Relationship between Population and Body Mass in Australian Mammals 3.0- Quoll Bandicoot Wombat • Rat-kangaroo x Potoroo o Possom species O Tree kangaroo A Wallaby o Kangaroo Bear cuscus x Glider species 2.0- 1.0- A 0.0- 0.0 1.0 2.0 3.0 4.0 5.0 Log mass (grams) Figure 19.2 Australian mammals show a typical inverse relationship between population density and body size. As this graph shows, population density typically decreases with increasing body size. Why do you think this is the case? Log density (km)

Which of the following correctly explain the pattern of human population growth up to now.   Question 23 options:   Human population grew slowly for most of history.  The population rose exponentially for about 200 years and then in the last decade population growth has stopped.   Human population grow exponentially for most of history.  Recently it is experiencing logistic growth.   Human population grew slowly for most of history.  In recent centuries it has go through exponential growth.   Human population grew slowly for most of history.  In recent centuries it has go through logistic growth.

The graphs below show the size of three populations over time. Which population is NOT currently being affected by the carrying capacity of its environment? B O Population A O Population B O Population C

Which of the following statements about exponential growth is FALSE? O a. Increases in the size of the population do not affect per capita rate of increase (r). Ca. b. Exponential growth adds a constant number of individuals per unit time to a population as N gets larger. C. In reality, it is not possible for exponential population growth to continue indefinitely. d. In an exponentially growing population, the % increase of the population per unit * time doesn't depend on the number of individuals (N) in the population.

Can you answer the following questions please in the picture below

When the conditions are favorable for a population at low density, such as when a species colonizes a new environment, population growth is typically O logistic. exponential. tangential. dynamic.

Which of the following is a density-independent factor limiting population growth in humans?     fatal genetic diseases     temperature     competition for food     fatal contagious diseases

A population bottleneck will typically result in; A larger, more diverse population A smaller, less diverse population A larger, less diverse population A smaller, more diverse population

Populous nations such as China have instituted strict policies tocurb population growth. In 1979, China implemented a “one-child”policy.Do you think that such strict control methods are appropriatefor population control?

You have been put in charge of managing a population of the endangered pink fairy armadillo. The population is currently 500 (N=500). What kinds of information would need to have to determine how big the population will be in 10 years? What environmental influences might influence the accuracy of your prediction?
