circadian rhythms → Pollen-producing structure at the top of the stamen, the male reproductive organ of flowers.
aphotic zone → Literally, zone without light. The aphotic zone is part of the marine pelagic zone and begins 600 feet below the surface of the ocean. Only chemosynthetic organisms, scavengers, and predators are able to survive in this habitat.
