The oxygen revolution changed Earth's environment dramatically. Which of the following took advantage of the presence of free oxygen in the oceans and atmosphere?
- (A) the evolution of
cellular respiration , which used oxygen to help harvest energy from organic molecules - (B) the persistence of some animal groups in anaerobic habitats
- (C) the evolution of photosynthetic pigments that protected early algae from the corrosive effects of oxygen
- (D) the evolution of chloroplasts after early protists incorpo-rated photosynthetic cyanobacteria
