A poster explaining Marine Ecosystems.
Information on poster:
Marine waters cover two thirds of the Earth’s surface, making them very important to the health of both aquatic and terrestrial environments. Phytoplankton perform about 40% of all the photosynthesis that occurs on the planet and are very important to the food chain. Deeper down in the ocean, where there is no light from the sun, lots of naturally occurring minerals exist, including silver, gold, copper, manganese, cobalt and zinc.
