Why was modern classification invented?
Traditional classification could not classify all living things.
Scientists realized related organisms do not share similar characteristics.
Scientists understood that species share a common ancestor.
Modern classification is faster and easier to use.

Modern classification was invented because Scientists understood that species share a common ancestor.

Explanation:

Classification refers to the method of categorization of  organisms in which the organism are categorized according to the similar characteristics and are further grouped into categories and can then be identified.

The traditional classification is usually based on the shared characteristic of an organism.whereas the Modern Classification is based on the  evolutionary relationship that exist among the organism

The modern classification system has derived its root from the system that was developed by Swedish botanist Carolus Linnaeus .The modern classification system also holds similarity with the  Linnaean classification system. which talks about the similarities in the physical traits of an organism.

Hence we can say that ,Modern classification was invented because Scientists understood that species share a common ancestor.

the answer is d.Modern classification is faster and easier to use.

Explanation:

your spelling is a little off : ]

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
