Animals and most microorganisms are classified as chemoorganoheterotrophs. The prefixes "chemo," "organo," and "hetero" refer to how the organism meets its needs, respectively, for:

(A) electrons, carbon, and energy
(B) carbon, energy, and electrons
(C) electrons, energy, and carbon
(D) energy, electrons, and carbon
(E) carbon, electrons, and energy

Option A.

Electrons,carbon and energy.

Explanation:

Chemorganoheterotrophs are organisms that uses organic substrates to produce carbon needed for their growth and development. They derive their energy from oxidation and reduction of organic substances. The use the reduced carbon produced by autrotophs as as source of electrons, carbon and energy. Example is fungi that uses carbon as electron donor and source for carbon and energy.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
