APPLY YOUR KNOWLEDGE Human populations are subiect to the same population control factors in the environment that mipact natural populations. For example, during the 14th century, the bubonic plague killed approximately one- third of the human population. A. Is the bubonic plague an example of a dènsity-dependent or density-independent factor? Explain. B. Two-thirds of the population survived the bubonic plague, even though many of the survivors were most likely bitten by disease-carrying fleas. In terms of evolution, explain how it was possible to be a survivor. C. Discuss two ways that humans have increased the carrying capacity of their population.
Organismsthat produce many offspring would best be characterized by which of thefollowing?a.A convex survivorship curveb.A concave survivorship curvec.A linear survivorship curved.A sigmoidal survivorship curvee.None of the choices apply
Graph Analysis - Predator-Prey Graph Isle Royale National Park on a remote island was established in 1940, and designated a wilderness area in 1976. The only mode of transportation available is by boat or seaplane. Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Disease has also influenced the wolf population. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus.
