What is a food chain?
Reactant of Photosynthesis that contains carbon
What is carbon dioxide?
Something that is needed by an organism and is not infinite in it's abundance in an ecosystem; once exhausted, the organisms that need it cannot survive

What is competition?
Percent energy that is transferred from organism to organism
What is 10%?
A group of interacting individuals of the same species located in the same area.
What is a population?
something that eats something else for food
What is a consumer?
An organism that feeds on dead and decaying organisms
What are decomposers?
the flow of energy from a producer to one or more consumers. (ie: linked together by their feeding relationships)

Plants use this process to turn light into chemical energy
What is photosynthesis?
The source of energy that is absorbed by plants for photosynthesis.
What is sunlight?
A product of photosynthesis that contains 6 atoms of hydrogen.
What is glucose?
