When storm surge from a hurricane flows into freshwater, which of the following is likely to occur?

• Decrease in salinity and increase of freshwater plants

• Increase in salinity and decrease of freshwater plants

• Decrease in salinity and decrease of freshwater plants

• Increase in salinity and increase of freshwater plants

Which statement about floods is most accurate?

• Floods always have a negative impact on nature and humans

• Floods always impact nature negatively and humans positively

• Floods always have a positive impact on nature and humans

• Floods mostly have a negative impact on humans but can have a positive impact on nature

Which of the following is the best definition of an ecosystem?

• all biotic and abiotic things located in a space no smaller than a forest

• all biotic things located in a particular space

• all the biotic things located in space the size of a forest

• all the biotic and abiotic things located in a particular area

How might animals living on the sea floor be smothered during a hurricane?

• When they cannot adapt to low salinity water

• When they cannot adapt to high salinity water

• When eroded sediments gets deposited on them

• When they are deposited onto eroded sediments

Which of the following statements are correct regarding the impact of fire on a forest ecosystem?

• forest only affect the biotic parts in the forest

• forest only affect the abiotic parts in the forest

• forest only affect the biotic and abiotic parts in the forest

• it has no affect on the biotic and abiotic factors in the forest

Which statement about floods is TRUE?

• floods can destroy plants not tolerant to floods.

• floods always destroy all types of plants in the ecosystem

• floods always take away all nutrients present in the soil

• floods always take away all organic matter from the soil

How does fire help in nutrient recycling in a forest ecosystem?

• organisms leave the fire in search of a new place

• smoke from the fire mixes with the surrounding air

• organic matter gets burned and mixes with the soil

• it is difficult for animals to find food after a forest fire

Why would suppressing fire in a longleaf pine forest lead to a decline in the number of longleaf pines?

• the plants would not be able to produce cones

• absorbing nutrients from the soil would be difficult

• the cones would not open to release seeds

• the animals in the forest would destroy all the longleaf pines

After a hurricane plant A began to do poorly and plant B began to thrive. After several large rainstorms plant A began to thrive and plant B began to do poorly. What hypothesis is best supported by this information?

• Plant A and B do better in high salinity water and soil

• Plant A and B do best in low salinity water and soil

• Plant A do best in low salinity water and soil, Plant B do best in high salinity water and soil

• Plant A do best in high salinity water and soil, Plant B do best in low salinity water and soil
