The taxon that consists of one or more genera (plural form of genus) is the family.

Explanation:

According to the modern taxonomic classification system, there are eight major levels of division – Domain, Kingdom, Phyllum, Class, Order, Family, Genus, and Species.

Family is the taxonomic order which comes next to the Order and before Genus and consists of one or more genus or genera but sharing a common attributes. The ancestral origin of the family members remains the same.  

The kinds of families depend upon the Kingdoms and Orders in the taxonomy. Carl Linnaeus termed family as familia in his classification and divided the major plant groups or families as trees, palms, ferns etc.  

Among the family of carnivores in animals, there are many genera like Canidae, Felidae Ursidae etc.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
