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:
Ozone
Explanation:
In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen.
Answer:
Hello!
Primary consumers and producers are two examples of <u>trophic</u> levels, a way to classify living organisms based on their source of nutrients.
Hope this helps!
Answer:
All of the above
Explanation:
The definition of ecosystem is "a biological community of interacting organisms and their physical environment." and all four of the answers fit the bill.
This is because the equator is closest to the core and loses heat the farther away it gets. Heat enery is transferred by going through the ground warming the ocean since the core is twice as hot as the sun
