- In 1929, 13 white-tailed deer were introduced to an isolated island with no natural predators. A survey was conducted once a year to estimate the population of deer on the island. The table shows the deer population over the first five years on the island. The deer fed on many of the native plants found on the island, including the California false indigo, a thornless shrub that is a preferred food source on the island for deer. Based on the data, which of the following graphs correctly predicts the population of California false indigo from 1929 to 1941? Year of Survey Population of Deer 1929 13 1932 29 1935 66 1938 157 1941 398 image 1 because the California false indigo will be able to reproduce faster than it can be consumed by the deer and will be unaffected by the deer population, maintaining its current population image 2 because the increasing number of deer will help spread seeds of the plant and lead to a rise in…The two plant communities on the previous slide are from very different parts of the world but look very similar. Which of the following statements is most likely true? The annual temperatures (but not precipitation) are similar. The annual precipitation (but not temperature) is aimilar Both the annual temperatures and precipitation are aimilar None of the above is likely to be true.The Jena experiment tested the effects of plant species richness on the ecosystem function of various grassland areas over a 15-year timespan. Ecosystem function was determined by measuring the biomass, soil characteristics, types, and numbers of producers and consumers in the area, and tested to determine the strength of the biodiversity effect on the ecosystem. The graphs show the ecosystem function at the onset of the experiment (dotted line) versus the ecosystem function at the end of the 15-year experiment (solid line) in four different test sites (A, B, C, and D).
