Which of the following would cause a decrease in the number of species in an ecosystem? a decreasing the number of predators
b increasing the food supply
c increasing the produceſ population
d introducing a competing species

d) introducing a competing species.

Explanation:

Competition refers to a dynamic partnership in which various species or populations in the environment concurrently seek to utilize the same available resources. Organisms in an ecosystem compete for the same limited nutrients and in the process, one ultimately got an edge over the other. because resources are limited in nature, the population of one species decreases at the expense of the survival of the other.
