Photosynthesis organisms occur at different depths in the ocean. Do they receive qualitatively and quantitatively the same light? How do they adapt to carry out photosynthesis under these conditions?

Answers (1)

Light saturation takes place at a 10 percent level of complete sunlight. Therefore, light energy is rarely considered to be a limiting factor during the process of photosynthesis. Photosynthetic plants in the deep ocean are supplied with enough light energy to carry out the process of photosynthesis effectively. Furthermore, the plants showcase a variation of the constituent pigments. These pigments ensure that photosynthesis occurs in different light presences.

Adaptations for Photosynthesis:

1. Efficient Light Capture: Many organisms form specialized light-harvesting complexes to optimize energy absorption in low-light conditions.

2. Structural Adaptations: Certain photosynthetic organisms, such as phytoplankton, are microscopic and remain near the surface to capture more light. Others regulate their buoyancy to position themselves effectively within the photic zone.
