Explanation:
Answer:
(First) 10,000--->1000--->100-->10 (fourth)
Explanation:
Each trophic levels gets reduced by factor of 10.
Thus if you start with 10,000 in first, then you end with 1000 in second, 100 in third and 10 in forth.
The correct answer is active hyperemia.
Active hyperemia represents the increase in organ blood flow (hyperemia) that is associated with the increased metabolic activity of that organ. In this case, the increase in blood flow accompanies muscle contraction during the exercise. Muscle contraction stimulates the production of vasoactive (vasodilative) substances that dilate the vessels and thus, bring more oxygen to the muscles.
Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. biomass is the total mass of organisms at a trophic level.
