The number of primary consumers would increase because they would not get eaten.
<span>I believe the Answer is Population.</span>
Answer: D. at most 10
Explanation:
Using the energy pyramid, the ratio of grassland to primary consumer to secondary consumer is: 100:10:1 respectively.
Thus if the grassland supports 100 cattle (primary consumer), the numbers of humans (secondary consumer) the cattle can feed will be;
100/10 = 10.
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
