which of the following explains why aquatic plants can live in the benthic zone of shallow lakes?
they cannot tolerate saltwater
the bottom is always warm
sunlight reaches the bottom
they live on decaying organisms

Explanation:

Aquatic plants need sunlight for photosynthesis. In the benthic zone of shallow lakes, sunlight can reach the bottom, which is essential for their survival. The option "they cannot tolerate saltwater" is about salinity tolerance, not related to the benthic zone of shallow lakes. "The bottom is always warm" is not a general and key reason. "They live on decaying organisms" describes decomposers, not typical aquatic plants' main survival factor in the benthic zone of shallow lakes.

Answer:

sunlight reaches the bottom
