Sep 20, 2006 · A direct relationship between ecosystem structure and function has been widely accepted by restoration ecologists. According to this paradigm, ecosystem degradation and aggradation represent parallel changes in structure and function, restoration following the same path as spontaneous succession.

Module 23 : Structure and Functions of Ecosystems. Learning Objectives.

A conceptual model describes ecosystem structure and dynamics and shows how environmental disturbances affect the ecosystem; however, its ability to predict the effects of these disturbances is limited.

We define an eco-system model as a model that describes the interactions between at least two ecosystem components (for example, a species or func-tional group), whereby the interactions are real ecological processes (for example, predation, dispersal or perturbations).

An ecosystem is, therefore, defined as a natural functional ecological unit com•prising of living organisms (biotic community) and their non-living (abiotic or physio chemical) environment that interact to form a stable self-supporting sys•tem.

What is an Ecosystem? The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interaction between organisms and their environment. The term “Ecosystem” was first coined by A.G.Tansley, an English botanist, in 1935.

Concept of ecosystem •Ecosystem (A.G. Tansley, 1935) is a self regulatory and self sustaining structural and functional unit of landscape consisting of community of living organisms (plants, animals, and microbes) interacting with each other and their non-living environment (air, water, and soil). •Importance:

Apr 29, 2025 · Conceptual models provide a qualitative framework for understanding ecosystem structure and function. Using diagrams, flowcharts, or simplified mathematical representations, they illustrate key ecological processes and interactions.

We review models used in recent global model intercomparison projects and develop a novel model integration framework to more fully account for the role of biodiversity in ecosystem function, a key gap for linking biodiversity changes to ecosystem services. We propose two integration pathways.
