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.

Answer:
I'd need the data from the population sizes of the algae, walleye pollock, orca, ocean sunfish and sea turtles. And I'd also need water temperature data, levels of dissolved oxygen.
Explanation:
The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in
zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a
decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.
Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.
In human blood, there is a compound inside the RBCs called haemoglobin which ensures that the muscle will receive enough oxygen during exercise.
<h3><u>Explanation:</u></h3>
In human blood, the red blood corpuscles contain the haemoglobin. Haemoglobin is a iron chelated compound containing porphyrin ring and a globin tail which can establish co-ordinate covalent bond with both oxygen and carbon dioxide. The bonding element depends on the concentration of these two gases. In lungs, where the oxygen concentration is more than carbon dioxide, the haemoglobin bonds with oxygen and brings it to the tissues where carbon dioxide concentration is more. This makes the haemoglobin to release oxygen and bond with carbon dioxide which is brought back to lungs. This is the process by which each and every tissue including the muscles recieve oxygen.
In muscles there is Myoglobin which is another iron-porphyrin compound which has several times more affinity for oxygen than haemoglobin. This helps to extract more oxygen from haemoglobin in muscles.
