Which term describes the branch of biology that studies the relationships of organisms with their environment?

Explanation:
Understanding how living things interact with their surroundings is ecology. This field looks at how organisms relate to each other and to the physical world—climate, soils, water, and resources—and how these interactions shape where organisms live, how they survive, and how ecosystems function. Ecologists study energy flow, nutrient cycles, and how populations and communities respond to environmental changes, from a single organism to entire ecosystems. That focus on relationships with the environment is why ecology fits best here. Other options describe different ideas: population ecology centers on how populations rise or fall in size, phylogenetic trees map evolutionary relationships rather than environment, and specialists isn’t a biology subfield.
