Eating Two-Variable Linear and Exponential Equations: Tutorial 43
Activity
Suppose a scientist is watching a video that models the growth of bacteria. He is taking screen shots of the video after
every second of "video time," with each second of video time correlating to 20 minutes of "real time." In the video, each
bacteria cell splits into two cells with each passing second, as seen in the images from the video. In these screenshots, t is
the video time in seconds.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
