Cycling of matter: The matter recycles among the producer (grass), consumers (cricket, frog, and snake), and decomposers (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 [carbon compounds] to make the molecules 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 input from the Sun is necessary for the organisms in the ecosystem to live
