If we are talking cellular respiration, most energy would be found being used in either the Krebs Cycle or for ATP.
The glucose harvested and created by plants is used in cellular respiration to create carbon dioxide, though the energy that the glucose offers is then utilized to perform the Krebs Cycle and helps ATP function at it’s top rate.
The option that u have selected is perfectly right.
Sea floor spreading occurs at divergent plate boundaries where the seafloor is being pulled apart by convection currents in the mantle. As the plate pull apart magma up wells and new crust is being formed. This process on the sea floor creates a habitat for exotic sea creatures such as tube worms. The food chain in this region of the planet starts with bacteria that metabolizes sulfur coming from hydro-thermal vents along the spreading ridge. <span />
