Question

Submit Q1.23. Late each summer, migrating rufous hummingbirds stop in Arizona, where they establish and defend territories. Larger territories contain more flowers, provide more energy in the form of nectar, and are harder to defend. Researchers Astrid Kodric-Brown and James Brown developed a cost- benefit model to help explain observed variation in territory size (S). A modified version of their model is shown to the right. Based on this model--and assuming optimal behavior-how large an area should a hummingbird defend (referring to labels on the x-axis)? Si S2 S3 SA

Answer 1

Inverse of Exponential fenn. Auswers- option (52) 2nd corrent Explanations As seen Hom the graph the cost increase in an Exponnutial manner and benefit in an the cost Keep increasing The balance of cost and benefit is bound to be best at S2. Ats, with minum Cost we get manimum benefit. As we move further on onto So the benutit remains same although When looking acto S4 cost as greater than the benefit. So considering all options S2 is the best choire. Answer please fate my
