Ocean Food Chain | What Happens at the Bottom of the Ocean?

The ocean is full of different animals who form complex food webs with each other and the ocean. As you might know, the food chain is the place where each animal in an ecosystem falls in a linear position by links of who eats whom. We will be talking about how nutrients get transferred from one animal to another animal as a result of consuming prey.

Ocean food chain is very large and we can’t see it because it’s too deep. It consists of several axial zones – extending down to thousands of meters (or more) below the surface. The food web extends horizontally for thousands of meters above and below the water surface.

The ocean plays an immensely important role in the global food web. Marine life forms a significant amount of the biomass on Earth with exceptions due to plate tectonics. It is estimated that humans consume approximately 2.5 times the marine biomass as we consume terrestrial biomass, primarily in animal products like fish, crustaceans, and many other seafoods. In fact, nearly all of the world’s fish stocks are being fished to near exhaustion, with overfishing often leading to collapse of entire fisheries or stocks. A number of countries have recently implemented or are introducing specific management policies to tackle overfishing. Some have achieved this through sustainable harvesting practices while others rely on scientific management techniques.

Sustainable food is essential to a healthy planet. The oceans are depleted from over-fishing and pollution while aiming to feed an increasing human population in developing regions. In order to save this precious resource, it’s crucial for us to think about every choice we make about eating. What type of food do you eat? How do you eat? Can you grow your own food? Ocean Food Chain provides information about different food products/groups without necessarily claiming that they are the healthiest or most nutritious way to eat.
