Ecology Unit Review

If you were to graph the data in the table, it would show:

• An increase in population over time

• a decrease in the population over time

• the population staying the same over time

• an increase in population at first, followed by a decrease over time

What might be causing the pattern in these data?

• the population's food resources became less abundant

• the population's predators became less abundant

• the population's habitat became less abundant

• the population's competitors became more abundant

• it will increase

• it will decrease

• it will stay the same

• it will first increase, then decrease

A new species of fish has been introduced into Twin Lakes. This fish eats minnows, a smaller fish that already live in the lake. The introduction of this new species of fish into Twin Lakes provides an example of:

• competition

• parasitism

• predation

• mutualism

An ecologist used the transect method to investigate a forest. They ran a transect line from the edge of the forest towards the interior of the forest. The data they collected in the six quadrats spaced 20 m apart are as follows: What pattern do you see in the number of native birds?

• The number of native birds increases from the interior to the edge of the forest.

• The number of native birds increases from the edge to the interior of the forest.

• The number of native birds shows no pattern.

• No pattern can be detected because there were no birds towards the edge of the forest.

An ecologist used the transect method to investigate a forest. They ran a transect line from the edge of the forest towards the interior of the forest. The data they collected in the six quadrats spaced 20 m apart are as follows: ^{What pattern do you see in the plants along the transect from the edge to the interior?}

• The number of native plants increases while the number of non-native plants decreases.

• The number of native plants remains the same while the number of non-native plants increases.

• The number of native plants increases while the number of non-native plants remains the same.

• The number of native plants and non-native plants both increase.

An ecologist used the transect method to investigate a forest. They ran a transect line from the edge of the forest towards the interior of the forest. The data they collected in the six quadrats spaced 20 m apart are as follows:

^{What might be causing the above patterns?}

• Both native plants and birds prefer lower temperatures.

• Non-native plants prefer higher temperatures.

• Both native plants and non-native plants prefer lower temperatures

• Native birds prefer non-native plants.
