Why is the interaction a frogs digestive and circulatory system important for its survival?

Well.... The frog needs nutrients in order to survive. When the frog would eat its food, the food would go down through the digestive system, where obviously the food would break down. Then the circulatory system would take the broken down food and spread the nutrients that were taken from the food, all across the frogs body.

So the main answer is that a frogs digestive and circulatory system are important for its survival because the frog needs nutrient given to its body. The two systems work together to break down the food and spread the nutrients across the frogs body.
