The ants live inside inflated thorns at the base of leaves of some species of Acacia trees.
The ants defend the plant from predators - and the plant produces sugars to feed the ants.
Nigricep ants live in the live in the whistling thorn acacia in the Savanna. They do this to help them survive. The whistling thorn acacia provides the ants with food during dry periods and shelter during rainy periods.
I can think of no better example than acacia trees and acacia ants. The tree has special chambers for the ants to live in and it has special growths specially made for feeding the ants.
Predators are less likely to eat ants that live in acacia trees because these ants have a mutualistic relationship with the tree, which provides them with shelter and food in the form of nectar and protein-rich Beltian bodies. In return, the ants protect the acacia from herbivores and competing plants. Additionally, the aggressive behavior of these ants, along with their ability to deliver painful stings, deters potential predators from attacking them. This mutualism creates a protective environment for the ants, making them less vulnerable to predation.

If the ants were removed from the acacia tree the trees would be stripped of their leaves by elephants. The ants serve as a defense mechanism for the trees.
yes
In the mutualistic relationship between thorn acacia trees and acacia ants, the acacia tree provides shelter and food (nectar and protein-rich Beltian bodies) to the ants, while the ants protect the tree from herbivores and competing plants. However, if the relationship becomes imbalanced, the acacia tree can be harmed if the ants become overly aggressive, attacking beneficial insects or even larger organisms that do not threaten the tree. Additionally, if the tree's growth is stunted or compromised, it may not produce enough resources for the ants, leading to a decline in both populations.
They have a mutual relationship. At the base of the thorns of the acacia tree there are hollow lumps which the ants can turn into a hive. When animals, such as giraffes, start to eat the soft acacia leaves it vibrates the stems and the ants come out and attack the intruder annoying the giraffe so much that it stops eating at the acacia and moves on to find a less irritable meal. The tree then repays the ants by giving off a sweet nectar that the ants use to feed to there larvae. The ants also patrol down and around the base of the acacia and not eat but chew and destroy any other alien saplings growing in the vicinity of the acacia (not using a single bit of the destroyed plant). It is almost as if the ants know they are helping the acacia dominate and get as much water as possible.
