Irecently had a biology exam and one of the questions was: at what trophic level does the leopard feed. with the attached picture. i thought it was pretty obvious that they wanted the trophic levels of the animals the leopard eats so i answered fourth and second level. teacher said it was wrong they wanted the troophic level the leopard is at . what do you think the question asks for since i lost marks for it and am confused

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.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
