How does energy move through your ecosystem? think about the producers (plants) and how energy moves from producers to other organisms?

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

it is either c or d and i know for sure it is not a or b
