For this reason, seaweed must grow near the ocean's surface -- within the reach of sunlight -- to survive, and there must be an abundance of carbon dioxide in the water. The sea water that provides seaweed with nutrients also carries bacteria, viruses, and fungi. Much like its land-based relatives, seaweed uses carbon dioxide to do its photosynthesis-thing. Seaweed, which originates from the ocean's garden, is one of the best materials for an earth garden. Sargassum, a type of seaweed that lives in the Sargasso Sea, has no holdfast, it simply floats in the water. Understanding how seaweed survives and grows is essential to protecting Earth's ecosystems. In other words, they photosynthesize. Apart from planting the seeds and ensuring the seaweed is in a clean environment, seaweed often does not need feed or additional attention. Here’s where our hero, seaweed, comes in. A … Like plants on earth use carbon dioxide and sunlight to produce oxygen for human beings to survive, seaweed use carbon dioxide in water and sunlight to produce carbohydrates for the marine life to survive.

Though kelp forests can be as high as 200 feet, some seaweed live in shallow tidal pools. Since it ‘breathes’ underwater, that CO2 gets pulled out of the ocean, helping to deacidify it. The wave energy and substrate of an area determine which seaweeds will grow there. There is sunlight under the sea to a certain depth and this is what seaweed use to grown (like Kat said). Sea urchins are like vacuum cleaners of the ocean floor. Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water. They can be filamentous algae, sheets or unicellular. Red algae seaweed, which can grow in the Dysphotic Zone, has a similar adaptation. And the more that’s pulled from the ocean, the more can be taken out of the atmosphere. Like those syst… Because of this, they must adapt to fluctuations in the temperature, currents and salinity of the water. They help to clean up any kelp that has fallen to the sea floor. Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of … Like all living things, seaweed needs to stay hydrated to survive. The spores then turn into sperm and eggs that join and form zygotes. That’s right—more than half of the oxygen you breathe comes from marine photosynthesizers, like phytoplankton and seaweed. Another technique, used to grow Sea Grapes or “Green Caviar”, is simply planting a cutting of seaweed (about 100g) into the seabed to help it take root. Seaweed, however, is not a true plant and does not use systems that can be waterlogged. Seaweed is actually a form of algae rather than a plant, and the name encompasses many species. The unicellular chlorophyta make up a large proportion of the global phytoplankton populations, the microscopic organisms that float with the currents throughout the sea. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Seaweed is the foundation of life for the entire ocean and provides most of Earth's oxygen.

As non-vascular plants, seaweeds lack the true leaves, stems, roots and internal vascular systems most other plants use to take in water, so they absorb it through the surface of their leaf and stem-like structures. Seaweed species that live at the ocean’s surface may also contain pigments that protect them from the sun’s ultraviolet light. For this reason, seaweed must grow near the ocean's surface -- within the reach of sunlight -- to survive, and there must be an abundance of carbon dioxide in the water. Fig. They help to clean up any kelp that has fallen to the sea floor. Some types of seaweed have adapted to brief dry periods when the tide is low. As a defense against these organisms, it is thought that seaweed synthesizes an arsenal of chemical compounds, and these in turn can be used by garden plants. Kelp thrives in cold, nutrient-rich waters. Seaweed is the common name for countless species of marine plants and algae that grow in the ocean as well as in rivers, lakes, and other water bodies. For every temperature and depth of water there’s a suitable variety that will naturally thrive. Since sea otters feed on sea urchins, they help to keep the sea urchin populations in balance and in return help to maintain a healthy kelp forest ecosystem. And there are about 30 different species of kelp in the world. To compensate for the dim light, red algae have a pigment called phycoerythrin.
