This graph shows the sources of the nitrogen entering the Gulf of Mexico as pollution. What is one conclusion you can make based on the information in the graph?
Nitrogen that comes from the atmosphere is more harmful than nitrogen that comes from crops.
Most nitrogen pollution found in the Gulf of Mexico comes from farming crops.
Corn and soybeans are the only crops associated with nitrogen pollution.
Nitrogen is not a problem in the Gulf of Mexico.
The diagram below shows the relationship between some of the organisms in a marine food web. Which of the following is MOST LIKELY to happen if a large number of phytoplankton are killed from runoff entering the ocean?
The number of porpoises would probably stay the same because porpoises are far removed from phytoplankton in the food web
The number of zooplankton would probably increase because they wouldn’t have to compete with phytoplankton for food.
The number of salmon would probably decrease because there would be less food available for zooplankton and herring.
The Sun would probably not emit as much energy because there would not be as many phytoplankton in the ocean.
Which of the following shows the symbiotic relationship between the Rodent and the Bird?
Mutualism
Commensalism
Competition

Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. They typically school under objects such as boats or patches of driftwood for protection from predators. Schooling under these structures also provides yellowfin tuna with easy access to a food source such as smaller herbivorous fish that may be foraging for food around the structures. Which trophic level does yellowfin tuna fill in a food chain?
producer
primary consumer
secondary consumer
tertiary consumer
Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach?
Plants are not infinitely in the world
Producers can only eat what is available
Carnivores are too big to be eaten
Energy is lost when you move up a trophic level

How can a species of mosquito become adapted to having pesticides in their ecosystem?
They have genes that allow it to live, while others die, and they pass along these genes.
They get bigger and can resist the pesticides.
The pesticides with color inside them kills less mosquitoes.
They move quickly and can escape the pesticide.

Observation #1
Observation #2
Observation #3
Observation #4
In a desert habitat, many animals are nocturnal. They sleep in cool dens, caves, or burrows during the day. They hunt for food at night when the temperatures are cooler.
How do desert animals use NON-LIVING elements in their habitats to help them survive?
They are most active at night.
They sleep during the hottest part of the day.
They use dens and caves to stay out of the heat.
They hunt smaller animals that live in the desert.
The picture above shows a highway that was built through a wooded area. Some trees were cut down to create space for the road. The remaining woods line both sides of the highway.

The highway will soon be overgrown by trees as new seedlings sprout in the road.
New animal populations will move to the area increasing the ecosystem diversity.
Animal populations will decrease in size because some individuals are struck by cars.
Animals that live in trees will decrease because they will have to move to a different forest.
