WebThe ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it. At great depths, light is so scattered that there is nothing left to detect. Only the very top layers of the ocean get enough light to support plants, and ... WebOcean planets where nutrients on the sea floor are far away from sunlight at the surface do not lend themselves well to large, complex life forms, as shown by how reliant deep sea life is on energy from surface ecosystems. So, it is reasonable to assume intelligence requires surface life (either atop the sea or on land).

WebThey discover the characteristics of deep-sea extremophiles that help those organisms survive in several deep-sea ecosystems. ... we know that life can occur without light, and many ecosystems are supported in ways other than plant-based photosynthesis. For example, hydrothermal vents are based on chemosynthesis, in which organisms get their ...

WebSep 8, 2024 · How deep can photosynthesis occur in the ocean? Below a depth of about 660 feet (200 meters), not enough sunlight penetrates to allow photosynthesis to occur. The area of the ocean where photosynthesis occurs is known as the euphotic zone (meaning “good light”). WebStudy with Quizlet and memorize flashcards containing terms like When new marine phytoplankton biomass is produced by photosynthesis, dissolved carbon dioxide is converted to, Greater mixing and nutrients from the land cause the coastal areas to generally have higher primary productivity than the open ocean., The upper boundary of … WebHow does ocean depth affect photosynthesis? As depth increases, light intensity decreases until there reaches a depth where photosynthesis can no longer occur (Figure 7.3. 1). The region through which sufficient light for photosynthesis can penetrate is called the photic or euphotic zone, which extends down to about 200 m (section 6.5). greater than london
