What would most likely happen if all the decomposers in an ecosystem were removed?

• The animals in the ecosystem would die because of the spread of disease

• The plants in the ecosystem would eventually die because of a lack of nutrients in the soil

• The plants in the ecosystem would begin to die out because of a decrease in available water

• The animals in the ecosystem would eat other types of food because of a decrease in producers

A food chain in an ecosystem includes blackberry bushes, deer, and wolves. (Deer eat blackberries, wolves eat deer). If the population of wolves decreases, how will this affect the population of blackberry bushes?

• It will decrease because there will be fewer deer

• It will increase because there will be fewer deer

• It will decrease because there will be more deer

• It will increase because there will be more deer.

What would most likely result if all plants in an area were destroyed?

• Consumer populations would increase because more sunlight would reach the ground

• Decomposer populations would increase because more sunlight would reach the ground

• Consumer populations would decrease because plants provide them with water

• Consumer populations would decrease because pants provide them with energy
