The photograph shows rockweed. Which feature allows rockweed to withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis

B

Explanation:

This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action

The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.

It is a brown alga and grows in the rich intertidal zone.

The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.

Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.

The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.

Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.
