Whаles аnd fооd chаins: Figure 8.13 frоm Chapter 08 shows a marine food chain with 7 trophic levels. Caption: A simple food chain. Phytoplankton are eaten by herbivorous zooplankton, which are eaten by carnivorous zooplankton, which are eaten by small fishes, which are eaten by large fishes, which are eaten by seals, which are eaten by killer whales. Each step in this chain is one trophic level higher. For this question, refer to the first paragraph in Section 9.3.3 Marine Mammals which briefly describes several whale species. (Note: Killer whales are also known as orcas.) a) Which whale species in this paragraph is at the top of the shortest food chain, i.e., the one with the fewest trophic levels? What are the 3 levels in this food chain? You may use general terms as in the figure caption above, e.g., "phytoplankton". b) Which whale species is at the top of an intermediate-length food chain? What 4 levels in that food chain can you identify? c) Which whale species in this paragraph is at the top of the longest food chain? What 5 (or more) levels in that food chain can you identify?

Binаry Seаrch Cоmplexity Anаlysis Fоr the fоllowing binary search algorithm, analyze and determine the following complexity using Big O notation. Justify your answer. Time Complexity Auxiliary Space // Java implementation of recursive Binary Search class BinarySearch { // Returns index of x if it is present in arr[l.. // r], else return -1 int binarySearch(int arr[], int l, int r, int x) { if (r >= l) { int mid = l + (r - l) / 2; // If the element is present at the // middle itself if (arr[mid] == x) return mid; // If element is smaller than mid, then // it can only be present in left subarray if (arr[mid] > x) return binarySearch(arr, l, mid - 1, x); // Else the element can only be present // in right subarray return binarySearch(arr, mid + 1, r, x); } // We reach here when element is not present // in array return -1; }
