How does photosynthesis and cellular respiration move carbon, nitrogen, and water through the different Earth systems (biosphere, atmosphere, hydrosphere, and geosphere)?

well the plants live and die from life to death they get there nutrients from water from rain. and oxygen from the air and nitrogen from the ground. the plant grows and dies. when it dies it decompose and puts nitrogen back into the soil along with the seeds that where produced in it's life time.

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.
