Question
Chapter 27, Problem 3FIB
Summary Introduction
Introduction:
The changes in a population number could be due to birth rate, death rate, immigration, and emigration. A wide gap between the birth and death rate could lead to faster growth in rate of population. Death and emigration lead to decrease individuals from a population and birth and immigration lead to adding individuals in a population.

- Where is the growth rate the fastest on a logistic growth curve? at the inflection point in the very beginning when the population is small right before it reaches the carrying capacityarrow_forwardWhen per capita growth rate (r) is a positive number, the population size is: a decreasing if it is under 1, increasing if it is over 1 b decreasing c stable (doesn't increase or decrease) d increasingarrow_forwardThe maximum sustainable yield (MSY) is the highest rate at which a potentially renewable resource can be used indefinitely without reducing its available supply. The idea is to remove individuals while keeping the population at a constant growth rate and size, but to find the size where the harvest is maximized. The greater the growth rate, the more individuals you can remove and not change the population size. Where is the growth rate at its maximum? To find this look at your logistic model simulator. 1. Set up a hypothetical salmon population where the carrying capacity is 20,000 fish, the maximumr is 0.7. According the the maximum sustainable yield (MSY), at what population size should we maintain the salmon while fishing?arrow_forward

Select "yes" or "no" for each. logistic [ Choose ] exponential [ Choose ] cycling [ Choose ]arrow_forward
- Read and highlight ways limiting factors affect the population growth Examples of how limiting factors affect population growth Abiotic (nonliving) limiting factors include things like wildfire, hurricanes, pollutants, droughts, floods and seasonal climate extremes. These factors limit all populations in a given area regardless of the size of the population. For example, a wildfire that sweeps through a dense forest in the Everglades has a big impact on every population in the ecosystem, regardless of how big the population is. Limiting factors can also be biotic-having to do with living organisms. Competition and predation are examples of biotic living factors. Organisms compete for available resources like food, water, and shelter. If the resources are plentiful then the populations can increase because there is less competition. If the resources are decreased in an area, competition increases and population size decreases. For example Mountain chickadees (Parus gambeli) compete for…arrow_forwardWhat is the relationship between population density and available resources? exponentially proportional There is no relationship. directly proportional inversely proportionalarrow_forwardIn the logistic model of population growth, per capita growth rates are highest at __ densities and population growth rates are highest at ___ density (NOTE: assume ‘high’ refers to at or near K).
