When the energy flow through an ecosystem is measured at each trophic level, of the available energy passes from one level to the next. 1% to 2% 5% to 20% 25% to 35% 36% to 45% 46% to 55%?

Energy flow can be defined as the amount of energy that moves through a food chain and it flows through ecosystem in one direction. Thus, the largest source of energy for an ecosystem is the sun and the energy that enters the ecosystem is usually measured in calories or joules.

yes you are doing it right great gob

explanation:

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.
