What is the difference between exponential and logistic growth? Which type do most populations exhibit?
Answer - Exponential growth is seen when a population per capita growth rate stays the same regardless of the size of the population. It is represented by a J-shaped curve.
Logistic growth is seen when a population per capita growth rate decreases as population size approach the maximum which is imposed by limited resources. It is represented by an S-shaped curve.
Most population exhibit logistic growth because most population carrying capacity fluctuates.
What is the difference between exponential and logistic growth? Which type do most populations exhibit?
Describe the differences between logistic and exponential growth? When would you expect populations to have one or the other? Describe what the variable K represents in the logistic growth equation, and describe a scenario for how you might get an increase in the variable K. Response must be 2-3 paragraphs.
answer both questions please Which of the following is true regarding the comparison between growth of bacterial populations and growth of single-celled eukaryote populations? Bacteria typically grow more slowly than eukaryotes, leading to lower population growth. Bacteria typically grow more quickly than eukaryotes, as eukaryotes have more complex cell structures and components, which leads to slower population growth of eukaryotes. Doubling times in eukaryotic cells are difficult to estimate because they grow so quickly. Bacteria species typically exhibit exponential population...
10 marks Essay Write your answers on separate pages. l. Many populations exhibit the following growth curve: Phase A--T← Phase B Time (a) Describe what is occurring in the population during phase A (break it up into three sections as you explain the change in slope). (b) Discuss THREE factors that might cause the fluctuations shown in phase B nisms demonstrate exponential (r) or logistic (K) reproductive strategies. Explain these two strategies and discuss how they affect population size over...
Khan Academy Question 42 2 pts Which of the following causes populations to shift most quickly from an exponential to a logistic population growth? decreased death rate favorable climatic conditions competition for resources O removal of predators Question 43 2 pts Which of the following relationships is detrimental to both species involved? O commensalism O competition O mutualism O parasitism
14. What is the difference between generation time and the rate of population growth? 15. When using the logistic population growth model, what are the different causes of slow population growth at low population sizes versus high population sizes? 8. What are the patterns of survival with age in the three types of survivorship curves? 9. How would you describe the generation time of a population? 10. Given that white tailed deer give birth to fawns each spring, which population...
What is the difference between growth DISTANCE charts and growth VELOCITY charts? What do they each measure? What are some key differences between the charts (units on y-axis, at what ages is the highest point on the charts, or the lowest points, and what are their values, where are there increasing or decreasing slopes) and what do they tell us about growth?
Under logistic growth for a population whose carrying capacity is 100, at what population size would you expect the greatest realized per capita growth rate? N-0 Whatever populations made NEK N-1/2
What do the K represent in the logistic growth mode formulasl? M= Carrying Capacity DelatP = kP(1-P/M) - Growth k(1-P/M)- Growth Rate
what is the difference between experimental research and correlational research and which research type do you think would have more accurate results or is better?
5. Consider the system: dz 4y 1 dy (a) Are these species predator-prey or competing? b) What type of growth does species z exhibit in absence of species y?
