Ecosystems
An ecosystem is a community of living organisms interacting with each other and their physical environment, forming the fundamental units of study within ecological science.
Functioning as intricate webs of interdependence between living organisms and their physical surroundings, these ecological communities reveal how removing even a single species can trigger consequences throughout an entire system.
Living Communities and Their Environment
An ecosystem encompasses both the living organisms within a particular area and their interactions with the surrounding physical environment, including climate, soil, and water.
Energy Flow Through Food Webs
Ecosystems are organized around food webs, describing how energy flows from producers like plants through various levels of consumers and eventually to decomposers.
Keystone Species
Certain species, known as keystone species, play a disproportionately significant role in maintaining their ecosystem's structure, with their removal potentially causing dramatic cascading effects.
Vulnerable to Disruption
Ecosystems can be significantly disrupted by human activities including habitat destruction, pollution, and the introduction of invasive species, underscoring the importance of conservation efforts.
