In a soft-bottomed intertidal community, oxygen would be most plentiful for meiofauna in which type of bottom?

The options are:

A. Gravel

B. Sand

C. Silt

D. Clay

E. Mud

The answer is A. Gravel

Explanation:

Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.

Gravel aren't tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
