1. Biotic factors: These are the living components of an ecosystem, including:

* Plants: Producers that provide food and oxygen.

* Animals: Consumers that feed on other organisms.

* Fungi and bacteria: Decomposers that break down dead organisms and waste.

2. Abiotic factors: These are the non-living components of an ecosystem, including:

* Sunlight: Provides energy for producers.

* Water: Essential for life processes.

* Temperature: Affects the rate of biological processes.

* Soil: Provides nutrients and support for plants.

* Air: Provides oxygen for breathing.

These two parts are interconnected and rely on each other for survival.
