If most individuals in a population are young, why is the population likely to grow rapidly in the future?a. Death rates will be low.b. The population has a skewed age distribution.c. Immigration and emigration can be ignored.d. Many individuals will begin to reproduce soon.

When individuals in a population are evenly spaced throughout their habitat, their dispersion is termed as .a. clumped;b. uniform;c. random;d. excessive;e. exponential

A population growing exponentially .a. is stable in size;b. adds a fixed number of individuals every generation;c. adds a larger number of individuals in each successive generation;d. will likely expand forever;e. will not crash

Analyzing ecological footprints reveals thata. Earth's carrying capacity would increase if per capita meat consumption increased.b. current demand by industrialized countries for resources is much smaller than the ecological footprint of those countries.c. it is not possible for technological improvements to increase Earth's carrying capacity for humans.d. the ecological footprint of the United States is large because per capita resource use is high.
