Use the food chain below to answer questions 1 - 3.

Cane toads are a species of toad that is toxic to snakes. Cane toads will eat caterpillars. If cane toads are released into this ecosystem, what will happen to the population of frogs? Why?

Criteria For Success
Identify what the cane toad eats in the food chain.
Explain how adding the cane toad into the ecosystem affects the frogs.
If cane toads are released into this ecosystem, the population of frogs will _. This will happen because ___.

Use the food web below to answer questions 4 - 6.

Use the food web below to answer question 7.

The food webs above are from the same ecosystem but at different times.

In 2015, there was a fire which destroyed all of the plants.  Ecologists were able to bring back the grass after the fire.

Ecologists are concerned about this ecosystem because the number of rabbits, mice, grasshoppers, and birds has not grown since the fire and have started to decrease.

Using what you have learned so far and the food webs above, write a scientific argument explaining why you think the numbers of rabbits, mice, grasshoppers, and birds have started to decrease.

Criteria For Success
Identify what caused the rabbits, mice, grasshoppers, and birds to decrease.
Explain why the number of rabbits, mice, grasshoppers, and birds decreased after the fire.

The numbers of rabbits, mice, grasshoppers, and birds has started to decrease because . In the food web, it shows . This means __.

Read the scenario below.  Use the information in the passage and picture to answer questions 8 – 9.

A fifth grader named Shayleah decides to study plant growth at home.  Shayleah buys five plants that are all the same height.  She plants them in five separate containers.  Each plant has different conditions, as shown below.  She brings a photograph of her experiment to school to show her class.

Carefully read the labels on plants #1, #2, #3, and #5. Will the plant grow or not grow? Fill out the table to share what you think will happen to each plant:

Plant #1 will .
Plant #2 will .
Plant #3 will .
Plant #5 will .

Her teammate Laron sees the photograph and says “Plant # 4 will die because plants cannot grow without soil.”

Do you agree or disagree with Laron’s claim?  Support your answer with evidence from the simulation.

Use evidence from the simulation to support your answer (how the sim shows what plants need to live and grow).
