HBL LSS Homework by Hu Zhanpeng

How has/will human activities in the Amazon regions affect the Allomerus decemarticulatus ants?
The amazon forest has been used for industrial purposes like deforestation etc. By doing so, the ants would be unable to feed on other insects for food as they need the fibers etc.from the plant to construct the trap to trap insects. Also, their habitat will be devastated too. Without plants to construct traps for food, these ants would have no food to feed on, and have a higher percentage to be captured and eaten by other predators.
Also, with the effects of global warming and deforestation, insects will go under grass to gain more shades. This makes it easier for the ants to trap insects as as a shorter time will be acquired for it to trap insects.
From the extract, identify the different symbiotic relationships and cite the organisms involved. Clue: There are at least 3 types of relationship.
Commensalism: The ants cut hairs from the stem of the plant they live in to construct their traps.
Predatory: The Allomerus decemarticulatus ants kill and eat the insects trapped by the trap made by the ants.
Parasitism: The ants farm the fungus for protein from the fungus and the plant.
For each type of relationship you have identified in (a), name another example of a pair of organisms depicting that relationship in nature
Commensalism: Remora and Shark
Predatory: Cheetah and Thompson Gazzele
Parasitism: Tree-Ear Fungus and Tree.
