A sample from this course

One topic, as StudyPath teaches it.

Photosynthesis, combustion and respiration, nutrition, and digestion, circulatory system

This topic brings together four life processes that keep organisms alive: how plants make food by photosynthesis, how energy is released by respiration and compared with combustion, how organisms obtain and break down food through nutrition and digestion, and how materials are transported by the circulatory system.
