A terrarium can server as a model ecosystem. Many terrariums contain rocks, soil, a soft soil covering that can absorb water, and a few small plants. A student constructed a terrarium using a glass jar as shown in the picture.
Picture description: A glass jar with a layer of rocks at the bottom, layer of soil, soil covering and small plants. The glass jar is open and there is a water spray bottle spraying a small amount of water.
Drag the item on the left to the matching transfer of energy of matter. Hint: Some may apply to both.
Answers to drag:
Plants increase in size, producing new leaves and stems.
Sunlight caused the temperature to increase.
The number of water droplets decreased during the day.
Transfer of Energy Transfer of Matter
Answer by dragging items in these sections. Answer by dragging items in these sections.
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.
The student sprayed a small amount of water into the terrarium, placed a thermometer inside, and then sealed the terrarium with a lid. Next, the terrarium was placed on a table where it was exposed to sunlight. The student checked the terrarium a few times each day for one month. During that time the plants produced new stems and leaves. The student noticed that water droplets formed on the inside of the glass jar. The number of droplets was greatest on sunny days and was usually greater in the morning than in the evening. The student also observed that the temperature inside the terrarium was highest during the day when the sun was shining.
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 temperature inside the terrarium was higher during the day.
The plants slowly increased in size over the month of observation.
The plants produced enough energy from food to grow new stems and leaves.
The amount of water that formed on the inside of the jar was greatest on sunny days
The amount of water that formed on the inside of the jar was greatest on sunny days.

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 student wrote a statement about the terrarium. Complete the sentences by selecting the correct answers in the blank. During the daytime, the terrarium (produces/reflects/absorbs) light energy, which (increases/decreases/stabilizes) the thermal energy in the terrarium. This change in energy (increase the amount of water/helps the water move/decreases the amount of water) within the terrarium. The collection of water inside the terrarium shows that matter is (recycled/reduced/produced) as energy flows in the system.
During the daytime, the terrarium absorbs light energy, which increases the thermal energy in the terrarium. This change in energy increases the amount of water within the terrarium. The collection of water inside the terrarium shows that matter is recycled as energy flows in the system.

The student constructs another terrarium with rocks, soil, and plants, but this time earthworms are added to the ecosystem. Earthworms release nutrients into the soil. The students adds water, seals the lid, and places the terrarium where it is exposed to sunlight. In what ways will the addition of earthworms most likely affect the terrarium ecosystem?
Move the correct answer to each box. Not all answers will be used.
Even though the earthworms will benefit the plants by providing _____, they will also compete with the plants for limited _______
