Answer Key with Questions

Leswn Flow of Energy

Answers may vary

Explanation

a. 1 - frog. 2 - snake. 3 - cricket, 4 - grass. 5 - soil bacteria

b. Matter is recycled and energy flows one way. starting with input from the Sun

Cycling Of matter: The matter recycles among the prcxfucer (grass). consumers (cricket. and snake). and (soil bacteria). The grass uses molecules from the air and soil (carbon dioxide, water) to get the matter to make the sugar The cricket eats the grass, the frog eats the cricket, and the snake eats the frog. Each animal gets matter [cartx)n compounds] to make the molecules they need from their fcXd. When all these organisms die, the 9il bacteria (decomgx»sers) break down the carbon compounds from the organisms' t»dies and so this matter available for use by other organisms

 Flow of energy: The grass (producer) absorbs energy from the Sun and stores this energy within sugars (complex cartxn compounds). When the cricket eats the grass, the frog eats the cricket, and the snake eats the frog, each animal gets energy for life processes by breaking down food molecules. The grass. the cricket, the frog. and the snake all release energy as heat. When all these organisms die. the soil (decomposers) break down the carbon compounds in the organisms' bcxiies to get energy for life processes. The soil bacteria (decomposers) also release heat as they use energy. The heat is not available to organisms in the ecosystem to use for energy. This is why continual energy input from the Sun is necessary for the organisms in the ecosystem to live

Evidence of understanding

Student provides clear evidence of using the dimensions* to make sense of scientific phenomena and / or to design solutions to problems. Student is able to

 complete the table to explain the food web

AND

 describe the cycling of matter and flow of energy within the ecosystem

Student provides partial evidence of using the dimensions * to make sense of scientific phenomena and / or to design solutions to problems. The response lacks some critical information and details contains sorne errors Student is able to

complete the table to explain the food web AND descritk the cycling of matter and the flow of energy within the ecosystem BUT the table OR the description is incomplete or incorrect  is imomplete or provides minimal evince of using the mensions• to make sense of scientific phenomena and / or to design solutions Student does not respond or student response is inaccurate, irrelevant, or contains insufficient evidence of using the dimensions* to make sen* of scientific phenomena and / or to design solutions to problems

 

As outlined in the Perforrmrxe Expectatons (PE) o / the NGSS, the three dimensions are the dsOpiinary aye ideas (00), scence and (SEP), and (CCO Note that due to the Of the assessment Items may address all three dnrnsöns

Scoring Notes

Possible answers include

a. 1 - frog. 2 - snake, 3 - cricket. 4 - grass, 5 - soil bacteria

b. Matter is recycled and energy flows one way, starting with input from the Sun

 Cycling of matter: The matter recycles aru)ng the producer (grass). consumers (cricket. frog and snake), and decomposers (soil bacteria). The grass uses rnolecules from the air and soil (carbon dioxide, water) to get the matter to make the sugar molecules. The cricket eats the grass, the frog eats the cricket, and the snake eats the frog. Each animal gets matter (carbon compounds) to make the nu»lecules they need from their food. When all these organisms die, the soil bacteria (decomposers) break down the carbon compounds from the organisms' bodies and so this matter becomes available for use by Other organisms

 Flow Of energy: The grass (producer) absorbs energy from the Sun and stores this energy within sugars [complex carbon compounds). When the cricket eats the grass, the frog eats the cricket, and the snake eats the frog, each animal gets energy for life processes by breaking down food molecules. The grass, the cricket, the frog. and the snake all release energy as heat. When all these organisms die, the soil bacteria (decomposers) break down the carbon compounds in the organisms' bodies to get energy for life processes. The soil bacteria (decomposers) also release heat as they use energy. The heat is not available to organisms in the ecosystem to use again for energy. This is why continual energy inshJt from the Sun is necessary for the organisms in the ecosystem to live
