The availability of oxygen and other electron acceptors is the most important determinant of the types of metabolisms in a habitat. Which of the following is NOT true about anaerobic environments?

A) They have slower rates of assimilation compared to aerobic habitats.
B) Their rates of dissimilation are slower compared to aerobic environments.
