Expert Solution & Answer

Explanation of Solution

The mechanisms that might allow a species to maintain its characteristic distribution are as follows:

The physical and chemical characteristics of water masses, such as temperature, nutrients, and salinity limit the horizontal or geographic distribution of plankton.
Gyre systems do not mix with surrounding masses. However, it shows little mixing with surrounding masses. In these masses and other masses, planktons are uniformly distributed.
Biotic factors such as limitations of food and predation may influence the patchy pattern of distribution.
