26. Give an example scenario of comeptition

27. A zebra and giraffe must compete to drink the same water from a watering hole in the African Savanna 

28. What is the carrying capacity of this graph?

29. 1,000 organisms 

30. If the prey increases, what will happen to the population of the predator?

31. The population of the predator species will also increase

32. True or False: Limiting factors can sometime be beneficial to an environment? Please explain your answer.

33. True. Limiting factors allow for population of species to be below the carrying capacity. 

34. What limiting factor reduces the population of rabbits in the winter, but not the spring?

35. Cold weather or decline in natural resources such as food source. 

36. What would happen to an ecosystem if the population of mosquitos declined rapidly?  Mosquitos are primary consumers.  

37. The producers would increase, predators would decrease
