Red algae thrive in deep ocean regions by utilizing phycoerythrin to absorb blue light, reflecting red light. Adaptations in aquatic ecosystems enable survival without light through photosynthetic adaptations and energy extraction from inorganic sources.
Red algae in deep oceans synthesize their food by utilizing phycoerythrin in their chloroplasts to absorb blue light, which penetrates deeper into water, while reflecting red light.
Adaptations have evolved in aquatic ecosystems to enable living things to survive without light, such as having photosynthetic tissue near the water surface or extracting energy from inorganic chemicals in environments like hydrothermal vents.
These strategies allow red algae to thrive in deep ocean regions where sunlight is limited, showcasing their unique ability to harness light energy for photosynthesis.
