-Polygenic inheritance
Explanation;
-Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect.
-Examples of polygenic inheritance in nature can be found in many places: in human height, skin color, and hair color; in animal size, longevity, or disease resistance; and in plants with grain color, length of maize, or flower size. All of these traits are influenced by multiple genes and considered polygenic.
Answer:
<h2>100 kcal</h2>
Explanation:
Energy transfers from autotrophs ( producers) to heterotrophs (consumers).
In this way approx 90% of the total energy is consumed by each trophic level, means only 10% energy is transferred from each tropic level.
So as given here, in primary trophic level ( producers), total energy is 10,000 kcal.
Now the 90% (9000 kcal) of this energy is consumed( like in the form of heat and respiration) in trophic level 1 and 10% (1000kcal )is transferred to the trophic level 2( first-order consumers).
And from this energy 90%(900kcal) is consumed in trophic level 2( first-order consumers) , so only 10% (100 kcal) is transferred to the trophic level 3 (second-order consumers).
