plant they inhabit, and use the tiny fibers to build a spongy platform(Allomerus decemarticulatus worker ants and plant)- Commensalism

Swarms of workers then rush over the hapless prey, stinging it into submission. The prone insect is then carted off towards the ants' home, a leaf pouch, where it is carved up.( worker ants and prey)-Predation

The structure is glued together with a protein that comes from chewed and regurgitated vegetation. The ants make holes in the platform and put in place pieces of sooty mould, which quickly grow around the structure and reinforce it.(mould and ants)-mutualism

3b)Commensalism- The cattle egret forages in fields among cattle and horses, feeding on insects stirred up by the grazing animals. The egret benefits from this relationship, while the livestock are typically unaffected by it.

Mutualism- The clownfish feeds on small invertebrates which otherwise potentially could harm the sea anemone, and the fecal matter from the clownfish provides nutrients to the sea anemone. The clownfish is additionally protected from predators by the anemone's stinging cells, to which the clownfish is immune.

Predation-Cheetah feeds on the Thompson Gazelle for food.
