Population Biology Graphs

Students in a biology class recorded the number of stomata on the top and bottom sides of different plant leaves. The table below shows some of the data collected by one team of students.

The students plan to graph their data. Which of the following would be most appropriate to show the results of their experiment?

• circle graph

• double bar graph

• line graph

• flow chart

On April 20, 2010, an oil rig in the Gulf of Mexico exploded and sank, spilling 210 million gallons of crude oil over a period of 87 days. The graph below shows pelican populations in the Gulf from 1998 to 2018. What does this data suggest about the effect of the oil spill on pelicans?

• The pelican population steadily declined in the years after the spill.

• The pelican population declined and never recovered

• The pelican population seemed to be minimally affected.

• The pelican population declined and then rebounded(went back up).

What happened to the Hare population after the decrease in Lynx population in 1860?

• The decrease of lynx led to an increase in the amount of hares.

• The decrease of lynx led to a decrease in the hare population.

• The hare population stayed the same.

According to the graph, what scenario best fits?

• The Owl Population increased because there were more mice to eat.

• The Mice population increased because Owl population decrease, so there were less owls hunting mice.

Which scenarios best applies to the above graph?

• The fox population increased because they did not reach their Carrying capacity.

• The rabbit population stayed the same because there were producing more rabbits then were being hunted.

• The fox population increase because there are plenty of rabbits to eat.

• The fox population decreased, while the rabbit population increased.

How did the increased population of wolves in year 5 affect the deer population in year 6?

• The increase in wolves led to a decrease in deer.

• There was no effect because the data showed that the population stayed the same.

• The increase in wolves led to an increase in deer.

In a population biology graph, what does the carrying capacity represent?

• The maximum number of individuals an environment can support

• The initial population size

• The rate of population growth

• The time it takes for a population to double

What does a steep slope in a population growth graph indicate?

• Slow population growth

• Rapid population growth

• Stable population size

• Declining population size
