How does kelp adapt to their environment?

Although kelps resemble land plants they are uniquely adapted to life in cool clear moving water. They depend on moving water to provide a steady supply of nutrients for photosynthesis. As water flows by the blades their serrated edges help to increase water mixing.

How is algae adapted to its environment?

How does phytoplankton adapt to its environment?

Phytoplankton have special adaptations to stop them from sinking to the bottom to die. Because phytoplankton are tiny they don’t weigh very much and they have a large surface area relative to their volume which helps them float.

How does seaweed absorb nutrients?

How do fungi adapt to their environment?

Fungi have adapted over the years in response to their environment. One way in which they have adapted is by increasing their surface area of their gills. … Overall the fungi have adapted stronger and thicker cell walls made out of chitin. This allows for extra support and also protection from predators.
