Pond Ecosystem
==Hi my name is “ The Intriguing 2.5”. I’m in the sixth grade in Amigos School located in Cambridge, Ma. Everybody in this grade is doing an ecosystem wiki. We do this for people all over the world would know about an ecosystem. Mine is the pond ecosystem. We went to a pond named Black’s Nook’s Pond in Cambridge. The pond was full of biotic life.== == Our field trip was to Black Nooks Pond in Cambridge. We left the school about at 9:10. We got there by bus. We got there about at 9:40.There was a lot of water and dirt. We had to measure the ph, temp, turbidity, and the dissolved oxygen of the water. Then we checked the temp of the air. We used a thermometer to check the temp. The temp of the air was 72º F and of the water it was 70º F. We measured the ph with a strip and based on its color that’s the amount of acid is the water. The ph was 7. It was perfect. For the turbidity we had a cup and it had a circle on the bottom. We put some water in it and observed the visibility of the water. It was 20 JTU. For the dissolved oxygen we put a pill in the water and measured the oxygen. It was 024 PPM. == == The ecosystem I’m doing is the pond ecosystem. For the producers I saw lilly pads, poison ivy, and smartweed. Producers are plants or animals that make their food my absorbing sunlight and making it into its food. 1st level consumers are herbivores, they eat plants (vegetarian). For that I got chipmunks, tadpoles, and zooplankton. 2nd level consumers are omnivores. They eat both meat and plants. Frogs, water scorpion, zooplankton. 3rd level consumers are the predators. Hawk, great blue heron and zooplankton. The decomposers decompose dead matter. Lichen, centipede, and mushrooms. The energy pyramid works perfectly. The sun starts with all the energy than it goes to the producers than the 1st level consumers eats the producers than the energy goes to the consumer. Than the 2nd level consumer eats the consumer than the energy goes to it. Than the energy goes to the 3rd level consumer because it eats the 2nd level consumer. == == My ecosystem is the pond ecosystem. I learned that zooplankton go in all 3 consumers since they eat other. We looked a plants and animals. We found consumers and producers. We caught plankton. With out producers there wouldn’t be a ecosystem. ==
