Below is a graph presented in a scientific paper on flight energetics in African Great Pelicans that are gliding by themselves, 14 flapping by themselves at different heights, or traveling in a V formation. (10 marks total) per minute Wing beats 2 . per minute Heart beats Chilling Alone if Alone at In formation a. What is the wingbeat frequency (in wingbeats per minute) of a pelican leading the V formation? (1 mark) b. What is the most efficient and what is the least efficient method of flight for a pelican and how did you conclude this from the data? (3 marks) C. This work is based on optimality theory if the: (1 mark) n-2794984-17
