How does the Monera, Protista, and Animalia kingdoms obtain nutrition?
There is no single answer for the Monera and Protista. Monera are the prokaryotic organisms, like bacteria. Some bacteria are photosynthetic; some are chemosynthetic, but not all. Protista (the members are no longer considered a group) are eukaryotic, mostly unicellular, aquatic organisms. Unfortunately, many of them have characteristics of BOTH plants (they have chloroplasts and can photosynthesize) and animals. Others are heterotrophic. All animals are heterotrophic – they eat other organisms.
