The results from this experiment showed that the control group increased their phosphate levels more so than the experimental groups, which contained the red wriggler earthworms. This could have been due to high amounts of Ca²⁺ in the water…

    land decreases as the marsh reaches towards the marsh front, and figurative – that data taken from sample sites at the marsh such as pH, amount of organic matter deposited within the soil, and amounts of specific sediments deposited within the soil has a linear pattern as the marsh extends to the shore. This report will examine elevation, soil pH, water salinity, and soil texture data from unbiased sample sites in hopes of finding a relationship to support the hypothesis of this…
