Why is organization important to the study of ecology?
Levels of organization helps us (people) to classify the different types of interactions that occur in the environment.
There are six different levels of organization important to the study of ecology - they are: species, population, community, ecosystem, biome and biosphere.
By understanding these relationships we can make informed decisions about policy regarding how to manage our wildlife resources.
For example, Isle Royale is an island located in Lake Superior close to Minnesota which was turned into a national park in the 1930's. The island has a population of moose and wolves. The populations of wolves have dropped to only 3 in 2015 and the number of moose have increased greatly.

By understanding the biology of the moose (species/population level), their predator-prey interaction with wolves (community level) and biotic/abiotic factors (ecosystem level) the park service can make better decisions about how to best manage wildlife populations if the wolves on the island die out.
Here is a review of levels of organization in ecology.
