Question

shallow areas of water that can be penetrated by sunlight are part of what zone? * 1 point
benthic zone
photic zone
littoral zone
pelagic zone
aphotic zone

diverse aquatic habitats where freshwater and saltwater mix are called what? * 1 point
estuaries
marshes
fens
wetlands
bogs
lagoons

Explanation:

For the first question, the photic zone is the part of a body of water that receives sunlight, allowing photosynthesis to occur. The benthic zone is the ecological region at the lowest level of a body of water. The littoral zone is the area near the shore. The pelagic zone is the open water column away from the bottom and shore. The aphotic zone is the part of a body of water where there is little or no sunlight.
For the second question, estuaries are coastal areas where freshwater from rivers and streams mixes with saltwater from the ocean. Marshes are wetland areas dominated by herbaceous plants. Fens are a type of peat - forming wetland. Wetlands are areas where water covers the soil. Bogs are a type of wetland that accumulates peat. Lagoons are shallow bodies of water separated from a larger body of water by a barrier.

Answer:

1. Photic zone
2. Estuaries
