Question
Chapter 5.7, Problem 2MC
Summary Introduction
To identify:
A standardized variable, an independent variable, and a dependent variable in the experiment.
Concept introduction:
Photosynthesis is a process that converts carbon dioxide and water into glucose and oxygen using the energy from sunlight. The products of the photosynthesis cab be used directly by the plants or can be transferred to other organisms which feed on plants or breakdown into dead plant material.
