The proportion of energy transferred from one trophic level to the next is known as trophic level transfer efficiency or ecological efficiency. The Ten Percent law states that 'net production at one trophic level is generally only 10% of the net production at the preceding trophic level'. In this example, the producer contains 6000 units of energy. 10% of this will be transferred to the primary consumer, i.e. 600 units. In turn, 10% of this energy will be transferred to the secondary consumer i.e. 60 units.
Answer:
A skeletal muscle fiber is surrounded by a plasma membrane called the sarcolemma, which contains sarcoplasm, the cytoplasm of muscle cells.
Explanation:
I believe the answer is the weight of each tomato.
This is because the weight of each tomato depends on the amount of fertilizer (the independent variable/the thing being changed) added to each plant.
Answer:
(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Explanation:
As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.
Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.
This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.
