Which field studies the dynamic relationship between a community of organisms and its habitat?

The correct answer is ecology. Ecology is a branch of biology that focuses specifically on the interactions between living organisms, including humans, and their physical environment. It examines how organisms adapt to their habitats, the relationships within and between communities, and the factors that influence their distribution and abundance.

Ecology is concerned with the dynamics of ecosystems, which include both biotic (living) and abiotic (non-living) components, and how these interactions shape the environment. This subfield encompasses various levels of study, such as population ecology, community ecology, and ecosystem ecology, making it a comprehensive discipline dedicated to understanding the complexities of life as it relates to the environment.

While geology studies the Earth and its physical structures, biology is a broader field that encompasses all forms of life, and botany specifically focuses on plants. These fields, though essential in their own right, do not concentrate primarily on the intricate relationships between organisms and their habitats as ecology does.
