what will happen to a population of organisms that are in an environment with little to no oxygen?

Answer:
Hypoxia occurs when algae and other organisms die from lack of oxygen and available nutrients. Hypoxia events often follow algal blooms. The cyanobacteria, algae, and phytoplankton sink to the seafloor, and are decomposed by bacteria. This lack of oxygen creates dead zones in which most aquatic species cannot survive.
