5th Grade Science Review 3.10.2025

Using the chart, identify which material Ball A could be made of.

• Copper

• Iron

• Rubber

• Salt

Using the chart, identify which material Powder B could be made of.

• Copper

• Iron

• Salt

• Sand

Identify the material for each ball and each powder using the information in the chart.

• By comparing the labeled properties given in the chart.

• By ignoring the chart and using intuition.

• By testing physical interactions between the items.

• By randomly assigning materials.

Based on the information in the chart, which observations will help Martina identify which object is made from copper?

• The object would not be attracted to a magnet, and it would be orange.

• The object would dissolve in water, and it would be orange.

• The object would not conduct electricity, and it would be black.

• The object would be attracted to a magnet, and it would be black.

What do plants use from the soil to help them grow?

• nutrients

• water

• sunlight

• oxygen

What do animals release into the ecosystem when they breathe out?

• Animals release carbon dioxide into the ecosystem when they breathe out.

• Animals release oxygen into the ecosystem when they breathe out.

• Animals release nitrogen into the ecosystem when they breathe out.

• Animals release methane into the ecosystem when they breathe out.

An organism dying in the ecosystem results in its decomposition and nutrient recycling.

• It decomposes and returns nutrients to the ecosystem.

• It remains intact indefinitely.

• It vanishes completely without a trace.

• It instantaneously reverses its aging process.

Which of the following is a role of decomposers in the ecosystem?

• Produce oxygen

• Break down dead material

• Eat plants

• Hunt animals

Which TWO examples describe the cycling of matter between an organism and the ecosystem?

• An herbivore and an omnivore compete for producers.

• An omnivore eats a producer before it is consumed by a carnivore.

• A decomposer breaks down materials and returns them to the soil.

• A producer uses carbon dioxide from the air to make its own food.

• An herbivore receives energy when it consumes a producer.

What would MOST LIKELY happen if decomposers were removed from the food web shown in the passage?

• There would be more energy available for producers.

• There would be more energy available for consumers.

• Matter would not be recycled back into the ecosystem.

• Matter would be recycled back into the ecosystem faster.
