- Compare the survival and reproduction strategies of altricial species and precocial species. Although quite different, why are they both successful in maintaining the population of a species? ✓✓✓How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? a.) Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? b.) What is carrying capacity? Do you think carrying capacity applies to people as well as to other organisms? Why or why not?How is a species’ population dynamics affected by the presence of another species with the same niche? Explain
- Using the community assembly theory, provide a framework or explanation on: How do some exotic species outperform locally-adapted native species? Cite specific example(s).Mark Recapture can be written as M N = R Define each term. Use this equation to answer the following question. Show your work. A biologist for Mosaic fertilizer company catches 26 Florida scrub jays as part of their monthly environmental monitoring. Each bird is given a band. The next month, they catch 32 birds. 13 of the birds have bands. What is the estimated population size of the birds in that area?a) Indicate the type of growth and the type of reproductive strategy that each population presents individually.b) Indicate the type of ecological interaction that exists between both populations. Support your answer mathematically.

Which of the following graphs describes the growth of housefly population?How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline?
- How can we determine whether predation is controlling the size of a population? What are the conditions that promote coexistence between predators and prey? please answer bothFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.The competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.
