Ecology is the branch of biology that focuses on these interactions, including:
* How organisms interact with each other (predation, competition, symbiosis)
* How organisms interact with their physical surroundings (temperature, water availability, sunlight, soil)
* How these interactions shape the distribution and abundance of organisms
* How ecosystems function and change over time
Ecologists use a variety of methods to study these interactions, including field observations, experiments, and modeling. They play a crucial role in understanding how ecosystems work and how human activities are impacting the environment.
