Sugar kelp


Young plants secrete mucus and other substances that smell and taste bad. Animals and algae therefore have difficulty attaching to the slippery surfaces. The alga produces a chemical pesticide to keep intruders at bay.
   On the other hand, older plants quite often have other plants growing on them, mostly sea-mats, hydroids and fine threaded algae. Animals and algae shade the plants and make it more difficult to absorb sunlight for photosynthesis. It is possible to say that it starves as it cannot absorb enough light to produce energy rich compounds.

Blown asunder

Sugar kelp can normally be as old as 3 years. They usually die during a storm when the waves have ripped the plant loose from its foundation. If animals, like the kelp limpet or sea-urchin have eaten parts of the root system or stalk, it easily torn loose in the waves. Even bacteria can feed on older plants. Bacteria can be eaten by small animals, and in turn became food for larger animals.
