Which sequence shows the correct order of living things in a food chain?
kkurt [141]

The correct answer is option (A) leaves > deer > wolf.

A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.

In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.

What is the role of your kidneys in compensating for low levels of oxygen
TEA [102]

Explanation:

When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood.   The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.
