- INTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F. Gause, The Struggle for Existence (Williams and Wilkins, Baltimore, 1934). Figure 54-5 G.F. Gauses classic experiment on interspecific competitionBiology Question! Water wisteria is an aquatic plant that is easy to care for and reproduces very quickly. A small man-made pond of 350 L contains 78 water wisteria plants. 15 new plants are introduced daily to the pond, while 50 plants are taken out once a week to be sold at local pet shops. What is the overall population change in a two-week period? Express your answer rounded to the nearest whole number. What is the population density of water wisteria at the beginning? Express your answer as a value between 0 and 1 rounded to two decimal places.In January 2010, a population of organisms had a size of 564. By the end of the year 109 of those individuals had died, but 384 were born. what is the net reproduction per capita for this population?

Question 7 options: when individuals of one species inhibit individuals of another by consuming a shared resource situations where the occupancy by one individual precludes the establishment of others when one organism grows over another, thereby inhibiting access to some essential resource when chemical growth inhibitors inhibit germination and establishment of other species when nonterritorial meetings between individuals negatively affect one or both of the participant speciesDirection: read each situation in the table below then state if it is a density independent limiting factor or a density dependent limiting Factor. Indicate the specific limiting factor that is occurring (i.e, immigration, predation, and diseases and parasites)

- In this lesson, we explore population momentum (the time lag between a change in birth/death rates and theslowing of population growth). In Step 1, we explore the effect of changing the age of reproduction, usingNigeria as an example. You will consider the human and ecological impacts of unchecked population growth aswell as the human cost of China’s successful attempt to curb its own growth answer questionsMatch each organism to the most likely life strategy and growth type Organism Life Strategy K-Selected or r-Selected Growth Pattern Logistic or exponential Beavers are monogamous mammals that breed annually and produce a litter of about one to four kits. Kits remain in the care of the colony until two to three years of age. Century plants are flowering plants native to Mexico. Century plants live 10-30 years and flower only once in their lifetime and perish shortly after. THeir giant flowering stalks can reach up to 9m long but they reproduce primarily via suckers. Honeybees live in colonies as large as 50,000 bees. Only the queen lays eggs and lays up to 2,000 per day. The house mouse is a polygamous mammal with the gestation period of about 20 days and a litter size of up to 14. Mice nurse their young until about 20 days.Converting a prairie to a farm field is an example of.__________ overharvesting habitat loss exotic species climate change
