Students are doing an investigation using an aquarium to see what would happen to the plants and animals in an ecosystem that did not get enough sunlight. They use the same type, number, and size of plants and fish in each tank. Each tank is given a different number of hours of sunlight each day. What should they measure?

• the temperature of the water

• the growth of plants and animals

• how much food they feed the plants

• how much water they put in the tank

aghavan has two identical plants. He plants one outside in the ground. The other is growing indoors without direct light. Raghavan predicts the weight of the carbon dioxide and water taken in by the plant and the oxygen given off by the plant.

Raghavan notices that a rabbit family has been eating the outdoor plant and that small insects are eating the indoor plant. He sees a fox hunting rabbit, but nothing is eating the insects.

Raghavan predicted the weight of carbon dioxide and water taken in by the plant. He predicted the weight of oxygen given off by the plant. What should he predict for the weight of the sugar the plant made?

• 1.80 grams

• 3.46 grams

• 3.72 grams

• 5.64 grams
