Question

the picture shows a forest environment with a stream passing through it. which of the following is an nonliving factor interacting with a living factor in this forest environment? a. the stream, as it provides a place for the fish to swim b. the large tree, as it provides a home for birds and squirrels c. the fallen tree trunks as they decompose into the soil d. the small fern plants, as they provide food for insects

Explanation:

• Option A: The stream is a non - living (abiotic) factor and fish are living (biotic) factors. The stream providing a place for fish to swim shows an interaction between a non - living and a living factor.
• Option B: The large tree is a living factor (biotic), and birds and squirrels are also living factors. This is an interaction between living factors.
• Option C: The fallen tree trunks are dead organic matter (biotic, even though they are no longer alive, they were part of a living organism). The soil has both biotic (e.g., soil organisms) and abiotic components, but the decomposition of tree trunks (biotic) into soil is more of a biotic - biotic or biotic - abiotic (if considering non - living parts of soil) interaction where the main focus of the tree trunk is its biotic origin.
• Option D: The small fern plants are living (biotic) and insects are living (biotic). This is an interaction between living factors.

Answer:

A. the stream, as it provides a place for the fish to swim
