Answer 1

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.
