All of the organisms of one species living in the same area.

• Individual

• Population

• Community

• Ecosystem

"Five green and speckled frogs, sitting on a speckled log, eat some most delicious bugs."

Which level of organization is this?

• Individual

• Population

• Community

• Ecosystem

Which of the following is an abiotic factor?

• Grass

• Spider

• Turtle

• Rock

What type of growth is demonstrated in the graph?

• Linear

• Negative

Leveling off of the population after the maximum number the environment can support has been reached.

• Exponential

• Carrying capacity

• Linear

• Negative

Which of the following would likely be a limiting factor to a population?

• Abundance of food

• Living near a water source

• Presence of a natural predator

• Multiple sources for shelter

Which of the following demonstrates population growth when there is limited available water in an area?

• 
• 
• 

Habitat availability increases for a population. How would the carrying capacity of the prey change?

• The carrying capacity would increase as more resources become available.

• Carrying capacity occurs independent of factors in the environment.

• The carrying capacity would decrease as more resources became available.

• The carrying capacity is set in an environment and cannot change.

When Yellowstone National Park was created in the late 1800s, wolves were on the decline. The last wolves in Yellowstone were killed in 1926, but in the 1800s, there were between 100-160 wolves in the park. In 1995, gray wolves were reintroduced to the park.

Which graph (drawn in red) below shows a prediction of how the population would change if there was less water available in the ecosystem?

• 
• 
• 
• There would be no change to carrying capacity.
