Lack of Resources
At this depth, there is not enough light for photosynthesis to occur and not enough oxygen to support a fish with a high metabolism. To survive, creatures have much slower metabolisms and therefore can survive using less oxygen. They can also go for months 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.

Famous quotes containing the words lack of, lack and/or resources:
“It is perfectly right for a gentleman to say “ladies and gentlemen,” but a lady should say, “gentlemen and ladies.” You mention your friend’s name before you do your own. I always feel like rebuking any woman who says, “ladies and gentlemen.” It is a lack of good manners.”
—Susan B. Anthony (1820–1906)
“The anorexic prefigures this culture in rather a poetic fashion by trying to keep it at bay. He refuses lack. He says: I lack nothing, therefore I shall not eat. With the overweight person, it is the opposite: he refuses fullness, repletion. He says, I lack everything, so I will eat anything at all. The anorexic staves off lack by emptiness, the overweight person staves off fullness by excess. Both are homeopathic final solutions, solutions by extermination.”
—Jean Baudrillard (b. 1929)
“Parents can offer their help by suggesting and locating resources likely to be unfamiliar to children, such as people, books, and materials that can be useful.”
—Dorothy H. Cohen (20th century)
