viruses and pirons -- it should be noted that these 'organisms' are in the grey area between living and non-living things.
The highest level, called Domain, contains all of the other levels, and thus by default, contains the most organisms (all of them).
Species
the answer is species done and done
A group of similar organisms that can produce fertile offspring are species.
birds willinbreed with each other but so did dinosaurs back in the day on a small island in the tropics about 30 million years ago
INSECTS
Kingdom Animalia is the taxonomic classification group that contains the greatest or widest variety of organisms.
The highest level, called Domain, contains all of the other levels, and thus by default, contains the most organisms (all of them).
Plantae, Protista. I'm not so sure about Fungi.
The smallest taxonomic group that contains organisms of different species is the genus. An example of this would be the genus Canis, which includes multiple species such as Canis lupus (wolf), Canis familiaris (dog), and Canis latrans (coyote).
The largest division that a group of organisms can belong to is called a domain. There are three domains in the classification system: Bacteria, Archaea, and Eukarya. Each domain contains multiple kingdoms, which further classify organisms into smaller groups based on shared characteristics.
Species
Fungi generally reproduce using fruiting bodies.
The modern group designated as the animal kingdom typically contains multicellular organisms that pursue and ingest other organisms. They usually cannot make their own food.
Animalia contains only multicellular organisms.
the answer is species done and done
A group of organisms and their environment is a biome.
