<P> At this depth , there is not enough light for photosynthesis to occur and not enough oxygen to support animals with a high metabolism . To survive , creatures have slower metabolisms which require less oxygen ; they can live for long periods without food . Most food either comes from organic material that falls from above or from eating other creatures that have derived their food through the process of chemosynthesis ( the process of changing chemical energy into food energy ) . Because of the sparse distributions of creatures , there is always at least some oxygen and food . Also , instead of using energy to search for food , these creatures use particular adaptations to ambush prey . </P>
