204. Energy Flow Through Woodlands

Description

In the exam, there are basically 5 types of questions on this topic. Questions ask you to:

1. Describe how plants obtain solar energy.
2. Do simple calculations on energy flow between trophic levels and calculate efficiency and losses.
3. Explain the terms GPP and NPP and perform simple calculations on these.
4. Explain why focusing on energy flow is more useful than focusing on biomass.
5. Explain how human activities e.g. deforestation alter natural energy flow.

This Environmental Studies Factsheet goes through each of these questions, focusing on deciduous woodlands and tropical forests but the principles apply to all other ecosystems.
