AP BIOLOGY

Detailed explanation-1: -An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.

Detailed explanation-2: -Every ecosystem is composed of two basic units: a) Biota: the living organisms-all plant & animal species. b) Abiotic: the non-living physical and chemical component consisting of wind, temperature, water, soil, precipitation etc.

Detailed explanation-3: -An ecosystem is a community of organisms and their physical environment interacting together. Environment involves both living organisms and the non-living physical conditions. These two are inseparable but inter-related. The living and physical components are linked together through nutrient cycles and energy flows.

Detailed explanation-4: -It consists of populations of interacting species. Types of community interactions are predation, competition, and symbiosis. Predation is a relationship in which members of one species consume members of other species. Predation influences population sizes and co-evolution of predator and prey species.

Detailed explanation-5: -These are called ecosystems. Ecosystems vary in size. They can be as small as a puddle or as large as Earth itself. Any group of living and nonliving things interacting with each other can be considered as an ecosystem.
