Transfer of Energy
Transfer of Matter
Transfer of Energy:
- Sunlight caused the temperature to increase.
Transfer of Matter:
- Plants increase in size, producing new leaves and stems.
- The number of water droplets decreased during the day.
Part A: Which statement describes a conclusion the student can draw from observations of the terrarium?
Plant roots capture more energy in the evening than in the morning.
Plants use nutrients from the soil to produce energy that helps them grow.
Energy from the sun helps water move from the plants and soil into the air inside the jar.
Water is cycled from the top to the bottom of the jar as the temperature inside the jar increases.
Plants use nutrients from the soil to produce energy that helps them grow.
Part B: Which statement describes evidence from the student's observations that supports the answer to Part A?
The evidence from the student's observations that supports the answer to Part A is: "Plant roots capture more energy in the evening than in the morning."
Which statements best describe characteristics of the model ecosystem inside the terrarium? Select TWO correct answers.
- Nutrients are recycled in the terrarium.
- The temperature inside the terrarium increases throughout the day.
Which statements best describe characteristics of the model ecosystem inside the terrarium? Select TWO correct answers.
Matter is lost in the form of heat as the plants grow in the model ecosystem.
Sunlight is an input that drives changes in the model ecosystem.
Water provides energy for the production of food by the plants.
Matter is created as water moves from the soil into the air of the terrarium.
Matter from water and soil gets recycled inside the jar but cannot leave the jar.
The correct answers are:
- Sunlight is an input that drives changes in the model ecosystem.
- Matter from water and soil gets recycled inside the jar but cannot leave the jar.
Use the model to show how carbon cycles through an ecosystem. Starting with "A grasshopper molts its exoskeleton, " put the remaining events in the correct order from top to bottom.
1. A grasshopper molts its exoskeleton.
2.
3.
4.
5.
6.
Drag and drop the correct choice into the blank spaces above
Here is the correct order:
1. A grasshopper molts its exoskeleton.
2. Bacteria decompose the grasshopper's exoskeleton, releasing carbon dioxide.
3. Plants absorb carbon dioxide from the air and use it during photosynthesis.
4. Animals consume plants, incorporating carbon into their tissues.
5. Animals and plants respire, releasing carbon dioxide back into the air.
6. Decomposers break down dead plants and animals, releasing carbon dioxide.
The process of cell respiration shown in this figure includes several events. Determine whether each event in the table is part of the process or not part of the process. Select all the correct answers.
Part of the Process
NOT part of the process
Some molecures are released during respiration.
Atoms combine to form new molecules.
Molecules keep their same arrangements.
Added energy causes atoms to break down.
Part of the Process:
- Some molecules are released during respiration.
- Added energy causes atoms to break down.
NOT part of the process:
- Atoms combine to form new molecules.
- Molecules keep their same arrangements.
A student makes a claim that an atom of carbon in a grasshopper's body could once have been an atom in the body of a prehistoric animal. Which evidence best supports this claim?
Figure 2 shows that grasshoppers molt their exoskeletons.
Figure 1 shows that carbon is present when energy is produced.
Figure 1 shows that carbon atoms are used in more than one type of molecule.
Figure 2 shows that carbon continually circulates through the ground, the atmosphere, and living things.
The evidence that best supports the claim is:
- Figure 2 shows that carbon continually circulates through the ground, the atmosphere, and living things.
Part A: The equation shows a reaction that occurs during the decomposition of a grasshopper's body. In which way does this process compare to the cell respiration process in Figure 1?
Both processes release extra oxygen into the atmosphere.
One process is the reverse of the other process.
Both processes result in the same types of molecules being produced.
One process produces larger molecules than the other process.
The correct answer is: One process is the reverse of the other process.
Part B
Which statements about both the decay and cell respiration processes are true?
Choose two correct answers.
Atoms are broken down to produce energy.
No atoms are lost during the chemical reaction.
New atoms are produced through chemical change.
Different types of atoms are needed for each new substance.
Atoms are rearranged to form different compounds.
The correct statements are:
- Atoms are broken down to produce energy.
- Atoms are rearranged to form different compounds.
