1) Compare the biodiversity indices to one another. State a claim about the effect of pollution on the biodiversity of the stream ecosystem. Describe how the pollution levels affect the species richness and biodiversity of the stream. Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.
Figure 5. This figure shows the number of individuals of three tree species (Blue Pine, Black Oak, and Rusty Cactus) on a woodlot in eastern Ontario, Canada. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. This woodlot experienced a fire in 1969. That suggests that this figure shows primary succession in this woodlot from 1970 to 2015. options: True False

Which oak will win in competition? O A. red O B. white O C. live O D. swamp
Describe the Island Biogeography Model and how it predicts levels of species richness on ‘islands’. Explain how the model relates to conservation biology and can be used for managing biodiversity?
Sea otters, Enhydra lutris, are predators of sea urchins, Strongylocentrotus franciscanus. Sea urchins, in turn, feed on kelp. A study was conducted to determine the effect that Enhydra lutris has on kelp biodiversity. To do so, three bays that have had sea otter populations for varying amounts of time were assessed. Two different types of kelp were studied: a perennial kelp, Laminaria groenlandia, and other annual kelps. The results are shown in the graph below. Additional studies have illustrated the importance of sea otter populations in kelp ecosystems. In the absence of sea otters, the ecosystem collapses. What role do sea otters serve in this ecosystem? a) Keystone species b) Dominant species c) Competitive exclusion d) Obligate species
What trends are shown in the table?
