Phytoplankton Food Chain In The Ocean

They grow by taking nutrients from water and used as food by zoo-plankton here Krills which are called primary consumers.

Phytoplankton food chain in the ocean. A food web is a system of interconnected food chains. Like land plants they take up carbon dioxide make carbohydrates using light energy and release oxygen. Phytoplankton Food Chain In The Ocean.

Phytoplankton are on the bottom of the aquatic food chain so their nourishment and population growth are essential to other creatures from the small fish that eat them to larger fish and eventually humans. Phytoplankton are the marine plants that grow most in the sunlit surface ocean. Phytoplankton is the primary producer at the base in all types of water bodies particularly in the oceans.

They also provide the primary food source for the zooplankton and together form the base of the oceanic food chain. But environmental changes and human activities may be threatening plankton - and therefore all. These small plants are very important to the ocean and to the whole planet.

Food chains are natures way of transferring energy between different species. Small fish and invertebrates also graze on the plant-like organisms and then those smaller animals are eaten by bigger ones. Phytoplankton has declined 40 in 60 years as figures reveal Earth has been getting hotter since the Eighties.

Similarly when there are not enough phytoplankton to make food or if the wrong types of phytoplankton grow the food chain of the sea can collapse turning the ocean into a watery desert wasteland. How we humans manage to put ourselves into both marine and land food chains and other extraordinary truths revealed. Phytoplankton are microscopic marine algae.

Phytoplankton is microscopic plants that live in the ocean seas or lakes. Also some types of algae seaweed unicellular plants bacteria etc. Microscopic marine algae which form the basis of the ocean food chain.
