What is the acronym for the study of living organisms and their environment?

  1. Biodiversity

  2. Ecology

  3. Earth Science

  4. Environmental Science

The correct answer is: Ecology

Ecology is the study of living organisms and their environment, while biodiversity specifically refers to the variety and distribution of life on Earth. Earth Science and Environmental Science are more umbrella terms that encompass a broader range of scientific studies, rather than being specific to living organisms and their environment.
