Biologist classify all living things into overall groups called kingdom. the members of each kingdom are alike in their fundamental characteristics. The kingdom of life is divided into six different kingdoms.
ANIMALS: Animals are multicellular organisms that obtain energy by ingesting food. All animals are capable of moving at least some part of themselves and many can move from place to place.
PLANTS: Plants are multicellular organisms that grow by harnessing the energy in light. through a process called photosynthesis. They use this energy to build up organic matter from simple material creating most of the food animals rely on
FUNGI: Fungi are multicellular organisms that grow by collecting energy organic matter which they do not ingest but breakdown externally by making threads that spread throughout their food. many fungi are to little to be seen and some have large fruiting body.
PROTOCTISTS: They are single celled organisms that typically live in water or in permanently moist habitats. their cells are large and more complex than those of bacteria. Some protoctists behave like plants, They absorb sunlight to produce energy. Other called Protozoa are like animals, They survive through consuming food.
BACTERIA: Bacteria are the simplest independent living things. their cells are prokaryotic in nature that means they lack in membranous organelles. Bacteria survive on different sources of energy like sunlight, organic and inorganic matter.
ARCHAEA: Achaeans are single celled organisms. They use to be classified with bacteria but due to their difference in molecular organization. They are now believed to linked with ancient group of organisms that are intermediate between the bacteria and eukaryotes.
