DAUR BIOGEOKIMIA: ANIMASI PEMBELAJARAN SINGKAT SIKLUS DAUR SULFUR/BELERANG

Summary

Around 200 years ago, a French chemist discovered sulfur, a non-metal element found naturally in volcanic areas. Sulfur is essential in producing sulfuric acid and plays a key role in the sulfur cycle in nature. Volcanic eruptions release sulfur gases that form acid rain, which is absorbed by the soil and taken up by plants. Decomposing plants and animals release sulfur compounds that bacteria break down, producing forms of sulfur that are usable by plants or can be toxic in anaerobic conditions. Sulfur is also present in fossil fuels, used in industrial processes.

Takeaways

• 😀 Around 200 years ago, a French chemist discovered sulfur, now known as an essential element in chemistry.
• 😀 Sulfur, also called sulfur, is a non-metal element that is naturally found as a yellow crystalline solid.
• 😀 Sulfur can be found in pure form or as a mineral, especially near volcanic areas.
• 😀 Sulfur is widely used by humans, particularly as a raw material for sulfuric acid production.
• 😀 In biology, sulfur undergoes a biogeochemical cycle known as the sulfur cycle.
• 😀 When a volcano erupts, sulfur is released in the form of sulfur dioxide gas and hydrogen sulfide.
• 😀 These sulfur gases interact with water in the atmosphere to form sulfuric acid, contributing to acid rain.
• 😀 Sulfuric acid is absorbed by the soil and taken up by plants as sulfur for the food chain.
• 😀 When plants and animals die, organic compounds like hydrogen sulfide are decomposed by bacteria, producing inorganic sulfate and sulfur compounds.
• 😀 In aerobic environments, bacteria produce sulfate, which plants can use, while in anaerobic conditions, toxic sulfide compounds are formed, found in volcanic magma.
• 😀 Fossil fuels containing sulfur, such as those from buried ancient life, are used as fuel by industries.

Q & A

What was discovered around 200 years ago by a French chemist?

A French chemist discovered sulfur, which was found through the process of extraction and chemical analysis.

What is sulfur, and what are its main characteristics?

Sulfur (or sulfur) is a non-metal element that naturally occurs as a yellow crystalline solid. It can be found in its pure form or as a mineral, especially in volcanic areas.

How is sulfur utilized by humans?

Sulfur is widely used by humans as a raw material for producing sulfuric acid.

What is the sulfur cycle in biology?

The sulfur cycle is a biogeochemical cycle in biology, which describes the movement of sulfur through various processes in nature, including volcanic activity, plant absorption, and decomposition.

What happens when a volcano erupts in relation to sulfur?

When a volcano erupts, it releases sulfur in the form of sulfur dioxide and hydrogen sulfide gases. These gases then interact with the atmosphere and water droplets.

How does sulfur dioxide contribute to acid rain?

Sulfur dioxide and hydrogen sulfide gases combine with water droplets in the atmosphere to form sulfuric acid, which, when saturated, leads to acid rain.

What happens to sulfuric acid once it reaches the soil?

Once sulfuric acid reaches the soil, it is absorbed by plants in the form of sulfur, which is then integrated into the food chain.

What occurs to sulfur compounds after plants and animals die?

When plants and animals die, organic compounds such as hydrogen sulfide are broken down by decomposers into inorganic sulfate through both aerobic and anaerobic processes.

How does aerobic decomposition of sulfur affect the environment?

Aerobic decomposition produces inorganic sulfate, which is used by plants to complete the sulfur cycle.

What happens during anaerobic decomposition in the sulfur cycle?

Anaerobic decomposition produces toxic sulfur compounds like sulfides, which are found in magma and contribute to volcanic sulfur emissions.
