In the experiment shown below, Balanus was removed from the habitat shown below. Connell conducted this experiment to learn more about a. Character displacement in the color of barnacles b. Habitat preference in two different species of barnacles c. Desiccation resistance and barnacle species d. How sea-level changes affect barnacle distribution e. Competitive exclusion and distribution of barnacle species EXPERIMENT Ecologist Joseph Connell studied two barnacle RESULTS Chthamalus spread into the region formerly species-Chthamalus stellatus and Balanus balanoids - that have a stratified distribution on rocks along the coast of Scotland. 6. Consider the global nitrogen cycle. Which of the following statements best describes how humans are altering this cycle? a. Humans have dramatically increased the amount of nitrogen in the deep ocean reservoir by polluting surface run-off waters with fertilizer. b. The amount of denitrification has been accelerated due to intensive agriculture, thereby increasing the nitrogen concentration in the atmosphere. c. Humans have dramatically reduced the amount of nitrogen available to terrestrial ecosystems tying up nitrogen in fertilizers. d. Humans have accelerated the rates of internal nitrogen cycling in both terrestrial and marine ecosystems. e. The combination of industrial nitrogen fixation and biological nitrogen fixation by crops now exceeds natural rates of biological nitrogen fixation.
