The image shows a goby fish and a snapping shrimp that live together in a burrow. The shrimp digs and cleans the burrow. Outside of the burrow, the shrimp is almost blind and keeps its antennae on the goby fish. When the goby fish spots predators, it quickly moves into the burrow, and the shrimp follows. What can be concluded from this relationship between the goby fish and shrimp?

• Both species benefit from the activity of the other.

• Both species compete for the same living space.

• Only the fish is harmed from the relationship due to the shrimp’s enlarged snapping claw.

• Only the shrimp benefits from the relationship as it is warned about predators.

Aphids are insects that feed on plant sap, causing growth to slow, leaves to wilt, and in some cases, the death of the plant. Ladybugs, which also live on plants, feed on aphids. What is the type of relationship between ladybugs and plants?

• competition

• mutualism

• parasitism

• predation

Which relationship represents an example of mutualism?

The graph shows the percentage of crops pollinated by honey bees in the United States. It has been estimated that more than 10 million beehives were lost in 2013 in the United States due to colony collapse disorder caused by the widespread use of pesticides. How will the decrease in the honey bee population affect the ecosystem?

• It will increase the percentages of almond and apple crops because insects other than honey bees will help pollinate these crops.

• It will increase the percentages of cotton and orange crops because these are less dependent on honey bee pollination.

• It will decrease the percentages of almond and apple crops because lesser numbers of honey bees are available for pollination.

• It will decrease the percentages of cotton and orange crops because the populations of other insects will also decline along with honey bees.

A student divides a garden into three sections to determine under which conditions bean plants grow best. The student ensures that each section of the garden receives the same amount of sunlight but varies the number of seeds planted in each section. The student records how many seeds germinated after two weeks. According to the student’s observations, what can most likely be concluded about Section 1 of the garden?

• There is not enough sunlight for all of the seeds to germinate.

• There is not enough space for all of the seeds to germinate.

• There is not enough carbon dioxide for all of the seeds to germinate.

• 
  There is not enough water for all of the seeds to germinate.
