Ecology is the science that studies the biota (living things), the environment, and their interactions.It comes from the Greek oikos = house; logos = study.. Ecology is the study of ecosystems.Ecosystems describe the web or network of relations among organisms at different scales of organization. Around this time, European and American scientists began studying how plants functioned and their effects on the habitats around them. Changes in ecosystems can result from many different factors including diseases among the organisms living in the area, increases in temperature, and increased human activities. Today, modern ecologists build on the data collected by their predecessors and continue to pass on information about the ecosystems around the world. It assigns roles to us and insists on our playing them. Graduate student Christina Bielski recorded data during a high intensity prescribed fire burning through juniper-invaded grassland on private property.

Individual species are related to various adaptations like physiological adaptation, morphological adaptation, and behavioural adaptation. What do organisms need to survive and thrive in their current environments? These kinds of organisms are called invasive species. These complex interactions lead to different selective pressures on organisms. Human ecology is a term that describes the interaction of human beings with their ecosystem. Organismal ecology is the study of an individual organism’s behaviour, morphology, physiology, etc. Ecology - Ecology - Areas of study: Ecology is necessarily the union of many areas of study because its definition is so all-encompassing. National Geographic Headquarters The pressures together lead to natural selection, which causes populations of species to evolve. Understanding these changes can help ecologists anticipate future ecological challenges and inform other scientists and policymakers about the challenges facing their local ecosystems. For example, the Pacific Yew tree produces a substance which is used in cancer treatments. The more natural an ecosystem is, the more ecosystem services it provides.
