A corn field is harvested and plowed, removing most---but not all---of the vegetation. The field is then abandoned and soon begins to revegetate. (A) Would this be an example of primary or secondary succession? Explain. (B) If the field remains undisturbed, we would expect the plant community to change over time. What changes might you expect? For example, what characteristics might you expect in the early successional species and what characteristics might you expect in the later successional species? For full credit, be sure to explain how the different characteristics are expected to be beneficial at each successional stage.

What is the relationship between a pioneer species and primary succession?         A pioneer species is an invasive species that causes areas to experience primary succession.          There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession.         A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot.          A pioneer species only inhabits areas of primary succession.

When a fire occurs ,clearing a forest ,and then new plants start to grow there it is called _____ succession. On the other hand if you have a brand new rock that plants are growing in for the very first time, that is called _____ succession

Summarize how areas affected by wildfire have bounced back biologically in 2 paragraphs. What are the steps of succession seen (what plants grew in first, second, etc.)? You may also include pictures. (HINT: Pick a CA wildfire from a few years ago so there is documentation to assist you).

Why are early-succession species typically better at dispersing than late-succession species?

The Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River. One early study revealed that species on the river had absorbed pollutants from the water. Select the Pollutant Levels in Tissue, by Species dataset and follow the interactive to graph the data. Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm. The fish species with the highest level was about three times the value of the fish species with the lowest level.The fish species with the highest level was about three…
