Photosysnthises Flashcards
If we didn’t have photosynthesis what would happen
Most life on earth would not exist
Organisms that photosynthesize make their own…
Make their own energy rich food components using light energy
Do you organisms that make their own food are called
Producers
What are major producers on land
Green plants. The green color comes from a chemical called Chlorophyll which captures light energy.
The equations for photo synthesis are.
Word equation – carbon dioxide + water+ light energy-> sugar (glucose) + oxygen
Chemical equation – co2 + 6H2o + light energy -> c2h12o6 + 6 o2
What is cellular respiration
Cellular respiration is a chemical process in which energy is released from food. In the process the sugar and oxygen are rearranged to form carbon dioxide and water. As this reaction takes place energy is released. Cellular respiration occurs in all living organisms.
What is photosynthesis
It is a chemical process in which sunlight energy is captured and converted into chemical energy the conversion of energy is one of the most important chemical processes
What are organisms that cant photosynthesize or make their own energy rich sugar.
These organisms are called consumers, they get their energy and building materials by eating other organisms
How much energy does a consumer get from another animal
Usually about 10%. Around 30% is lost as body heat, 60% is not absorbed at all and goes out in feces.(calories- 1000kj of grass is 100kj of rabbit meat and so on)
