You are observing species population in a community in which owls and snakes both consume only mice. If the population of snakes decreases significantly, which of the
following would you expect to observe first?

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
