Students grew several healthy plants in their classroom. All of them were planted in healthy soil, placed in a sunny window, and watered once a week. After the plants grew, the students set up four experiments to see which conditions affected plant growth the most. For each experiment, students kept the same conditions for Plant A and changed the conditions for Plant B. The results of the experiment are below. Based on the evidence from their findings, which of the following is true?
Plants obtain most of the materials they need to grow from soil and sunlight.
Plants obtain most of the materials they need to grow from water and plant food.
Plants obtain most of the materials they need to grow from sunlight and water.
Plants obtain most of the materials they need to grow from air and water.

The figure below shows an ecosystem with different plants and animals. What statement can you make about the flow of energy in this ecosystem?
On a cloudy day, no energy will flow in this ecosystem.
Grass can use and store energy from the sun, which eventually flows to all of the other lifeforms.
Eagles eat snakes, rabbits, and frogs and are not affected by the energy in other parts of the ecosystem.
If eagles are removed from the ecosystem, energy can no longer flow to any of the other animals.

A science teacher has grown an indoor garden for several years. Each year, students carefully water the plants, add plant food, make sure the garden gets plenty of sunshine, and remove any dead leaves or stems. This year, students have decided to care for the garden in all the same ways, except they have stopped using plant food. Instead, they rely on the decomposition of the dead leaves and stems to supply nutrients to the plants. However, their garden does not grow this year. Which explanation supports this result?
The dead leaves and stems are too big and need to be chopped up into smaller pieces.
The plants have become accustomed to plant food, and now they cannot use the nutrients from the dead leaves and stems.
The soil does not have enough nutrients because there is no longer enough matter for the decomposers to break down.
The dead leaves and stems are preventing the sunshine from reaching the soil, which is keeping the plants from growing.

Sonya builds a terrarium with different kinds of plants inside and then adds some crickets. Sonya wants to show how matter cycles within the terrarium. Which of the following actions could she take to show this?
Sonya could add worms and mushrooms to the terrarium. If a plant in the terrarium dies, these decomposers can recycle some materials back into the soil for the other plants to use.
Sonya could remove all of the larger plants in the terrarium. She could plant them in a larger pot so that all the plants have enough space to grow.
Sonya could add a lizard to the terrarium. The lizard may eat the crickets and leave droppings on the ground that will be absorbed back into the soil.
Sonya could add plant food to the terrarium. The plant food will provide nutrients to the soil to help the plants grow taller faster.
Sonya could add a light source to the terrarium. The light source will mimic the sun, which will make the plants grow at a faster rate.

Use the diagram to answer the question. An area has a large decrease in the deer population. How might this impact the ecosystem?
The rabbit population could increase because the cougars now only eat rabbits.
The population of mice could decrease, causing the snake population to decrease.
There could be less food for cougars to eat, which would cause a decrease in their population.
There could be an increase in both the cougar and snake populations because more grass will be available.
