The bullhorn acacia is a type of tree in which acacia ants live in its hollow thorns. The ants defend the acacia from predation and the acacia tree provides the ants with high nutrient nectar. This relationship show which type of symbiosis?

Mutualism

Explanation:

Organisms of same or different species tend to interact in their natural environment. They form relationships that benefits or harms them. The relationship between two organisms is referred to as SYMBIOSIS. A type of symbiotic relationship is one in which both organisms involved benefits from the relationship. This kind of symbiotic relationship is called MUTUALISM.

This mutualistic relationship is the case here, where both the bullhorn acacia tree and acacia ants provide services that benefits both organisms. The acacia tree houses the acacia ants, providing them with shelter and food in form of highly nutritious nectar and in return the acacia ants protect the tree by helping drive away predators or herbivores.

explanation:

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
