A. Loss of frogs is likely to increase grasshopper populations so all bird populations are also likely to increase.

B. Loss of frogs is likely to have little effect on bird populations because birds can easily switch food sources.

C. Loss of frogs is likely to have positive effects on some bird species and negative effects on others.

D. Loss of frogs is likely to negatively affect all bird species in the food web because a prey species would be lost
