Answer:
But the mixing of freshwater streams and rivers with salty ocean tides in a partly enclosed body of water—natural scientists call it an Estuary—fuels some of the most productive ecosystems on Earth, and also some of the most vulnerable.
continental shelf
The continental shelf is that shallow part of the ocean floor that begins at the shoreline and gently slopes underwater to an average depth of about 430 feet. It is covered with thick layers of sediment (sand, mud, and rocks)
What kinds of plants and animals live in estuary and intertidal zones?
Some of the organisms in this area are abalone, anemones, brown seaweed, chitons, crabs, green algae, hydroids, isopods, limpets, mussels, nudibranchs, sculpin, sea cucumber, sea lettuce, sea palms, sea stars, sea urchins, shrimp, snails, sponges, surf grass, tube worms, and whelks.
Why should we not throw waste into the water?
If garbage is dumped into the ocean, the oxygen in the water could be depleted. This results in poor health for marine life due to lack of oxygen. Animals such as seals, dolphins, penguins, sharks, whales, and herring could all die. Bottles and other plastics including bags can suffocate or choke sea creatures.
I hope it helps...,, base on my research too...,,☺️☺️☺️
