What is the primary function of decomposers in an ecosystem? a. decomposers are parasites; they attach themselves to host organisms and absorb nutrients from the host until the host organism dies. b. decomposers break down matter from dead organisms into simpler substances that can be recycled in ecosystems. c. decomposers absorb energy from the sun and produce food for themselves as well as other organisms. d. decomposers combine elements, such as carbon, nitrogen, and oxygen, into complex molecules that can be used as food sources for organisms.

Its B. Decomposers break down matter from dead organisms into simpler substances that can be recycled in ecosystems. I just had this questions and its not A, C or D

Ibelieve the correct answer would be c.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
