Plants change their surroundings
Biotic parts shape abiotic parts.
Give and take
Living things use air, water and soil. They also change them.
What do plants release during photosynthesis?
What this lesson covers
The idea
Abiotic components are also influenced by biotic ones: plants release oxygen in photosynthesis, their roots hold soil and prevent erosion, and they retain soil moisture and help cool the atmosphere.
Give and take

What do plants release during photosynthesis?
- Oxygen
- Soil
- Sunlight
What plants do
Open each tab.
Both ways
Just as biotic components depend on abiotic components, abiotic components are also influenced by biotic components.
Biotic components also influence abiotic components: plants release oxygen, roots hold soil and prevent erosion, and plants retain soil moisture and help cool the atmosphere.
Notes
Biotic parts also change abiotic parts: oxygen, soil held by roots, moisture, cooling.
