Cranefly Larvae Lab Report

The species that is the direct variable in this experiment is the Cranefly larvae. This species does not stay as a larvae its entire life. The Cranefly larvae is one of the many species that goes through a cycle of different stages in its life. Since the larvae go through 4 different stages it is called complete metamorphosis. The first stage the species has being in an egg. After the mother Craneflies eggs are fertilized, they then release their eggs over temperate waters. As the eggs are released they fall into the water and will descend into the stream bed. After they complete this stage of their life then the Craneflies hatch out of their eggs as larvae. This is the stage in which the species are in for the experiment. During this
It is not just Cranefly larvaes that would be affected by this but also thousands of other types of species. Wetlands are one of the many ecosystems that allow different types of species to survive in it like. Examples of these types of species are birds, plants, amphibians, insects, fish, microbes, and mammals. The wetlands also provide these species with food and breeding grounds Wetlands don't just support the species that live in them they also help the land around them. One of the ways wetlands help is water can get filtered of most of its harmful substances from humans before going into the main water sources. They are filtered by the plants and bacteria that can absorb the harmful substances and break them down to not as bad harmful substances. Wetlands also protect the land because they help solve some of the erosion problems that harms the shorelines, lakes and streams. The wetlands do this by absorbing some of the extra water from flooding. If the wetland were all destroyed then there would be thousands of species with no adequate home for them, more harmful substances in the water like fertilizer, and there would be extreme amount of erosion along the water
