(01.03 hc) based on your knowledge of ocean chemistry, predict the feeding mode and size of organisms found in the deep layers of the ocean, and select the best explanation. non-photosynthetic because very little light is available; small because there are so few nutrients photosynthetic because light is available; large in order to eat other organisms photosynthetic because light is available; small because there is little dissolved oxygen non-photosynthetic because no light is available, large in order to tolerate low salinity

The answer is Non-photosynthetic because very little light is available; small because there are so few nutrients.

Explanation:

Very little to no light reaches below 200 m, but below 1000m it's completely dark. Therefore, photosynthesis is impossible, autotroph organisms depend on organic matter and they obtain energy through chemosynthesis. Most organisms are small and passive, they don't waste energy in hunting, but they wait for the food to reach them. Although there's a condition called deep-sea gigantism, it's due to the high pressure and not to the low salinity. These gigantic organisms are mainly composed of water and that way they avoid being compressed, like organisms with air cavities like humans.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
