Answer: option B) False
Explanation:
The body relies on SEVERAL sources for its energy or glucose supply.
Firstly, understand that Glucose could be supplied from the following:
Glycogenolysis (Glycogen break down induced by Glucagon)
Amino acids metabolism (once amine group is removed)
Fatty acid oxidation.
All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.
Therefore, the answer is False
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are:
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
I believe the answer is 3.
