For example, a saltwater fish lives 3 in the ocean and a mouse is healthiest in a field. Certain organisms may be found in a large area, but they do not live in all of it. They are usually only found in a 4 part of it. This is the place where it is easiest for them to live. Ecologist call this place their 5 . They study the way organisms survive in their natural habitat.
