2-4 (11C)A student sets up a compost bin outdoors. Inside the bin microorganisms convert the student’s vegetable and paper scraps into rich fertilizer. Which of the following best describes the role that these microorganisms play in natural habitats?A The microorganisms help balance the numbers of producers and consumers.B The microorganisms help keep nutrients cycling through the ecosystem.C The microorganisms turn solar energy into sugars.D The microorganisms function as autotrophs.2-5 (12C)According to this food web, which of the following are omnivores?

A SnakesB RabbitsC MiceD Grasshoppers2-6 (12A)Bacteria are present in the digestive tract of some herbivores. The bacteria break down plant cellulose, making it possible for the herbivore to digest plant material. These bacteria live in a stable environment with sufficient food and water. The herbivore and the bacteria in this relationship –A benefit each otherB compete for survivalC are producersD are secondary consumers
