- Which of the following can explain why species are able to coexist, even if the competitive exclusion principle is generally true? a) Species may be competitively equivalent, with the outcome of each competitive encounter being essentially random. b) Competitive exclusion may take many generations; prior to that point, there will be coexistence. c) Spatial heterogeneity in the distribution and concentrations of limiting resources can result in variation in the strength of competition across the landscape. choose all the answers that apply.arrow_forwardConsider the following graph depicting the population growth of bacteria in an “ideal” laboratory created condition. Explain what conditions would allow for a population to grow exponentially like in this example, and why this is unlikely to occur naturally in the wild. ✓✓ Population (number of bacteria) 35000 30000 25000 20000 15000 10000 5000 0 Population Growth of Bacteria in Ideal Conditions 2 Time (hours) 3arrow_forwardI think my reasoning is wrong because I keep getting Italy as the answer choice. It seems odd to me that I got Italy three times. The other option is Burkina Faso. So, it is either Italy or Burkina Faso. Please carefully review my answer choices because I could be WRONG. Richness refers to the total number of species of microbe in the gut microbe. Italy, Europe seems to have greater gut microbe richness. Diversity- It is the variety of species Italy has a greater variety of species. Evenness refers to the distribution of abundance across the species in the community. Italy seems to have greater evenness as the species percentage is almost similar.arrow_forward
- Colony collapse disorder (CCD) is unexplained loss of entire bee colonies that has been occurring in increased numbers across the world. The cause of the disorder is unknown, although it has been suggested that pesticides may play a role. To study this phenomenon, 300 bee colonies at 20 different sites across the U.S. are analyzed. Colonies are classified as having no CCD symptoms (group 1) or as having CCD symptoms (group 2). Bee pollen is isolated from group 1 and group 2 colonies and analyzed for the presence of pesticides. Significantly higher average pesticide levels being found in group 2 colonies, the conclusion of the study states that increasing pesticides use may be leading to the death of bees and a loss of bee colonies in CCD. Does this study have a control group? If so, what is the control group? If not, why not?arrow_forwardBiologically, what conditions are necessary for stable coexistence of competitors?

- Describe and give (an example) the following relationships between organisms. a) predation b) parasitism c) mutualismarrow_forwardA mutation occurs in a single bacterium that causes it to produce a new enzyme. This enzyme helps the bacterium process nutrients more efficiently, increasing the bacterium's odds of survival. Every 30 minutes, the bacteria in the colony divide, passing their genes on to their offspring. Some bacteria survive, while others do not. Because resources are limited, the colony has a steady population of 114 bacteria. The bacterial colony is shown below at three different time intervals. Assume that the survival trend shown in the diagram continues. At 3.0 hours, the mutant bacteria will make up how many percent of the entire colony?arrow_forwardBacteria reproduce by fission (splitting in two) and can respond very rapidly to environmental changes. A culture of bacteria is found to contain 4.95 X 109 bacteria and the carrying capacity of the culture is 5.0 X 109. How will the bacterial population change in the near future. Group of answer choices -it will increase very rapidly to K -it will increase very slowly to K -it will grow exponentiall -it will decrease very rapidly to Karrow_forward
- Can you help me giving an example and a hypothesis about this questionarrow_forwardYou place two species of bacteria in a 50%/50% ratio into a test tube with nutrients that favor the growth of both bacterial species. After two days the ratio is 80%/20%. Assuming that the bacteria do not attack each other, do you think this is an example of competition?arrow_forward80 i Fig. 1 75 h 70 g 65 60 e 55 d 50 45 b 40 a (C) Temperature 20 22 24 26 28 30 32 34 36 38 40 Questions 1-25 are based on the story of Frog and Toad. The figure above (Fig. 1) is a 2-dimensional representation of a space for frog (in the absence of a competing species) based on the combination of two variables: moisture (% Relative Humidity [RH]) and temperature (°C). Size of the frog icon corresponds to how well it does (in terms of ecologic fitness) at various positions along these two environmental gradients. Flattened frogs indicate dead frogs; environmental conditions which are unsuitable for the frog's survival and reproduction. Italicized letters and numbers (on top) represent coordinates. Unitalicized numbers adjacent to the arrows represent values for either RH (the vertical arrow) or temperature (the horizontal arrow) 1. Fill in the blank а. Fundamental niche b. Habitat с.
