1: 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?
Dragonfly nymph, clam, crayfish, the dragonfly nymph is more tolerant to the increase of pH The crayfish was the least tolerant
2: Describe how acid precipitation affects ecosystems.
It makes the population of some species decline rapidly
3: What is an indicator species? How are indicator species used to assess pollution levels in the environment?
It is a species that indicates if the population size of an ecosystem is decreasing
4: Suppose you are an ecologist studying the effects of acid precipitation of plant life. Describe an experiment you would perform in order to determine which plant species would be an useful indicator species for acid rain pollution.
I would put different species of plants in separate ecosystems and see the population change over time
5: 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 bar graph shows the population size of the species and the line graph shows How many die sue to the pH change
