Which of the following is not an example of interactions between biotic and abiotic factors in an ecosystem?

Biotic factors are living things, while abiotic factors are nonliving parts of the environment, such as light and temperature. Flowers responding to daylight, bears hibernating as winter arrives, and butterflies migrating for winter all involve environmental conditions. Male elk fighting over a female is an interaction between living organisms, so it is not an example of a biotic–abiotic interaction.
