Below is a model of a pond ecosystem that a group of fourth graders are analyzing. Which of the following best describes the role of the mosquito?

• The mosquito is a consumer because it consumes other insects to live.

• The mosquito is a consumer because it eats dead materials.

• The mosquito is a producer because it makes its own food.

• The mosquito is a decomposer because it eats insects.

Below is a model of an ocean ecosystem that a group of fourth graders are analyzing. The student claims that only consumers are shown in the community. Which of the following pieces of evidence would support this claim?

• There is a living organism in the model that breaks down dead materials.

• There is a living organism in the model that is a predator and eats its prey.

• There is a living organism in the model that makes its own food.

• There is a living organism in the model that grows to be very large.

A team of fourth grade students were tasked with developing a model to describe the roles of animals in a community. The students created the following model of a mangrove near the ocean. Using the model, which of the following best describe the role of the heron?

• The heron is a consumer because it eats small fish.

• The heron is a producer since it makes its own food.

• The heron is a decomposer because it eats the crabs.

A student made the following chart to describe the roles of animals in a forest ecosystem. Another classmate reviewed the chart. Which of the following BEST illustrates the feedback the student should give?

• The description for a consumer needs to change to eat another living animal. They do not eat plants. Therefore, the rabbit is not a consumer.

• The description for producers and decomposers should be swapped. A producer makes its own food and a decomposer breaks down dead material.

• The description for a decomposer needs to change to make its own food after breaking down dead material. An example of a decomposer is a hawk.

• The description for consumer and decomposers should be swapped. A consumer makes its own food and a decomposer eats another living thing.

A student claims that only consumers are labeled and part of the ecosystem since consumers require food to survive. Which of the following BEST describes whether the student's claim is correct or incorrect?

• c. The decomposer eats the secondary consumer, which is then eaten by the producer.

• d. The decomposer is where energy is created.
