Intertidal zones of rocky shorelines host sea stars, snails, seaweed, algae, and crabs. Barnacles, mussels, and kelps can survive in this environment by anchoring themselves to the rocks. Barnacles and mussels can also hold seawater in their closed shells to keep from drying out during low tide.

How does seaweed get its energy?

Oxygen Production. 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.

What does seaweed eat?

Seaweed absorbs minerals and nutrients from the sea. If the surrounding water contains these metals, the seaweed will absorb them as well.

How does seaweed get water?

Water and Nutrients

All parts of a seaweed touch the water, so it doesn't need an internal conducting system like land plants do; they absorb what they need directly from the water through surface tissues. Thus, the water around seaweed needs to continually move, bringing in fresh supplies of nutrients and gasses.

How does seaweed survive in saltwater?

Hydration. Like all living things, seaweed needs to stay hydrated to survive. 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.

How does a seaweed adapt to its environment?

Seaweeds have small blades that are called fronds. ... This is helpful for seaweeds because it gives them more surface area to gather sunlight and produce food. Fronds of seaweeds are very tough, and this is helpful for the plant's survival. This toughness allows the seaweed to avoid being torn by strong ocean waves.

Is seaweed endangered?
