question
Which kind of organism is a heterotroph?A.) PhotosynthesizersB.) ProducersC.) ConsumersD.) Plants
answer
C.) Consumers
question

answer
A.)They recycle nutrients into the ecosystem.
question
A diagram illustrates that grass is eaten by insects, birds, and mice. The insects are eaten by hawks, snakes, and toads. The birds and mice are eaten by foxes, hawks, and snakes. The toad is also eaten by the snake. Which best describes the diagram? A.) PyramidB.) Food chain gridC.) Food webD.) Trophic level
answer
C.) Food web
question
What might happen to the food web below if the number of phytoplankton drastically decreased?A.) The small fish and wading birds would be affected.B.) Only the small fish would be affected.C.) The small fish, bivalves, and invertebrates would be affected.D.)The entire food web would be affected.
answer
D.)The entire food web would be affected.
question
What is shown in the image below?A.) Food chainB.) Trophic chainC.) Food webD.) Energy web
answer
C.) Food web
question
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?A.) ProducerB.) Primary consumerC.) Secondary consumerD.) Tertiary consumer
answer
C.) Secondary consumer
question
Energy flows from the producer level to the ________________ level.
answer
Consumer
question
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?A.) Plants are not infinite in number.B.) Producers are limited by consumers.C.) Carnivores are too large to be eaten.D.)Energy is lost at each trophic level.
answer
D.) Energy is lost at each trophic level.
question
Maggots feed on dead and decaying organisms for energy. What are maggots?A.) AutotrophsB.) ProducersC.) DecomposersD.) Heterotrophs
answer
C.) Decomposers
question
Which organism is an example of a producer?A.) MothB.) MushroomC.) RoseD.) Cheetah
answer
C.) Rose
