Kelp and Algae
Kelp and algae play a vital role in the ocean's ecosystem, providing a primary food source for the ocean and also producing a large percentage of the oxygen in the atmosphere. Kelp is a form of macroalgae that clings to rocks in the ocean, and is a higher form of plant than algae.
Seaweed lacks a root system, instead floating in the ocean and absorbing nutrients. However, like other plants, seaweed absorbs sunlight and gains energy through photosynthesis.
