Biotic and Abiotic Factors/ Intro to Biomes

Biotic and Abiotic Factors

Ecosystems

Biotic Factors

• Bio means life.

• Any living or once living part of an ecosystem.

• They can be producers, consumers, or decomposers.

Biotic Examples

Producer: Plants

Take energy from the sun to make their own food: Photosynthesis.

Biotic Examples

Consumer: Animals

Some consumers eat producers to gain energy. Some consumers eat other consumers to gain energy.

Biotic Examples

Decomposers: Fungi

Decomposers consume once living things to recycle their nutrients back into the ecosystem.

Abiotic Factors

• No life cycle - Abio means never alive!

• Any nonliving part of an ecosystem.

• Directly affect the survival of biotic factors.

Abiotic Example

Water: Everything alive on Earth needs water to live. Water is not alive.

Abiotic Example

The Sun: Provides energy to the Earth and impacts most living things. The Sun is not alive.

Abiotic Example

Earth: Everything alive depends on the Earth, but the Earth itself is not alive.
