Detailed explanation-1: -The littoral zone is shallow and gets a lot of nutrients from runoff and non-point source pollution. Therefore, it typically has an abundance of aquatic plant and algae growth. Some other common inhabitants of the littoral zone are cattails, reeds, crawfish, snails, insects, zooplankton, and small fish.

Detailed explanation-2: -Lakes. As with oceans, the benthic zone is the floor of the lake, composed of accumulated sunken organic matter. The littoral zone is the zone bordering the shore; light penetrates easily and aquatic plants thrive.

Detailed explanation-3: -Most noteworthy, the aquatic ecosystem includes freshwater habitats such as lakes, ponds, rivers, oceans and streams, wetlands, swamp, etc. Whereas marine habitats include oceans, intertidal zone, reefs, seabed and so on.

Detailed explanation-4: -Marine ecosystems are aquatic environments with high levels of dissolved salt. These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics.

Detailed explanation-5: -Swamps occur on flat, poorly drained land, often near streams and are dominated by woody shrubs or water loving trees. Freshwater swamps are the ideal habitat for amphibians because of the continuous moisture.
