Fly Population 4. The graph below represents the growth of a population of flies in a jar. Which letter(s) indicates the part of the graph where biotic potential is the only thing affecting the population? Choose all letters that apply. B Days 5. A population of mice has grown so rapidly that there are 2,400 individuals in an ecosystem that will support about 1,800 mice. The mouse population is most likely to A. undergo a decline in size, possibly to a stable level at or below 1,800 individuals B. have no effect on the population size of predators that feed on mice C. continue to have a birth rate that equals the death rate D. continue to increase 6. A population will always grow exponentially A. if it is limited only by density dependent factors. B. if there are no limiting factors C. if it shows logistical growth

ENDANGERED ANIMAL is CA least tern bird 1-2 bases on the CA least tern bird Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?
16- A population's carrying capacity ____. a- increases as per capita growth rate (r) decreases b- decreases as per capita growth rate (r) decreases c- can never be exceeded d- may change as environmental conditions change 17- According to the logistic growth equation ________. a- the instantaneous per capita growth rate (rinst) increases as N approaches K. b- population growth is zero when N equals K. c- the population grows exponentially when K is small. d- population growth is maximized when N equals K.
Wolves Elk Willow 4. The top two graphs show how the population of wolves and the population of elk changed following the introduction of wolves into Yellowstone National Park. The third graph shows trends in the amount of growth of willows (data for annual growth ring size from two different studies). Fill in the table below for each organism: State whether population size or amount of growth generally decreased, increased, or stayed the same. Explain a likely reason for each trend. Use the information from the food web to understand the trends in elk population and willow growth. If an increase in a predator population results in a decrease in an herbivore population which in turn results in an increase in plant growth, this type of effect is called a trophic cascade. cb amalg nodiso Trend in population size or amount of growth Population Population (Thousands) 120 100 80 Ring area (mm2) 60 40 20 O 20 15 10 $ 20 15 10- 5 0 A Wolves B Elk F Willow 1990 1995 201508 2000 Year NEE)…

Biology 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.

3. In 1940 there were 12 whooping cranes in the population. In 1945, five years after hunting whooping cranes was made illegal, ecologists calculated the whooping crane population growth rate (X) at 1.2 and estimated the population size to be 30 individuals. Using the population growth rate calculated from 1940-1945, what would be the estimated population size for whooping cranes 20 years into the future (1965)?
