This is a food chain that includes grass, a grasshopper, and a bird.

grass → grasshopper → bird

How is the grass in this food chain best described?

• It is a producer, because it makes its own food.

• It is a producer, because it is eaten by consumers.

• It is a consumer, because it gets energy from producers.

• It is a decomposer, because it breaks down sunlight.

Which would most likely cause a decrease in a population of herbivores?

• an increase in the number of producers

• a decrease in the types of decomposers

• an increase in the types of plants

• an increase in the number of carnivores

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.

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 of predators.

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.
