secondary succession. • Three causes of secondary
succession.

TOPIC/UNIT: 7th: Life/Diversity & Interdependence of Life Time Line: Indicator (# 11): Explain that photosynthetic cells convert solar energy into chemical energy that is used to carry on life functions or is transferred to consumers and used to carry on their life functions.
KNOW
• How cells move particles from region to region.
• Osmosis is the diffusion of water through a membrane.
• During passive transport substances diffuse through proteins.
• During active transport substances are moved from areas of low concentration to areas of high concentration.
