Species
Species
The kingdom level of classification contains the most diversity and number of organisms. It is the broadest level where organisms are grouped based on shared characteristics.
The highest level, called Domain, contains all of the other levels, and thus by default, contains the most organisms (all of them).
On an ecological pyramid or in a food chain, typically, the highest trophic levels have the least amount of energy from the sun available for the next highest level. In a typical food chain, this would be the tertiary consumer level.
Species
species
The highest level of classification, domain, has the least variety of organisms, encompassing only three major groups: Bacteria, Archaea, and Eukarya.
the one with the most organism is domain
kingdom
The class of animals that contains the least examples is the family, as it is the lowest level in the classification of animals.
Species
No, organisms in the same kingdom do not have to belong to the same domain. Kingdom is a broader classification level than domain. Organisms in the same kingdom share similar characteristics and traits, but they can belong to different domains, which are higher-level classifications.
