Feeding the Deep Ocean

Dr Anjani Ganase, marine ecologist, considers the natural progression of a dead whale in the ocean. Scientists are discovering that the impacts of “whale falls” continue for decades and even centuries. The sun supports all life on our planet, well nearly all life. Animals depend on plants to create food through photosynthesis (the process by which plants harness sunlight and water to create sugar). Plant life is the foundation of the global food web. Consider that 70% of the planet is ocean, and 90% of the ocean is deep ocean which is deeper than 1000 m (average depth of the ocean is more than 3600 m). Any ocean beyond 1000 m depth is beyond the penetration of sunlight, and photosynthesis does not occur at depths below 200 m. Does the sun support life, even in the deepest darkest part of our oceans? Life in the deep seas persist. In such a nutrient desert, life exists as a result of several adaptations, including having low metabolism, gulping and feeding...
