2. Would a sea otter catch these prey items alone or with help from others? Using the quantitative data provided in
Table 1 below, prove which method of hunting your sea otter must utilize to obtain its daily energy needs. You
will answer this question on the next page when you complete your Claim-Evidence-Reasoning but you must first
work out the math below. Using the "observed sea otter diet" above, calculate the energy consumed to
determine if it satisfies this female's daily needs.
