Arecent study has shown an increase in the number of predators in an ecosystem. which of the following is a possible cause for the growth?
a. a decrease in the population of prey it feeds on.
b. an increase in the population of prey it feeds on
c. a decrease in the biodiversity of the ecosystem
d. an increase in the number of predators that feed on it

b. An increase in the population of prey it feeds on.

Explanation:

A predator is a kind of organism which kills the other organisms so as to obtain them as food. The organism which is killed is called as prey. If the population of predators in an ecosystem increases the result for this increase is the increase in population of prey which the predator population can use as food to survive, reproduce and grow in number.  

who knows

explanation:

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
