Why does photosynthesis occur in oceans?
Just like plants on land, ocean-going plankton need light from the sun to prosper and grow. But light is absorbed by ocean water — and some colors of light are absorbed more readily than others. That’s why nearly all photosynthesis in the ocean takes place in the sunlit upper layers.
What does phytoplankton do for the ocean?
Phytoplankton provide organic matter for the organisms that comprise the vast majority of marine life. They do this by consuming carbon dioxide that would otherwise dissolve in the sea water and make it more acidic. The organisms provide organic matter for the vast majority of the marine food chain.
What are the producers in the ocean?
The primary producers of the ocean are microscopic phytoplankton, including protists like algae and diatoms. The majority of marine consumers are planktonic, including protists and small animals. Most decomposition is carried out by species of bacteria, enabling nutrients to cycle back to producers.
What are 5 consumers in the ocean?
Primary consumers in the ocean include zooplankton, small fish, and crustaceans. The secondary consumers are fish, coral, penguins, whales, and other species that eat the zooplankton. The top predators in the ocean, sharks, killer whales, and leopard seals, eat both primary and secondary consumers.
What are 6 different producers in the ocean?
Primary producers
- Phytoplankton form the base of the ocean foodchain.
- Phytoplankton.
- Dinoflagellate.
- Diatoms.
Where does energy in a food chain come from?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Where is a jellyfish in the food chain?
Jellyfish play an important role in the oceanic food chain and the ecosystem. Jellyfish are carnivorous and feed mostly on zooplankton, comb jellies and other jellyfish. Large species of jellyfish feed on large crustaceans and other marine organisms. Sea turtles, sunfish and spadefish prey upon jellyfish.
What does a food chain show and why is it important?
A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.
