O exploitative competition O top down trophic cascade O commensalism consumption O mutualism O amensalism apparent competition O interference competition O bottom up trophic cascadeProfessor Michael Crawley conducted an experiment to determine the effects of herbivory on English Oak. He sprayed some trees with insecticide for 4 years to eliminate insect herbivores. Other trees were left alone as a control. Control plants had an average of 8-12% of their leaves damaged by herbivores. He examined the number of acorns (seeds) produced per shoot (or branch), and obtained the following data. Error bars represent standard errors. 1.07 Unsprayed 0.8- Sprayed 0.6- 0.4- 0.2- Acorns per shoot

In a seagrass ecosystem, nutrients restrict primary production under low nutrient (oligotrophic) conditions, while light becomes the limiting factor under high nutrient (eutrophic) conditions. Discuss how this happens with respect to the three primary producers (seagrass, macroalgae, phytoplankton) as the condition changes from oligotrophic to eutrophic.
