Acceleration is defined as the velocity of an object over a period of time.
Mathematically,
Acceleration, A = Velocity [V] /Time [T]
From the question given above, we are told that
T = 30 seconds
Initial velocity, V1 = 5
Final velocity, V2 = 2
Change in velocity, V = V1 - V2 = 5 - 2 =3
A = V / T = 3 / 30 = 0.1
Therefore A = 0.1 m/s^2.
Answer:
The amount of energy that's being transfered becomes smaller.
Explanation:
Say a grass hopper eats grass. It gets 1000 units of energy. It uses up energy. Next a bird eats it. It only gets 100 units of energy. Next a cat eats the bird. The cat only gets 10 units. If something eats the cat, then it gets 1 unit of energy.
The biggest reason for deforestation is for supplies to build homes.
A natural resource that is limited in supply
Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass. The next link in the chain is animals that eat herbivores - these are called secondary consumers -- an example is a snake that eat rabbits.
