# Survivorship CurvesExamine the survivorship curve graph below, which will assist in answering questions about different life strategies of organisms.## Graph Explanation:The graph displays three types of survivorship curves, labeled A, B, and C. These curves depict the percentage of survivors (on a logarithmic scale) over the percentage of maximum life span.- **Curve A**: Represents organisms with high survivorship through early and middle life, followed by a rapid decline in the number of individuals surviving into late life (e.g., humans and other large mammals).- **Curve B**: Illustrates a constant death rate/survivorship rate over the organism's life span (e.g., birds).- **Curve C**: Indicates low survivorship for the very young with survivorship improving as individuals age and pass the juvenile period (e.g., marine invertebrates, trees).## Questions to Consider:**19. Which curve would fit an organism that cares for its young and reproduces relatively late in life?**This question involves selecting the curve that best represents species with a high degree of parental care and delayed reproduction.**20. The vast majority of acorns produced by an oak tree never germinate or die during their first year of growth. If they survive past the first year, however, they are likely to live the maximum life span. Which survivorship curve does this represent?**This question requires identifying the curve indicative of organisms producing many offspring with high initial mortality but improved survivorship after an initial critical period.

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.

Q- You are studying the growth of a particular species of plant and you notice that as time passes, your plants’ root: shoot ratios consistently decrease. In this system, is the limiting resource an above-ground resource, or a below-ground (soil) resource? A- Above ground; because the plants are allocating more resources to root growth B- Above ground; because the plants are allocating more resources to shoot growth C- Below ground; because the plants are allocating more resources to root growth D- Below ground; because the plants are allocating more resources to shoot growth

Question:- Franco and Nobel (1989) discovered that there are downsides to having a nurse plant for young cacti. They found that while young cacti survive more often, they grow slower than young cacti without a nurse plant. What are the authors' two explanations for why that happens?
