Aceson Aw index 1 ( HBL 24 may )

2) Human activities such as deforestation, will affect the Allomerus decemarticulatus - Hirtella physophora symbiosis as both species are native to Amazon and the worker ants only inhibit in Hirtella physophora, and no other plants, deforestation of the Amazon, will eventually lead to lesser of these species of plants. Once it is extinct, the Allomerus decemarticulatus will surely be extinct too.
3a) Mutualism: The (Allomerus decemarticulatus - Hirtella physophora) relationship is an example of mutualism. This species of worker ants only inhabit specifically in Hirtella phsophora . They seem to have taken advantage of the shelter and food(nectar), which the plant have provided for them, which is in fact simple parasitism. However, the plant also benefits greatly as the workers, with the help of traps and predation, defend the plant against parasitic insects and plants.
Commensalism : ( Mould - Allomerus decemarticulatus),the relationship between the two organisms depict commensalism as these ants benefits from its trap during predation, and they ut in place the mould into tiny holes of the traps so as to reinforce the trap. However, the mould does not have any significant benefits and continue to grow as per normal.
Predation: (- Allomerus decemarticulatus- parasitic insects), this explotative relationship can be considered as predation for the ants prey on the parasitic insects and kill them. The ants lay in ambush in the holes of the traps and grab hold of the insects, other ants would sting venom in the prey. This is beneficial to the ants but not to the insects.
3b) example for mutualism: (clownfish and sea anemone) the clownfish seeks shelter in the sea anemone to avoid from its predators as the tentacles of the sea anemone have a stinging mechanism which the clownfish is protected from due to a layer of mucus on them. While the clownfish protects the sea anemone from its predators.
Example for commensalism : ( barnacles and crabs) , barnacles feed on plankton and detritus on the shell of crabs before finding another good sources as the crab moves from one place to another. The crab remains unaffected.
Example of predation: (Cheetah Thompson Gazelle), the cheetah preys on Thompson Gazelle which results in the death of the prey, thus making is a form of predation, where the weaker ones get hunted
