Question

many of the processes that occur in the natural world involve interactions between matter and select one: a. energy. b. space. c. time. d. airflow.

Explanation:

In natural processes (like chemical reactions, physical changes, biological activities), matter interacts with energy (e.g., energy transfer in photosynthesis, heat in phase changes). Space, time, or airflow aren't fundamental interaction partners for matter in most natural processes as energy is.

Answer:

a. energy.
