Explanation:

Ecology is a branch of biology that focuses on the interactions between living organisms (such as plants, animals, and microorganisms) and their physical and biological environments. This includes how organisms interact with each other (e.g., predator - prey, symbiotic relationships) and with non - living components like soil, water, and air.

• The option "the relationships between parasites and their hosts" is too narrow as it only focuses on one type of interaction (parasitism) within a much broader field.
• "Plant succession" is a part of ecological studies (it's about the process of change in the plant species composition in an area over time), but it does not define the entire field of ecology.
• "Interactions between predator and prey populations" is also a specific type of interaction within the larger scope of ecological studies.

Answer:

the interactions between living organisms and their environments
