What is one major difference between how matter moves through an ecosystem and how energy moves through an ecosystem?

Matter is recycled: living things die and decay, for example. The nutrients living things need are obtained from plants or organisms that eat plants. The food chain thing. Energy flows on a one way street - the sun's energy is used by plants, then food chain again, and finally excess energy is radiated by the earth into space. There's no way to store and re use energy as there is for matter.

Net force required to accelerate the car is 6000 N

Explanation:

Force is calculated by the equation, F = Mass × AccelerationThis is based on Newton's Second Law of Motion which states that the force acting on an object is its mass times the acceleration of the object.

Here, mass = 3000 kg and acceleration = 2 m/s²

⇒ Force = Mass × Acceleration

              = 3000 × 2 = 6000 N

⇒ F = 6000 N

⇒ M = 3000 kg

⇒ a = 2 m/s²
