How photosynthesis makes food
Autotrophs are organs that can make their own food (chemical energy)
Photosynthesis organism use the energy from the sun to convert C02 and h20 into sugars
and 02
Heterotrophs are organism organism that don’t have this abuity and must ultilize the chemical
energy provided by the producer

Photosynthesi: Using Light to make food
Autotrophs are the producers of the biosphere
1. Autotrophs
a. Make their own food through the process of photosynthesis (Chemical energy)
b. Sustains them
Why are plants green?
Plants are filled with chlorophyll, which gives plants their green hue. Chlorophyll is a
photoreceptor and traps light, absorbing energy to transform water and carbon dioxide to produce
sugar and oxygen following photosynthesis:
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
This allows them to convert energy from the sun into food for themselves. It is found in every
single plant on Earth, from mosses to evergreens, and has only evolved once.
Photosynthesis occurs in chloroplasts in plant cells
Chloroplasts are the major sites of photosynthesis in green plants.
Cellular Respiration is exergonic = release energy
Photosynthesis is endogonic = require energy
