The graph shows the percentage of plants pollinated by honey bees in the United States.

How will the decrease in honey bee population affect the ecosystem?

• It will increase the percentage of cotton and orange crops because they are less dependent on honey bees.

• All crop production will remain constant because they will continue to be pollinated by other abiotic and biotic factors.

• 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.

Why is it important to maintain biodiversity among corn crops (genetic diversity) consumed by people?

• The corn will not taste as good to animals if there is greater variety.

• If there are different varieties of corn, then there will also be a variety of other crops on the farm.

• Some corn may be more likely to die from a disease than other types of corn.

• In order to survive, humans must eat a variety of corn not just one kind.

Which step comes after Research in the engineering design process?

• Design

• Build

• Evaluate

• Redesign

What would be a logical justification (good reason) to continue the research of bioplastics?

• They are biodegradable which means they will cause less pollution.

• They are easier to produce than plastic.

• They cost less than plastic.

• They are recycled less easily than plastic.
