About how much energy is transferred from a primary consumer to a secondary consumer?
90% of the original energy from the sun
10% of the original energy from the sun
10% of the primary consumer's energy
1% of the primary consumer's energy

The correct answer is 10% of the primary consumer's energy.

According to the law of 10 % energy transfer-

10 % of the energy is transferred from one trophic level to the subsequent trophic level in a food chain. The remaining energy is utilized in the metabolic processes of the organism or released as heat in the atmosphere.

Primary consumer ( like herbivore) and secondary consumer ( like carnivore) are the trophic levels of the food chain. Primary consumers get energy by consuming producers like plants whereas secondary consumers obtain energy by eating primary consumers.

Thus, 10 % of the energy from the primary consumer is transferred to the secondary consumer.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
