Which of the following species is most likely to have a Type III survivorship curve?a. humans, Homo sapiensb. common lizards, Zootoca viviparac. thale cress plants, Arabidopsis thalianad. lynx cats, Lynx canadensis

To figure out the human population density of your community, you would need to know the number of people living there anda. the land area in which they live.b. the birth rate of the population.c. the dispersion pattern of the population.d. the carrying capacity.

Why is there a trade-off between survivorship and fecundity?

Based on current growth rates, Earth's human population in 2019 will be closest toa. 2.5 million.b. 4.5 billion.c. 7.5 billion.d. 10.5 billion.

The term (K−N)/Ka. is the carrying capacity for a population.b. is greatest when K is very large.c. is zero when population size equals carrying capacity.d. increases in value as N approaches K.

According to the graph shown here, the carrying capacity for fruit flies in the environment of the culture bottle is .a. 0 flies;b. 100 flies;c. 150 flies;d. between 100 and 150 flies;e. impossible to determine

The observation that members of a population are uniformly distributed suggests thata. resources are distributed unevenly.b. the members of the population are competing for access to a resource.c.the members of the population are neither attracted to nor repelled by one another.d. the density of the population is low.

With regard to its rate of growth, a population that is growing logisticallya. grows fastest when density is lowest.b. has a high intrinsic rate of increase.c. grows fastest at an intermediate population density.d. grows fastest as it approaches carrying capacity.

Pose a hypothesis to explain why the human population has undergone especially rapid growth over the past 200 years. Describe two examples of density-dependent factors that limit human population growth. Is it possible that humans have surpassed Earth's carrying capacity?
