=Group 4 = = E c o s ys te ms = Aquarium Notes - the algae carry on photosynthesis to produce their own food,they are called producers.producers make the food that animals reed to live. since animals cannot produce their. own food, they must each other orangism to get energy. this is why animals,such as the moose and tiny water flue,are known as consumers.

The procedures of making an aquarium are:
1st: You have to wash the gravels so it won't be clouty. == 2nd:Put the gravels on the bottle you prepared. 3rd:put water on the bottle that the gravels are in. 4th:get the plants from your teacher and observe them. 5th:after observing,put the plants your teacher gave:duckweed,elodea,algae. 6th:put it near the sunlight for your water plants to grow

1) What is an ecosystem?
Ecosystem is living things in a particular area and parts that affect them. It it also a relationship of living things and their surroundings.

2)How are living and non-living things connected to one another?
It is a tropic level. An

example of and tropic level is : A seed gets it's energy from the sun. A butterfly gets some nectar from the plant. Then a bird eats the butterfly and rat eats the bird. Finally, the cat eats the mouse. When it dies and it's buried, the nutrients from the cats body scatter through the soil.

3) How does the use of its resources affect an ecosystem?
It is most made from humans.Cutting down trees and making it for houses, buldoising wet lands, damning rivers, using water from the river systems to water crops. That affects our EARTH'S ecosystem.

4) How are resources used by different groups?
The trees give us carbon dioxide so, if we destroy our forests, our oxygen will pollute and there won't be trees to make the air as fresh as before. Even we use trees to make some of the most important medicines!

5) How can our choices affect ecosystems?
Our choices of recycling paper can save a lot of trees. Don't kill the animals and plants to make or do something wrong. We can : 1.Manage 2.Protect 3.Conserve

6) Why do some people think it is important to protect ecosystems?
Some scientists and people think that because, it's known that, If you take out something from an ecosystem completely, you might upset the balance and the system might not work because of upsetting the balance.
