TRANSCRIPT
Biotic and Abiotic Biotic and Abiotic factors in the factors in the EcosystemEcosystem
• Level of organization is used to show how organisms interact with each other & their environment
• Abiotic factors = non-living components that affect living organisms • Ex. Temperature, sunlight, rocks
• Biotic Factors = all living things or their materials that directly or indirectly affect organisms in its environment (includes interactions) • Ex. Plants, animals, fungi, bacteria
• A(n) ___________ factor is a living (or once living) component of an ecosystem.
• A(n) ___________ factor is a non-living component of an ecosystem.

• Do these abiotic factors affect the biotic parts of an ecosystem? How?
If there is no water…can anything grow or survive?
No!
If it is extremely cold one winter, will that affect whether an animal makes it?
No!
So, abiotic and biotic DO affect each other. Even So, abiotic and biotic DO affect each other. Even though water and temperature arenthough water and temperature aren’t living things, ’t living things,
they DO affect living things!they DO affect living things!

• What abiotic factors are important for a plant to grow?
• Provides warmth to living organisms• Provides solar energy (light) for green plants to make
their own food• The number of hours of daylight triggers seasonal events,
such as: -plants flowering -birds migrating
• Important for life processes of all living things (plants and animals) such as:
-distributing food particles through their bodies -digesting food• Important for organisms that live under water, such as: -trout -whales -algae
• Provides oxygen (O2), which animals breathe
• Provides carbon dioxide (CO2) for plants to use to make their own food
• Provides a home for many animals that live underground -earthworms
• Provides nutrients for plants
• Plants grow in soil
