Overview
Ecosystem analysis is the systematic study of interactions and processes that control ecosystem structure, functioning, stability, and response to disturbance. An ecosystem is an interconnected and self-regulating system formed by interactions between living components such as plants, animals, and m
Key Concepts
The systematic study of interactions
The systematic study of interactions and processes that regulate ecosystem structure and functioning. It focuses on relationships, feedback mechanisms
An ecosystem has biotic components
An ecosystem has biotic components, which include producers, consumers, and decomposers, and abiotic components, which include sunlight, water, air, s
Abiotic factors control the growth
Abiotic factors control the growth, distribution, and survival of organisms, while living organisms also modify abiotic conditions by adding organic m
A limiting factor is any environmental
A limiting factor is any environmental condition that restricts the growth, abundance, or distribution of an organism or population. Limiting factors
Growth is determined not by total
Growth is determined not by total resource availability but by the resource present in the least amount.
