In a grassland ecosystem, if the population of grasshoppers (primary consumers) significantly decreases due to disease, what is the most likely immediate effect on the population of grasses (producers)?

✓ Correct Answer: Option B

Grasshoppers are primary consumers that eat grasses. If their population decreases, there will be fewer organisms consuming the grasses. This reduction in predation pressure will most likely lead to an increase in the grass population.
