Final answer:
The population distribution observed in this scenario is clumped, as tree-dwelling primates group together in specific territories.
Step-by-step explanation:
In this scenario, the type of population distribution observed is Clumped.
In a dense rainforest, tree-dwelling primates tend to group together in specific territories. This clustering occurs due to the availability of resources in certain areas, such as food and shelter.
An example of clumped distribution in a rainforest could be seen with how monkeys gather around fruit-bearing trees, forming distinct groups within the forest.
