Why are marshes more productive than bogs? a. marshes have stagnant water. b. marshes get more sunlight. c. marshes are larger in size. d. marshes have more water flow.

THIS IS THE BEST ANSWER 👇

Option D, marshes have more water flow.

Explanation:

Nutrient-enriched marshes support a wide range of reeds, grasses and woodlands and bogs are used only as mosses, fungi and shrubs.

Hence, option D is correct
