b. A large rock falls from a cliff and breaks as it hits other rocks
When a skeletal muscle fiber is at rest, its ATP demands are met by ADP and creatine phosphate. In a resting muscle, excess ATP transfers its energy to creatine, producing ADP and creatine phosphate. This acts an energy reserve that can be used to quickly create more ATP. When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine.
A) ATP is the correct answer
Answer:
Because there are losses in energy between levels, the population between levels also diminishes. With less energy, there are less creatures that can be supported by it, so the level with the least amount of creatures would be the tertiary consumers, while the level with the most organisms would the producers.
