Energy pyramid

A

Graphical representation to show the relationship between energy and trophic levels of a given organism

19
Q

Trophic level

A

The position that an organism occupies in a food chain~ what it eats and what eats it

20
Q

Photosynthesis

A

Conversion of suns energy to chemical (food/glucose) energy

21
Q

Cellular Respiration

A

Process by which chemical bonds (food/glucose energy) are concerted to usable energy (ATP)
~ C6H12O6 + 6O2 -> 6CO2 + ATP
