An energy pyramid is helpful in understanding the relationship between food and energy, because the most energy (generally grass, or plants) is at the bottom, and meat eating predators are at the tippy top (less energy). Producers, primary consumers, secondary consumers and tertiary consumers are all on the energy pyramid. I hope this was helpful:)

"Net force" simply means the sum of all forces. The "unless acted upon by a net force" version is more correct. For example, as you stand or sit still, the earth pushes you up with a force equal and opposite to the force with which gravity pulls you down. The net force, or total force, is zero, so you do not move.
