<span>Deep ocean minerals are mineral nutrients that are mined from
deep ocean water found at ocean pits of between 250 and 1500 meters. It encompasses
over 70 mineral nutrients and trace elements as well as magnesium, calcium and potassium in their bio ionic
form.</span>
The two types of solid structures made by marine animals from minerals that they extract from seawater are shells and coral reefs.
Shells are hard, calcareous organs present on the outside of the shellfish's body. As mollusks do not have bones inside the body, the shells have the function of ensuring the protection of the body of these animals.
Coral reefs are formations constructed from the deposition of calcium carbonate by various marine organisms, mainly corals, but other organisms such as calcareous algae and molluscs also contribute to the formation of reef substrates. Corals are small and very fragile Anthozoa class cnidarian animals that use calcium carbonate from the water to build a hard exoskeleton.
Single celled or unicellular organisms use simple processes such as diffusion and active transport to gain nutrients. iii) Unicellular organism requires less energy and makes use of simple process such as diffusion to perform gas exchange.
