Question

3. Refer to the equation below.



Why are the two terms labeled as 1 and 2 connected by a minus sign? Because an increase in the population of species A has a negative effect on the growth of species B Because an increase in the population of species A has a positive effect on the growth of species B Because an increase in the population of species B has a negative effect on the growth of species A Because an increase in the population of species B has a positive effect on the growth of species A B Y2

Explanation / Answer

Ans 3 C . Because increase in population B has a negative effect on growth of population of species A

The formula shows growth in population of species A over a time interval on left hand side, which is then equalised with the difference in growth of species A and B. This indicates that species B has a negative effect on species A growth that's why minus sign is used. Had it been a positive effect, plus sign would have used.
