Key Points

Here is a brief explanation about an ecosystem:
Interaction of Life and Non-Life:
- An ecosystem is a community of living organisms (plants, animals, microbes) interacting amongst themselves and with their non-living surroundings (atmosphere, earth, sun, soil, climate).
Energy Flow:
- The ecosystem is characterized by the flow of energy and matter through food chains and food webs.
- It starts with the energy from the sun being captured by plants in the process of photosynthesis.
Nutrient Cycling:
- In an ecosystem, nutrients are cycled through various living and non-living components.
- This involves processes like decomposition and nutrient absorption by plants.
Different Types:
- Ecosystems can vary widely in size and characteristics, from a small pond to a large forest or even an entire biome such as a desert or tundra.
Balance:
- Ecosystems inherently maintain a balance between different species and resources.
- However, human intervention or natural disasters can disrupt this balance, affecting the entire ecosystem's functionality.
Here is a simple illustrating the structure of an ecosystem:
