The correct answer is D. ponds and lakes.
Explanation:
1. Ponds and lakes are examples of freshwater biomes that contain a limnetic zone surrounded by a littoral zone.
2. The limnetic zone is the open, well-lit surface area of a body of water where sunlight penetrates, supporting photosynthesis and primary production.
3. The littoral zone is the shallow area along the shore of a body of water where aquatic plants grow and where most of the biodiversity is concentrated.
4. In ponds and lakes, the limnetic zone is the open water area, while the littoral zone is the shallow area near the shore where plants like water lilies and cattails can be found.
5. This distinction between the limnetic and littoral zones is characteristic of ponds and lakes, making them the correct choice for the given question.
