Which of the following correctly describes the energy relationship between first level consumers and second level consumers in this ecosystem? a. second level consumers have one-tenth as much energy available as first level consumers do. b. first level consumers have one-hundredth as much energy available as second level consumers do. c. second level consumers have one-hundredth as much energy available as first level consumers do. d. first level consumers have one-tenth as much energy available as second level consumers do.

well idk but i can explain it- so the first (plants) have the most, then it goes less and less. like a plant being eatin by bugs, then bugs being eaten by a monkey, then a lion eating the monkey. the lion gets the less and the [lants have the most.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
