Answer:
Pond
Explanation:
Ponds are inland water bodies that are usually smaller in surface area than a lake and nonflowing in contrast to rivers or streams. However, a pond is a shallow freshwater source that inhabits organisms' life (plants and animals alike).
Due to the shallow state of a pond, light penetrates to the bottom, hence, allowing the constant growth of plant life. Therefore, PONDS are freshwater sources that contains a permanent shallow body of water with plant life throughout.
No diagram shown, but it would be the fish/any other organisms near or in the shallow part/any part of a pond/lake.
