The distribution of the infauna of soft-bottom subtidal communities is often closely related to:

Question

Quizplus · Accepted Answer

The particle size of sediment is a key factor that shapes the infaunal community in soft-bottom subtidal habitats. Different infaunal species have adaptations to different sizes of sediment particles, and changes in sediment particle size can drastically affect the composition and abundance of infaunal species.

Answer: A and C
 Temperature and salinity are also important factors that can influence the distribution of infaunal species in soft-bottom subtidal habitats. Infaunal species have optimal temperature and salinity ranges, and changes in these parameters can cause shifts in the community structure. However, while these factors are important, they are generally considered to be secondary to sediment characteristics in shaping the infaunal community.
