What are the names of the species used in this experiment? Which of these species was the most tolerant of increased acidity in the aquarium? Which species was the least tolerant?
The names of the species used in the experiment were clam, dragonfly, and side swimmer. The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems.
Acid precipitation affects the ecosystem, for example, lowering ph in water when it falls into the lake which kills some aquatic organisms.
What is an indicator species? How are indicator species used to assess pollution levels in the environment?
Indicator species are particular aquatic invertebrates that alert us to pollution problems in an environment. Indicator species are used to assess pollution because they change rapidly in response to changes in ecological variables, such as food availability, water temperature, amount of dissolved oxygen in the water, pH levels, and other factors.
Suppose you are an ecologist studying the effects of acid precipitation on plant life. Describe an experiment you would perform in order to determine which plant species would be a useful indicator species for acid rain pollution.
An experiment that I would use to perform in order to determine which plant species would be a useful indicator species for acid rain pollution would be similar to the experiment we just performed on aquatic invertebrates. I would gather numerous plant species and test how they react when ph levels lowered, keeping record of reactions, and formulating my conclusion from that information.
How do the data represented on the Population Bar Graph compare to the data represented in the line graph titled Populations of Aquatic Invertebrates at Various pH Levels?
The two graphs are clear presentations of how different ph affect the populations of the species. In the line graph titled Populations of Aquatic Invertebrates at Various pH Levels,

    To do this, we pulled rocks out of the creek and put them on land. There are three stages of groups, the first group means that the creek is not polluted. The second group means there is some pollution. The third group means that the creek is extremely polluted. For group 1 our group found 59 organisms. For group two, in our study, we found 15 and they were all scoud. In the group 3 we found 27 creatures. This is what we did in station 3 for the creek study field trip.…

    In this research and experiment we were testing whether or not we can maintain a healthy eco-system based off creating one from scratch. We initially went into this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data, we maintained a healthy terrestrial level and a good PH level which came as a surprise due to the death of our aquatic fauna and the levels of turbidity. In summary the project was a challenge in a sense of trying to keep our fish alive and whether or not the fish was retrieving enough nutrients and food. Recreating nature was not the easiest task.…

    a. Round 1 = white bead representing lichens. Our laboratory reading for the experiment stated that lichens are instrumental in the development and needs for all species. The text stated, “Lichens play a part in the creation of soils from which plants can obtain nutrients. Like all living organisms, lichens need nutrients and energy to grow. Nutrients may be obtained from the air including dust, water, and from the substrate organisms grows on obtaining energy through photosynthesis, which is the role of the algal partner. They may also be incidentally fertilized hybrid and insect dung” (Bottcher & Rex, 2012, p. 43). With the information obtained from the reading, without lichens, bees, trees, flowers, and humans will all have negative repercussions.…

    Acid rain is usually a result of human air pollution such as emissions of sulfur and nitrogen compounds. These compounds react with those in the atmosphere causing acids to be produced and in turn causing precipitation to be acidic in nature. The negative impact of acid rain is evident in ecosystems. Acid rain changes the PH levels of rivers and lakes. Animals such as fish are very susceptible to changes in PH and therefore are unable to survive if the change is too drastic. Plankton and invertebrates are put even more at risk. Acid rain in water environments can also affect plant life. On land, acid rain damages forests in high altitudes and also lowers the fertility of soil as important nutrients and minerals are removed from it. These impacts on different aspects of the environment have a trickling down effect that negatively influence entire…
