We did at beginning of the year it is fun at first i was in a group with Yaniv. In the middle I changed now i'm in a group with Josh and Kaden. We each have a thing every group have ether fertilizer or salt water or acid rain we have salt water. It is fun some times.
I have learned a lot about ecosystem. We have learned if one animal dies all animals will die because one animal eats another animal and if that animal dies all animals will die.They help the world like if we did not have a ecosystem the world would be mest up.
An ecosystem is in the woods or under the water where fish live. Learning about ecosystem's helped me because now I know if a whole species of fish die's then whatever eat's that species will die and so on. An ecocolumn changes because people put things in the water and the woods everyday and they die.
What is your favorite part of an ecosystem?
