Guys i need with biology 1 i don’t understand what the independent and dependent is nor the what causes or what changes! can anyone ?

5) air temperature - corn sprouting time

6) sacks of fertilizer sold - algae growth

7) cars - pollution levels (sorry couldn't read the full problem, but you get it)
