Which term refers to all the conditions and influences surrounding an organism?

The term that refers to all the conditions and influences surrounding an organism is "environment." This encompasses not just the physical aspects such as soil, water, and climate, but also the biological factors, including other organisms that interact with that particular organism. The environment plays a crucial role in shaping the growth, behavior, and evolution of organisms, as it includes both abiotic (non-living) and biotic (living) factors that affect them.

In contrast, "ecology" specifically focuses on the study of interactions among organisms and between organisms and their environment, rather than encompassing all aspects of the environment itself. "Habitat" refers to the specific place or type of place where an organism or community of organisms lives, which is just a component of the broader environment. Meanwhile, "biome" describes large ecological areas on the Earth's surface, characterized by specific plant and animal groups, further defining the conditions within a larger aspect of the environment but not addressing it in totality. Thus, "environment" is the most comprehensive term that includes all the influences surrounding an organism.
