What are the three types of ecological pyramids? Explain how each type of pyramid models energy and matter in ecosystems.

 The three types of ecological pyramids include the pyramid of number, which shows the number of individual organisms that exist at different trophic levels; the pyramid of biomass, which tell us the amount of living tissue or the total mass of organisms within each trophic level; and the pyramid of energy, which indicates the amount of energy at each trophic level and the actual role of each organisms in the process of energy transfer.

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.

within 30 of the equator hope this
