13 European flycatchers feed caterpillars to their hatchlings Graph 1 shows the average dates of hatching and fledging leaving the nest and the biomass of the caterpillars between early May when flycatcher young hatch and June when fledging of young occurs Frequency Biomass of Caterpillars Date of Hatching Date of Fledging GA June 2 Peak Mass May 15 Hatching Hatchling Food Needs Pupae May 28 Graph 1 Comparison of European flycatcher hatching and fledging dates and caterpillar biomass Based on the data scientists claim that the reproductive behavior of European flycatchers is influenced by the availability of energy sources Which of the following statements best justifies this claim a Young European flycatchers hatch from eggs when caterpillar biomass is available for the young birds to consume and convert into energy for growth b European flycatcher hatchlings begin to need energy to leave the nest only after the caterpillars have turned into pupae c d The energy requirements for hatching European flycatchers and caterpillars are proportional to each other Female European flycatchers require energy to lay eggs so they lay their eggs when the caterpillar biomass is maximal
