A field planted with rice in their late vegetative stage infested with golden applesnailsc. A field planted with rice in their reproductive stage infested with stemborers5.1 In which situation will lowest yield be obtained and why?5.2. Using the same situations in #5, what will give the highest yield and why?Please select all of the answers that are reasonable interpretations of this figure looking at the mortality of seedling vs the mass of seeds for different species. A. The chestnut blight caused chestnuts to make heavier seeds than any other species B. The proportion of seedlings that survive is better in trees with large seed mass C. There a appears to be a tradeoff. Species that invest a lot of resources into an individual seeds produce fewer seeds that survive well. Species that invest resources in and produce a larger number of lighter seeds produce seedlings with greater probably of dying D. It appears that early-mid successional trees invest more heavily in the number of seeds than the size of seeds E. The proportional survival of tree seedlings is higher in less heavy seeds F. It appears that late successional shade tolerant trees invest more heavily in the number of seeds than the size of seeds1.

The introduction of the parasitic wasp A. melinus in 1957-59 to control the red scale pest resulted in the elimination of the parasitic wasp A. lingnanensis from the central valley of California but not from coastal areas. This pattern results from… a. a lack of resource partitioning between the two species of wasp b. differences in the realized niches of the two species of wasp c. similar habitat in the central valley and in the coastal areas d. None of these choices are correct e. differences in the fundamental niches of the two species of wasp27. The wetland plant purple loosestrife was imported to North America from Europe. Since its introduction, the loosestrife has spread, which has resulted in a dramatic decline in the biological diversity of native wetland plants and harmed the wetland ecosystem. A likely reason for the spread of the purple loosestrife is that it can A. successfully compete with native herbivores for food B. serves as an excellent food source for native herbivores C. successfully out competes with native plants for space D. prevent the migration of native plants 28. The best term to describe purple loosestrife would be A. non-native B. exotic C. invasive D. parasite 29. In some parts of the world, forests are being cut down and burned to clear land for new homes and new farmland.
