Semmy [17]

Answer:

The correct answer is D) domain

Explanation:

The father of taxonomy is Linnaeus. Taxonomy helps in classify and naming organisms. The modern taxonomy has eight levels of classification. Domain, kingdom, phylum, class, order, family, genus, species.

Domain is the highest level of classification so it is the largest category that would include closely related species. When we go from domain towards species the number of similarities increase and number of organism decrease and vice versa is true when we move from species to domain. So the right answer is domain.

Which wavelength in photosynthesis which has the highest amount of energy?

Violet and blue have the high frequencies (thus energy) of visible light. Red will be the least energy but lowest energy. And remember, chlorophyll is green because it reflects green into our eyes. Green is therefore not absorbed, so not used for photosynthesis.
