Answer: This can be useful site to study the diversity of organisms.

Explanation:

The founder effect is the known phenomena proposed by Ernst Meyer. It occurs when a small number of organisms leave the larger population. The genetic variation will be lost when a new population is established by the small population. Due to lack of genetic variation the new population becomes phenotypically and genotypically different from the parent population. This process lead to speciation.

The islands are the regions where few organisms can be found, those have migrated from the native land. Thus the study of diversity of these organisms will become simple.

Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units.

STALIN [3.7K]

The maximum amount of energy that we should expect to be recycled from fox trophic level back to the grass trophic level is 0 units.

A food chain describes who eats whom in the wild. Every living thing – from unicellular algae to giant blue whales – needs food to survive. Every food chain is a possible pathway that energy and nutrients can travel through an ecosystem. The primary productivity of the grass is 200 units. There is a 10 fold decrease in the amount of energy units as we move upwards in production chain. So from grass to rabbits we lose energy. The foxes will only really have two units once it's decreased by 10 fold again. The grass does not get any energy from the decaying bodies of foxes, they get the minerals that they need to grow. And so the correct answer to this question is 0 units because when the energy gets recycled from fox trophic level back to the grass trophic level it will be totally reduced.

Note: The question seems to be incomplete. So the complete question is "Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units. What is the maximum amount of energy that we should expect to be recycled from the fox trophic level back to the grass trophic level? Answer choices: A) 0 units B) 0.2 units C) 2 units D) 20 units"

blsea [12.9K]

Answer:

Person starts to exercise.

Skeletal muscle oxygen demand increase

Skeletal muscle metabolism increases

.Blood delivery to the skeletal muscle increases is order to provide more oxygen

Oxygen sensors cause local blood cell vessels to dilate

This steps briefly describe the physiology of exercise.

At the onset of exercise, skeletal muscles cells were sustained with available oxygen from the Myoglobin. Myoglobin is oxygen binding and storage protein found in cardiac and skeletal muscles cells. it has high storing capacity for oxygen.

However as the exercise becomes intense ATPs supply drops, oxygen demand increases,cellular metabolisms demand also increase to supply glucose and ATP to the cells.

The liver mediates Gluconeogenesis. Fatty acid is broken down to glucose for cellular respiration with' ketone bodies build up..Exercise also stimulates the breakdown of muscle glycogen to glucose, Therefore, cellular respiration takes place to break down the glucose to C02, H20 and energy with rise in temperature.

However, oxygen concentration is low, therefore muscles cells undergo anaerobic respiration with lactic acid pathway. Lactic acid build up in muscles cells.The muscles cells under go oxygen debt to break down lactic acid to glucose in muscle.

Therefore to adjust the mechanism oxygen homeostatic sensors increases hyperventilation to increase oxygen intake through the lungs, and vasodilation. so that maximum volume of blood containing oxygen is transported to muscles cells; to sustain the intense activity
