What you’ll learn

Matter Goes AroundExplain that matter is conserved and cycles, while energy flows one way.Matter is anything that takes up space and has weight. In nature it is never created or destroyed, only changed in form and recycled through living things. Matter cycles in loops, but energy from the Sun flows one way and is lost as heat, so new energy must keep arriving.
The Water CycleDescribe the stages of the water cycle and explain that the same water is reused.Water cycles through evaporation, condensation, precipitation, and collection, repeating without end. Because water is recycled rather than made new, the water on Earth today is the very same water that has existed for millions of years, which is why keeping it clean matters.
The Carbon and Nutrient CyclesTrace the carbon cycle and describe how decomposers recycle nutrients.Carbon cycles as plants take it from the air, animals eat plants, and breathing and decay return it to the air. Nutrients cycle when decomposers break down dead matter and return building blocks to the soil for new plants. Water, carbon, and nutrient cycles all connect to keep ecosystems supplied.

Questions this course answers

What happens to matter in nature?

Matter is not created or destroyed; it changes form and cycles through nature again and again.

How is energy different from matter in nature?

Energy flows one way from the Sun and is lost as heat, while matter cycles and is reused.

Which is the correct order of the water cycle?

Water evaporates, then condenses into clouds, then falls as precipitation, then collects, and repeats.

Why do scientists say Earth's water is very old?

Because water cycles, the same water has been reused for millions of years; no new water is made.

In the carbon cycle, how do plants get carbon?

Plants take carbon dioxide from the air and use it to build their leaves, stems, and roots.

What do decomposers do in the nutrient cycle?

Decomposers break down dead plants and animals, returning nutrients to the soil for new plants.
