HBL learning by Chenming

2.How has/will human activities in the Amazon regions affect the Allomerus decemarticulatus ants?
Deforestation will decrease the number of trees in the region causing many animals to be homeless. if the trees are gone, the Amazonian tree ants will not have a shelter. since the ants depends on the trees in order to catch preys, without the trees, the ants will find it difficult to hunt and ultimately decrease its number.
3a From the extract, identify the different symbiotic relationships and cite the organisms involved.Clue: There are at least 3 types of relationship.
Mutualism, the ants and the trees both benefits.
predation. the ants and its preys.
Commensalism. the ants uses hair from the stem.
3b.For each type of relationship you have identified in (a), name another example of a pair of organisms depicting that relationship in nature.
mutualism. clown fish and sea anamone.
predation. lion and giraffe.
commensalism. orchids grow on tree trunks.
