Study Notes

Definition of an Ecosystem

An ecosystem is a community of living organisms interacting with their physical environment.

Abiotic Components of an Ecosystem

Abiotic components include non-living factors such as water, sunlight, air, soil, temperature, and minerals.

Classification of Biotic Components

Biotic components can be classified into three main categories based on the source of food:
- Producers (autotrophs)
- Consumers (heterotrophs)
- Decomposers (saprotrophs)

Examples of Ecosystems

Various ecosystems include forests, deserts, grasslands, and aquatic environments.

Ecosystem Functions

Ecosystem functions encompass processes such as nutrient cycling, energy flow, biomass production, and habitat provision.

Non-Abiotic Component

Any factor that is living or organic, such as plants, animals, or microorganisms, is not classified as an abiotic component.

Ecosystems Not Mentioned

Ecosystems such as tundras or coral reefs were not specifically mentioned.

Main Function of Saprotrophs

Saprotrophs play a crucial role in breaking down dead organic matter, recycling nutrients back into the ecosystem.

Highly Biodiverse Ecosystem

Rainforests are characterized by high biodiversity and receive abundant rainfall, contributing to their diverse life forms.
