The science that deals with the relationships between living organisms with their physical environment and with each other.economicsbiologyecologychemistry

The correct answer to the question is ecology.

Explanation:

Ecology is the branch of science that studies the interactions between living organisms (such as plants, animals, and microorganisms) and their physical environment, including the relationships among organisms within these environments. This field encompasses numerous factors, such as climate, soil, and other abiotic components, as well as biotic factors like relationships between species, food chains, and ecosystems.

In contrast:

• Biology focuses more broadly on the study of life and living organisms.
• Chemistry deals with the composition, structure, properties, and change of matter.
• Economics is concerned with the production, consumption, and transfer of wealth.

Ecology specifically targets the interactions and systems involving organisms and their environments, making it the most suitable answer in this context.
