In your Answer Document, identify two nonliving resources the organism needs to live.

Explain how the organism uses each of the two nonliving resources. (2 points)

Question 11

Planaria are flatworms that are found in shallow streams, often attached to the bottoms of rocks. A class is studying a population of planaria in a nearby shallow stream. The graph below shows data collected over 11 weeks.

[pic]

The population started to decrease after 5 weeks. The students concluded that the stream did not have enough food to support a large population of planaria.

[pic]B. 500

[pic]C. 400

[pic]D. 300

Question 12

Termites eat wood but cannot digest it. Protozoans live in the termites’ stomachs and use enzymes to break down the wood. The digested wood provides nutrition for both the termites and the protozoans.

What type of relationship is this?

[pic]A. mutualism

[pic]B. parasitism

[pic]C. predation

[pic]D. commensalism

Question 13

Two students are studying the effect of insects on plant growth. They prevent insects from eating some plants by covering the plants with a transparent mesh cloth. The students leave the other plants uncovered. Both students use the same pots and the same type of soil for each plant. The table shows details of their investigations.

[pic]

Which statement describes a weakness in the investigations?

[pic]A. Student X used an equal number of plants.

[pic]B. Student X exposed the plants to varying sunlight.

[pic]C. Student Y covered half the plants with mesh cloth.

[pic]D. Student Y potted the plants in the same type of soil.

Question 14

The food web shows the interactions between organisms in a meadow ecosystem.

[pic]

Which organism gets food energy directly from both plants and animals?

[pic]A. fox

[pic]B. grass

[pic]C. grasshopper

[pic]D. snake

Question 15

An eighth-grade class wants to identify a representative sample of the crawling and flying insects living in the schoolyard. The students build and set five traps like the one shown below. They place the traps in the listed locations at the end of the school day and check them the following morning to see what they have caught.

[pic]

Two variables in this investigation are location of trap and size of jar.

In your Answer Document, explain how each of these variables could affect the conclusions of the investigation.

Explain why the students’ collecting procedures will not allow them to collect representatives of all insects living in the schoolyard.

Question 16

Use the diagram and information below to answer question #.

A teacher places a ribbon of magnesium on a wire and suspends it in a flask. She then seals the flask and runs electricity through the wire to ignite the magnesium. After the magnesium is completely burned, a student notices a white powder in the bottom of the flask. The mass of the flask system (the flask and its contents) is determined before and after the magnesium is ignited.

Question 17

A tightly sealed glass box has a mass of 20,000 grams and contains a 5-gram cube of ice, making the total mass 20,005 grams. The box with the ice is placed in direct sunlight. After three hours, the box appears to be empty, with just small droplets along the sides of the box.

Which statement describes the mass of the sealed box after sitting in the sun?

[pic]A. The mass decreases because the ice melted into a liquid.

[pic]B. The mass remains the same as the ice melts and then evaporates.

[pic]C. The mass increases as the gases inside the box absorb energy and expand.

Question 20

Baking Soda and Vinegar Reaction

Students perform a chemistry experiment by mixing baking soda with vinegar. They mix 4 grams of baking soda with 50 grams of vinegar in a 6-gram plastic cup as shown below. The cup is left uncovered. The students record the mass and temperature of the mixture every 5 seconds. They continue these observations until 10 seconds after they see the mixture stop bubbling. Their data are shown in the table below.

The data in the table show the temperature of the cup-baking soda-vinegar system. The temperature of the surrounding air was not measured.

Assuming that the total amount of energy remains constant, what conclusion about energy transfer does the temperature data support?

[pic]A. Thermal energy was lost from the surrounding air and the system.

[pic]B. Thermal energy was gained by the system and the surrounding air.

[pic]C. Thermal energy was transferred from the surrounding air to the system.

[pic]D. Thermal energy was transferred from the system to the surrounding air.
