The largest population would be the producers. In an energy pyramid, the producers have the largest biomass. The smallest population would be the top predators, since there isn’t enough energy to sustain this level in the energy pyramid.
Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.
Explanation:
Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.
Zero acceleration is implied on the bikes and the net force is BALANCED.
When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.
I believe it is A. Primary succession starts with plants and rocks.
