Marine ecosystem

Marine ecosystems are among the largest of Earth's aquatic ecosystems. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content. Marine waters cover two-thirds of the surface of the Earth. Such places are considered ecosystems because the plant life supports the animal life and vice-versa. See food chains.

Marine ecosystems are very important for the overall health of both marine and terrestrial environments. According to the World Resource Center, coastal habitats alone account for approximately 1/3 of all marine biological productivity, and estuarine ecosystems (i.e., salt marshes, seagrasses, mangrove forests) are among the most productive regions on the planet. In addition, other marine ecosystems such as coral reefs, provide food and shelter to the highest levels of marine diversity in the world.

Question:im doing a science fair project on pond life. does anyone have any links about: 1.) How Ponds Form 2.) What wildlife are found in ponds 3.) Food Chains in Ponds 4.) Eco-System of a Pond 5.) is there a cycle of a pond?

Answers:I took a class (only a week long) about pond life over the summer. Here's what I can remember. 1. I don't remember how they are formed. 2. You can get anything from plants to tiny dinoflagellates (sp?) to fish to amphibians. 3. You get the typical food chain. Some of the tiny things can photosynthesize. Others filter out food particles in the water. Small fish eat these things. Bigger fish eat smaller fish. 4. Every pond has their own ecosystem, with different levels as you go deeper into the water. 5. I remember that ponds do eventually 'die'. Not quite sure on that one.

Question:

Answers:how will u set a pond on fire, well lets assume that for some reason u have gasoline on the surface of the pond, first the fire will kill all plants like algae etc and animals floating on the surface, if that is done u have a reduction in the population of such organisms aand as a result any other organism that feeds on those burnt out surface plants and animals will suffer and their population will reduce too or they might die off, so the chain continues and the ecosystem is now affected. ANother scenerio is that the fire might increase the temp of the pond and affect the dissolved oxygen or CO2 in the water this will also affect the well being of organisms in the pond, in extreme cases their might be no living organism left in the pond after a prolonged fire
