Answer:
Because they are farther away
Explanation:
Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.
Case 1: Corn to human:
Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.
Case 2: Corn to cow to human:
Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.
It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
Answer:
It decreases
Explanation:
The sun provides energy for plants to grow and then animals eat the plants and humans eat animals throughout the transfer of energy through digestion energy is lost via digestion and excretion.
<u>Explanation:</u>
now a days we dont need gooosbumps or the scientifc name cutis anserine.
it was used by our ancestors when we got afraid or for the cold an example of this is if a predator is attacking us the hair on our skins would point straight and we'd look bigger and hopefully it would scare them away, we can still see this in animals... but in present day its completly useless
Answer:
a mass above sea level is supported below sea level, and there is thus a certain depth at which the total weight per unit area is equal all around the Earth
