At what level of organization would a scientist study the interaction between seals and polar bears in the arctic? Explain your answer.

When a set of any species or organisms lives in an area for longer time, they are called as population of that area and if a group of population of different kinds living and interacting with each other in a region, it is called community. Similarly in the same way the study of the interaction between seals and polar bear in the arctic region will be a community.
