2. ecosystem Ecosystem is made out of a communityof organism and the abiotic environment. Ecosystem could exmine how organisms interact. These nutrient affect the growth of the cordgrass and algae.

3. How ecosystem work An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together. If there isn't enough light or water or if the soil doesn't have the right nutrients, the plants will die. If the plants die, animals that depend on them will die. If the animals that depend on the plants die, any animals that depends on those animals will die. Ecosystems in nature work the same way. All the parts work together to make a balanced system!

4. The ecosystem helps the world in many ways, with preventing over population in the animal world, and helps new things grow like plants. Plants and animals need stable environments, so if you go and ruin it; it could ruin their homes. It does not have any negetive effect on the world, besides maybe some animal species going down because of the larger predators. The ecosystem gives us food and water. To help the environment we could recycle more so the animals can't die and the plants can grow to be beautiful. We could also stop driving so many cars and stop polluting the air. World wide we can stop pollution, stop dumping things into the water or on sides of roads. All of these things can help the environment and save a bunch of animals and plants in those environments.
