Answer:
Plants absorb energy from sunlight, take in carbon dioxide from the air through their leaves, take up water through their roots, and produce glucose and oxygen.
Step-by-step explanation:
- Seaweeds get their food through the process of photosynthesis, which uses energy from the sun to convert carbon dioxide into organic molecules, and produces the by-product oxygen. “Seaweed” is the common name for countless species of marine algae that grow in the sea. They produce oxygen by photosynthesizing energy from the sun, just like plants do on land.
- They are a bit like photosynthetic plants, but instead of using energy from light (like plants do to make food from carbon dioxide), they use energy from chemicals present in the cold seeps and hydrothermal vents. Tubeworms use hydrogen sulfide as an energy source, which is the same chemical emitted by a rotten egg. They are one of the few creatures on Earth that do not need to rely on the Sun for energy. Tubeworms take up sulphide from the sediments through root-like structures, which are at least as long as the tube projecting above the ocean floor.
