Why does the presence of invasive species generally result in a decrease in biodiversity of native species in an area?

a.) invasive species are invasive because they release toxic compounds into the environment, killing native species.

b.) invasive species lack natural predators and quickly outcompete natives for food and shelter.

c.) invasive species naturally thrive in low biodiversity habitats because even their native habitat is low biodiversity.

d.) the only way to get rid of invasive species is to use pesticides, which kills both invasive and native species.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

Based on the law of dominance, we would expect percent of the offspring from this cross to have large teeth.
