Discuss the difficulties of classifying organisms into trophic levels. 7. Explain the small biomass and low numbers of organisms in higher trophic levels. 8. Discuss how the high-meat diet of the developed world (which is aspired to by many developing nations) may be speeding our approach of the planet’s carrying capacity for humans, and some of the steps that can be taken to reduce this effect. 9. Describe what is meant by ecological succession. 10. Distinguish between primary and secondary succession, with examples: Primary Secondary Explanation Example 1: Example 2: Stephen Taylor Bandung International School http://sciencevideos.wordpress.com Essential Biology G2 Ecosystems & Biomes Due Date: Student Name: Candidate Number: 002171-xxx 11.
