What colors are the least absorbed but most seen?
Green and yellow
What is the difference between catabolism and anabolism?
Catabolism breaks down and anabolism builds
Explain the ecological pyramid
It starts with the producers that have 100% energy and then the pyramid goes up multiplying by 10. The primary consumers have 10%, the secondary 1% and the tertiary .1%

What is the photosynthesis formula ?
What is the difference between endothermic and exothermic?
Endothermic absorbs energy and is anabolic
Exothermic releases energy and is catabolic

ATP and NADPH
Explain why water molecules are so important in photosynthesis
It's the source of hydrogen for the sugars
