GCSE Science/Ecology

Definition
Ecology is the scientific study of the interactions among organisms and the interactions between the organisms and their environment. Every living organism and component of an environment cannot exist as a separate entity. Instead, they are interrelated and form a complex system.

Components of ecosystems
An environment consists of living organisms and non-living organisms. The living organisms in an environment are called the biotic components and the non-living factors are called the abiotic component. The biosphere is where this organism exist in.
