Ecological systems, or ecosystems, are dynamic complexes of plant, animal, and microorganism communities interacting with their physical environment as a functional unit. They are characterized by energy flows and nutrient cycles, supporting biodiversity and services essential for life on Earth.

Ecosystems are complex networks of living organisms and their physical environment, interacting as a system through nutrient cycles and energy flows. They can vary greatly in size and complexity, from a small pond to an entire forest, and are crucial for maintaining biodiversity and ecological balance.

A Functional Unit is a specific component or entity within a system that performs a distinct function or set of functions, often used to measure and compare the efficiency and performance of processes. It is crucial in systems analysis and life cycle assessment to ensure consistent and meaningful comparisons between different systems or products.

Nutrient cycles are the natural processes that recycle essential elements such as carbon, nitrogen, and phosphorus through the environment, organisms, and back to the environment. These cycles are crucial for maintaining ecosystem health and productivity, as they ensure the continuous availability of nutrients required for various biological processes.

Biodiversity refers to the variety and variability of life on Earth, encompassing the differences within species, between species, and among ecosystems. It is crucial for ecosystem resilience, human survival, and provides numerous ecological services, yet is threatened by human activities such as habitat destruction, pollution, and climate change.
