How the plants and animals work together?We will tell you about how the plants and animals survive together at site 5. First the trees help the beavers by giving them wood for the dam.The beavers use the wood for there dams they use the dams for homes. They use their homes to hide from predators. The dam helps the stream by slowing down the water so it makes the huge pool .Some animals use the pool for a home. Next the brush and trees help animals hide. If we didn’t have the brush and trees animals wouldn’t have a place to hide. If the animals didn’t have a place to hide they would all get eaten. If they all got eaten we wouldn’t have any animals at the creek. Also the macro invertebrates help tell if the creek is clean. If the water wasn’t clean our animals that live in the water would either die or not be able to live there if we didn’t have animals living there their would be no point.
This years water quality is good because our temperature was 48 our pH was7.5 our DO was 35%. We would like to see more Dissolved oxygen though. In conclusion now you know how the plants and animals survive together.
