A. Read pages 87-89 and answer Questions pages 115-116: 1-3, 11-12. Due 9 November.
Terms & Concepts: Distinguish between the terms "weather" and "climate." Understand that climate has a long term effect on the composition of ecosystems around the globe. Be able to discuss the greenhouse effect as an example of the dramatic influence of climate on the biosphere. Be able to list and describe the three major climatic zones of the globe, polar, temperate, and tropic and their relationship to latitude. Be able to interpret the maps on page 89 in terms of the global movement of heat energy and its relationship to solar heating. Here is a link for an excellent video animation of global ocean currents.
B. Read pages 90-97 and answer Questions pages 115-116: 4-7, 13-16. Due 14 November.
Terms & Concepts: Review the concept of biotic and abiotic factors of an ecosystem. Understand the important interrelationships between these two elements of the ecosystem and their role in the growth and survival of organisms. Appreciate the important concept of the "ecological niche." Understand the relationship of an organism's niche and the biotic and abiotic factors of its ecosystem. Be able to describe the classic study of warblers as an example of how similar species can live together in the same ecosystem by having specialized niches. Be sure you now what the terms competition and predation mean in terms of the use of ecosystem resources. Be able to state and give examples of the competitive exclusion principle. Understand how symbiosis describes the close and often obligatory relationships among species including mutualism, commensalism, and parasitism. Be able to give examples of each of these types of symbiotic relationships. Appreciate that ecosystems are not fixed relationships of species. Ecological succession is the natural progression of change in ecosystems. Distinguish between primary and secondary succession and be able to describe examples of succession in desert, forest, and marine ecosystem.
C. Read the article "Warmer and Weedier" from Natural History magazine and answer these Questions. Also Questions pages 115-116: 30 and 33. Due 16 November.
D. Read pages 98-105 and answer Questions pages 115-116: 8, 17-20, 27. Due 21 November.
Terms & Concepts: Be able to define biome in relationship between abiotic and biotic factors and the unique groups of organisms that live in each biome. Understand the critical role of temperature and precipitation in determining the characteristics of a biome. Be able to interpret the "climate diagram" such as figure 4-10 on page 98. Be able to use the global map on page 99 to identify the location of the major biomes. Use the information on pages 100-104 to know the important characteristics of the major biomes in particular the abiotic factors, dominant plants and animals, and location.
E. Read and Summarize the article "Tiny Conspiracies" from Natural History magazine. Use the posted writing guide to help organize and format your work. Due 23 November.
F. Read pages 106-112 and answer Questions pages 115-116: 9-10, 21-25, 28. Due 28 November.
Terms & Concepts: Use the information on pages 106 to 112 to know the major aquatic and marine biomes. Be able to describe the abiotic and biotic elements of these biomes and their dominant plants and animals, and their locations.
