Tick sucking blood : parasite-host : : a) deer eating shrubbery : consumer-carnivore b) shrimp cleaning fish teeth : parasite-herbivore c) orchid on a tree : producer-consumer d) lion eating a zebra : predator-prey

If this is asking which is correct it would be d. :)

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.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
