Biomass Productivity
Aim-
The aim of this experiment is to determine the productivity of a piece of grass within a five week period.
Hypothesis –
I think the productivity of the grass will show a gradual increase over the weeks that we measure it, because the grass it photosynthesizing all the time thus increasing in mass. Photosynthesis is a process by which green plants use the light energy to convert carbon dioxide and water into the simple sugar glucose.
Variables
Controlled
- Area of sample
- Time between each measurement
Independent
- Different sections within the bounded area.
