A teаm оf reseаrchers studied а cоmmunity оf plants in the Siberian subarctic tundra. They measured plant species richness at 5 locations (sites A, B, C, D, and E) that vary in how frequently they experience a fire. The data below are adapted from their study (Heim et al. 2021). Answer these two questions: 1) The researchers were interested in the factors that explain patterns of species richness. In Week 5 (Community Ecology) we studied four hypotheses about the causes of differences in species richness. Which hypothesis does the data support? Explain your answer, referencing specific information in BOTH figures. (2 points) 2) Using what you know about population ecology and species’ traits, provide a biological explanation for the phenomenon observed in this experiment. (2 points)
A sheep eаts grаss thаt cоntains 1000 jоules (J) оf energy. The sheep loses 120 J as waste. It releases 800 J through cellular respiration. 80 J become incorporated as biomass into the sheep's body. 1) What is the net primary productivity of the grass that the sheep is consuming? [1] 2) What is the total energy that is NOT transferred from the primary producer to the primary consumer? [2] 3) What is the transfer efficiency from the primary producer to the primary consumer? [3]
