• 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
