What is another source of energy besides the sun that gives plants energy to grow?

im in gr7 an i have a scince project (in french..) an we have to make a food chain with 4 organisms + an energy source besides the sun then we have to explain why we chose that energy source instead of the sun..

What is another source of energy besides the sun that gives plants energy to grow?
I would look into information about the deep-water vents. They provide the energy for some very unique deep ocean habitats. I provided a link below.





You may also look into cave habitats. See the second link below.





Both of these environments are completely devoid of sunlight but provide very unique food chains.





An easier idea would be to just take any portion of the food chain (perhaps starting with grass or insects) since they are both a source of energy for the animals above them.
Reply:u can use light. from mentol or such. it can be one of the energy source too. search for light + chlorophyl in the internet *wikepedia for instance* tp get better and detail understanding. happy experimenting dear =)
Reply:all sources of energy on earth originate from our sun.





apart from that:





no sun, no solar system.





no solar system, no planet earth...
Reply:breath/hydrogen
Reply:Plants PRODUCE energy by the process of photosynthesis.


Sunlight is essential for that process to work.


All energy comes from the sun.


Plants get nutrients from minerals in the soil.


You can use artificial light to grow plants.


Artificial lights are used to grow plants indoors for instance, or in places where the tempatures are harmfull to plants.


Another place artificial light would be used is in spacecraft


or places on earth that for one reason or another get little natural sunlight.
