AP Biology· difficulty 4/5
A life table for a hypothetical organism shows survivorship (l_x) and fecundity (m_x) by age.
The net reproductive rate R0 = sum(l_x * m_x) for this cohort equals approximately:
0.50
3.50
6.00
1.65
Explanation
R0 = (1.00)(0) + (0.50)(2) + (0.20)(3) + (0.05)(1) + (0)(0) = 0 + 1.00 + 0.60 + 0.05 = 1.65.
