Document Summary
The loss of beluga population and impact on the environment. The overall food cycle would be impacted in terms of predator and prey. Definition of ecology: the scientific study of the abundance and distribution of organisms in relation to other organisms and environmental conditions. We can study ecology at different hierarchal levels. Embedded in communities- multiple populations- interaction among species. Ecosystems are made up of range of communities. Individual- survival and reproduction the unit of natural selection. Scale becomes bigger in terms of spatial and temporal. Scale has to be a consideration when choosing the hierarchal levels: it depends on the type of question and at what hierarchal level you are trying to study. If it doesn"t support the hypothesis- can not prove the hypothesis a: should always prove the hypothesis, gather data that supports or does not support the hypothesis. The second one is better: links everything together, it is more complex and more realistic.
