9. Oyster populations are primarily, if not exclusively, composed of _____.

Adults, Young oysters have a very high mortality rate; older oysters have a much lower mortality rate. Thus, most oyster populations consist primarily of older individuals.

Grasses, like oysters, have a relatively high mortality rate early in their life span, after which the mortality rate decreases.

Robins, The mortality rate of robins remains relatively constant throughout their life span.

None of these
