Population Ecology

Population Ecology. Reading: Freeman, Chapter 52. Every species has a geographic range. A geographic range describes where individuals of a species might potentially be located. In the United states, most species have a range of 4-24 states.

EXPONENTIAL GROWTH & DECAY; Application

EXPONENTIAL GROWTH & DECAY; Application. In 2000, the population of Africa was 807 million and by 2011 it had grown to 1052 million. Use the exponential growth model in which t is the number of years after 2000, to find the exponential growth function that models the data . The model is.
