Now break it down one by one

Let's start with Ecosystems.

An ecosystem is a community of living organisms (biotic components) interacting with their non-living environment (abiotic components).

• Biotic components include producers (plants), consumers (animals), and decomposers (bacteria, fungi).
• Abiotic components are non-living physical and chemical factors like sunlight, water, temperature, soil, and minerals.

Within an ecosystem, energy flows from the sun to producers, then to consumers through food chains and food webs. Nutrient cycling (e.g., carbon cycle, nitrogen cycle) involves the movement of essential elements between living and non-living parts.
