Draw a pyramid of energy for an ocean ecosystem where phytoplankton are consumed by zooplankton which are eaten by sardines which are consumed by otters. The phytoplankton contain 80,000 J of energy. How many trophic levels are in the food chain described in question 3? Explain why there is a loss of energy at the higher levels. Study the following food web. Describe all the population changes that would occur if a new species of frog entered the ecosystem. a pesticide killed all the birds. 11. a) Draw the carbon cycle. b) Classify each process as a carbon sink, a carbon source or a neutral process. 12. The three processes of the carbon cycle that humans have had the greatest impact on are combustion of fossil fuels/biomass, the dissolving of carbon dioxide into the oceans, and the process of photosynthesis. Explain how humans impact each process and why it is causing a problem in terms of sustainability of ecosystems. 13. a) Explain why Asian carp are considered to be an invasive species. b) Which of the five requirements for a sustainable ecosystem would be affected by the introduction of Asian carp to the Great Lakes? Describe how these requirements are affected. 14. Throughout this unit, we considered the following human impacts on ecosystems of our world: Human Impact #1 Deforestation Human Impact #2 Large Scale Meat Production Human Impact #3 Plastics A Consumer Product – Human Impact #4 Invasive Species For each of these human impacts: a) Discuss how this activity affects the lithosphere, the hydrosphere, the atmosphere, and the biosphere. b) Describe how this activity can make ecosystems unsustainable by its impact on the five requirements for a sustainable ecosystem. c) Describe two possible solutions or alternative practices that would reduce its impact. This is only a list of topics. See the test review for questions. Space Unit - Knowledge Topics – Big Bang Theory and evidence. Formation of Stars- life and death, different types of stars. Our Solar System- Solar Nebula Theory. Properties of planets- atmosphere and distinguishing characteristics for each, comparison of inner terrestrial and outer Gas Giants. Celestial Bodies and Eclipses. Triangulation to space Canada’s contribution Galaxies.
