Answer 1

Decline in the number of frogs would affect other species as in a food chain each species are dependent on each other for food.If there is a decline in frogs,then the previous topic level of food chain consisting of insects would increase in number as they will be no frogs to eat them...the relationship of frogs to algae is similar....if there is decline in no. of frogs...then there will be an increase in algae...hope it helps thankyou
