An ecosystem is a community of interacting living and non-living elements that are dependent on balance. There are seven main types of ecosystems: forests, meadows, ponds, lakes, wetlands, estuaries, and coral reefs. An ecosystem contains abiotic (non-living) elements like air, water, soil, and sunlight that make life possible, as well as biotic (living) elements including plants, animals, and decomposers. Plants are primary producers that provide food, animals are consumers that eat plants or other animals, and decomposers break down dead organisms and cycle nutrients.

- 7. PLANT LIFE Also called primary producers Provide food for other living elements of the ecosystem Live off non-living elements Make own food from sunlight
- 8. ANIMAL LIFE Also called consumers Eat plants and/or other animals Three different categories Herbivors- ex. rabbits, sheep Carnivores- ex. lions, sharks Omnivores- ex. foxes, raccoons
- 9. DECOMPOSERS Also called detritivores Eat via decomposition Turn dead plants and animals into nutrients for living plants Brings the ecosystem full circle

Editor's Notes
- #3: Ecosystems depend on balance because without balance the ecosystem would die. It wouldnt be able to keep up and sustain all of the organisms living in it. If there are too many consumers and not enough producers the animals will not have enough food and will die off.
- #5: Give examples of things you might find in each of the seven ecosystems. Forests might have bears and/or deer, meadows have a lot of grass and flowers, ponds and lakes have fresh water fish, but coral reefs have saltwater fish, etc. Top row: forest, pond Bottom row: lake, coral reef
- #6: This is like an introduction slide to the rest of the presentation giving the audience a quick look at what will shortly be talked about more in depth.
- #7: Order of pictures: sunlight, rock, water Give examples of how some of these make life possible: air provides oxygen for us to breath, sunlight helps plants grow which in turn feeds animals, soil gives plants nutrients, water helps plants grow and animals live, etc.
- #8: Plants use sunlight to make their own food, and they get nutrients from the soil around them. They are then eaten by animals, giving them nutrients
- #9: Animals are called consumers because the consume the producers. They eat plants and/or other animals. Herbivores eat strictly plants, Carnivores eat strictly other animals, Omnivores eat both plants and other animals.
- #10: They eat dead plants and animal, when they eat they complete a process called decomposition, which gives them food and in turn returns nutrients to the soil which feeds plants and so on completing the cycle.
- #11: Each answer comes up separately click to reveal the answers one by one the answers in parenthesis also come up separately to give a more specific answer.
