Reflection Journal – Chapter 18 Primary and Secondary Production

Source Textbook: Ecology: Concepts & Applications by Manuel Molles (2013) Tasks to Address: Review 18.1 (pages 393–395): Define gross primary production, net primary production, secondary production, and trophic level. Describe the relationship between evapotranspiration and net primary production in terrestrial ecosystems. Provide the evidence showing that nutrient availability can limit primary production in terrestrial ecosystems. Review 18.2 (pages 396–398): Summarize the main factors limiting primary production in aquatic ecosystems. Outline the types of evidence used to demonstrate nutrient limitation of primary production in aquatic ecosystems. Review 18.5 (pages 405–409): Define ecological efficiency, including the ranges of ecological efficiencies found in nature. Discuss the influence of enrichment of primary production on secondary production by primary consumers and predators.
