Blababa [14]

The correct option is C.

The pyramid of numbers and the pyramid of biomass can be inverted but the pyramid of energy can not be treated in the same way. The pyramid of energy is a graphical representation of the flow of energy in the ecosystem. The ultimate source of energy in the ecosystem is the sun. The plants, which are called the producers use the energy of the sun to produce their own foods.

How did scientific names impact classification
Zanzabum
Actually, the names don't affect the classification at all - it does not matter how something is called, as it does not change its characteristics. 

The classification of organism is based on their evolution and characteristics and it's a scientific consensus based on the data. Names don't impact it at all. 

However, to increase understanding in science, scientist made the names after the place in the classification - so the scientific classification determines the names (but not the other way round). 

Most offten you can tell how an animal is classified from the name, but only because it was named after this classification.
