D Correct answer
Explanation

Littoral zone is the shallow coastal zone. Light is available upto bottom in this zone. Therefore, producers are found throughout from surface to bottom in this zone. Rooted vegetation occurs along shores. Consumers are also available throughout, i.e., from surface to the bottom in this zone.

  3. Water holding capacity of soil

  4. Light reaching the forest floor
