The cell membrane is made from a double layer of lipids called “phospholipids.” Which element is implied by the prefix “phospho?” Mito- chondria Cell membrane Rough ER Phosphorus Potassium Plutonium glucose glucose glucose waste waste waste correct correct Hint: What does the mitochondria create?

- 6. Why is PhosphorusImportant? Our cells need phospholipids, DNA, and ATP. They each have phosphorus in them. So where does the phosphorus come from? Phosphorus come from rocks. Rocks are solid lumps of minerals, and some of those minerals are phosphorus. So when rocks crumble and erode, phosphorus is released from the rocks. The weather causes rocks to crumble. Wind, cold, and rain cause dust sized fragments of rocks to chip off, thus releasing phosphorus into the ground Back Home https://ciaaw.org/phosphorus.htm https://www.99.co/blog/indonesia/pondasi-batu-kali/
- 7. Make it Rain! Theweather causes phosphorus to be released from rocks. Click the cloud to make it rain. Small bits of phosphorus are released into the ecosystem due to the weather. Click the cloud to make it stop raining. Now that there is phosphorus in the soil, click on the land organism that can absorb it through their roots. PPPPPP Snails don’t have roots. Roots… think roots Back Home
- 8. The Producers Of course!Plants simply absorb the phosphorus through their roots. Click on the roots to proceed. Now that plants have phosphorus they can use it to make their DNA, ATP, and phospholipids. Click on the herbivore (primary consumer) in the diagram.P P P P P P Decomposers feed on the dead. This plant is alive. Back Home
- 9. The Consumers Of course!The snail is an herbivore so it eats the plant. This is how animals get the phosphorus to make their DNA, ATP, and phospholipids. Phosphorus simply moves up the food chain. Which organism would likely eat snails? P P P P P P P PP Maybe accidentally, but cows are herbivores too. Wolves are hunters. I don’t think they would hunt snails. Back Home https://id.wikipedia.org/wiki/Siput
- 10. Up the FoodChain The snail eats the plant… The frog eats the snail… Which would likely eat the frog? You got it. Phosphorus moves up the food chain. P P I’m an herbivore. I’m an herbivore. P Back Home
- 11. The Decomposers This wholething started with crumbling rocks…remember? Decomposers are organisms such as mushrooms and bacteria. They have DNA, ATP, and phospholipids also, so that means they need phosphorus too. Will decomposers feed on dead plants? You got it. Will they feed on dead snails? We’re almost done. PP P P P P P P P yes no P yes no Like any organism, decomposers make waste. They release their waste into the ecosystem. Some of their waste even contains phosphorus. P Examine the picture… if decomposers release phosphorus into the soil, which organism can reuse the phosphorus? The plants The rocks The snails I hope you see why it’s called the phosphorus cycle. Rocks aren’t organisms What do snails eat? Back Home
- 12. The Human Factor Sadly,human actions are disrupting the phosphorus cycle. Humans, like this farmer, routinely add extra phosphorus to soil because phosphorus is a fertilizer. What do you think the extra phosphorus does for the farmer’s crops? P P P P P PPPPPP Kill weeds Kill bugs Stimulates growthNo. Weed killer kills weeds. No. Pesticides kill bugs. Yes, exactly! So if phosphorus helps crops grow, why is this bad? Back Home
- 13. Why is thisBad? The extra phosphorus is intended to help crops grow better, but often the phosphorus is washed away into rivers, lakes, and ponds when it rains. P P P P PP PThe extra phosphorus got washed away and is collecting in this pond. Since the phosphorus is a fertilizer, it causes algae in the pond to grow at an extreme rate. These extreme algae growths are called “algal blooms.” As the algae eventually die, the decaying process uses up the oxygen in the pond, thus all the fish die. Once the fish die, so does the rest of the ecosystem. Make it rainRain Rain Go Away Back Home
