Energy pyramids show the energy available to different trophic levels in a food web. The greatest amount of energy is available to the lower levels and thus, they can support the largest number of organisms. Using the model, what can you infer about the energy available to different trophic levels? Choose ALL that apply.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
