EOG Science Review

What would most likely happen if all of 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.

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 plants provide them with energy.

Predict how a change in one part of an ecosystem can affect the entire system.

• A change in one part of an ecosystem will have no effect on the rest

• A change in one part can lead to a chain reaction affecting the whole system

• A change in one part will only affect that specific part

• A change in one part will improve the entire ecosystem
