Which of the following describes a relationship of predator-prey?

A. A tick attaches itself to the inside leg of a deer.

B. A moray eel eats a fish swimming by.

C. Birds feed off the insects that are stirred up from the grasses as cattle move through.

D. Oxpecker birds eat parasitic ticks off the backs of zebras.

Option C) Birds feed off the insects that are stirred up from the grasses as cattle move through.

Explanation:

A predator is a living organism (usually of bigger in size) that feeds on whole of another organism (prey).

When cattle move through grasses, their hooves displaces insects which are sighted and fed on by flying birds.

Thus, the birds are predators while the insects are prey

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

i think the answer is c hope this
