Respuesta :
Young European flycatchers hatch from eggs when caterpillar biomass is available for the young birds to consume and convert into energy for growth is the statement that justifies this claim the best.
What is the European Flycatcher's habitat?
The Old-World flycatcher family includes the little passerine bird known as the European flycatcher. It hybridizes to a limited extent with the collared flycatcher, one of the four species of Western Palearctic black-and-white flycatchers. It reproduces throughout Western Palearctic and the majority of Europe. It migrates, spending most of its winters in tropical Africa. Typically, it creates its nests inside of holes in oak trees.
What kind of reproduction habits does the European Flycatcher have?
The male of this species frequently engages in bigamy, or polygyny, by traveling great distances to find a second partner. In order to assist with parts of infant raising, such as feeding, the male will mate with the secondary female before returning to the primary female.

The given question is incomplete. The complete question is:
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. Female European flycatchers require energy to lay eggs, so they lay their eggs when the caterpillar biomass is maximal.
D. The energy requirements for hatching European flycatchers and caterpillars are proportional to each other.
