In a well-constructed essay, describe why biodiversity increased with the introduction of sea otters in California over the last fifty years? Make sure to organize your thoughts using paragraphs. Try to use your best grammatical skills and refrain from using “it” or
bullets. For each claim on why biodiversity increased, support your argument with evidence. Tables, graphs, or pictures may be used
to illustrate your discussion, though points will only be given to the narrative portion of your discussion. Use only the front of the
page for your narrative and if needed the back only for graphics.

75 POINTS

Sea otters affected biodiversity because they control the populations of sea urchins, which endanger kelp forests. Kelp forests are important because they convert sunlight to living material, and they also provide food and habitat to sea creatures. Kelp is important in sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable for the large size of abalones in California.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
