I need help with five multiple choice marine science questions.
1)When severe weather damages the plant life in an ecosystem, what effects might this have on other organisms in the same ecosystem?
a)- Other organisms could starve or have to leave the area if they depend on the plants as food.
b) -Other organisms could change their behavior to take the place of the plants in the ecosystem.
c )-Other organisms would not be affected.
d )-Other organisms could replace the plant energy with radiant energy from the sun.
2)As the climate changes, the average ocean temperature is rising. Using this information, predict what will most likely happen to El Niño events in the future.
a)-El Niño events will intensify because they rely on warmer water sinking to the seafloor.
b)-El Niño events will intensify because they will build on the already warm waters at the equator.
c)-Some El Niño events will be stronger, but most will be weaker because the ocean currents are unpredictable.
d)-El Niño events will become more similar to La Niña events and establish a new weather pattern.
3)Which of the following examples is the most likely way severe weather can negatively affect the biodiversity of a marine ecosystem?
a)-A severe thunderstorm brings rain and wind to an intertidal zone.
b)-A storm surge from a hurricane floods a coastal area.
c)-A tornado causes a waterspout.
d)-A blizzard adds snow and ice to an arctic glacier.
4)El Niño events are characterized by warmer than normal ocean temperatures near the equator in the Pacific Ocean. Which weather events are most likely to occur as a result?
a)- Increased rainfall across the eastern Pacific Ocean
b)-Decreased flooding across the eastern Pacific Ocean
c)-Drought along the South American Pacific coastline
d)-Colder winter along the South American Pacific coastline
5)According to the Severe Weather Activity worksheet, El Niño events most likely occurred during which of the following years?
a)-2006 and 2015
b)-1997, 2006, and 2015
c)-1997 and 2015
d)-1997 and 2006
