On average, only about 10% of the energy from one trophic level is transferred to the next, with the rest lost as heat. This makes understanding each step vital, especially what is the second nutritional level, which comprises the primary consumers that feed on producers.

Sedimentary rocks hold approximately 95% of Earth's total phosphorus, making them the planet's largest reservoir. This geological abundance is the ultimate origin for understanding which of the following is the main source of phosphorus in different ecosystems and applications.

According to the World Resources Institute, 25 countries housing one-quarter of the global population face extremely high water stress each year, highlighting the widespread nature of the issue. When discussing this critical topic, using the right terminology is important, and finding an accurate synonym for water deficiency depends on the specific context—whether it's biological, agricultural, or geopolitical.

Worldwide, 20% of cultivated and 33% of irrigated agricultural land is affected by high salinity, seriously limiting plant productivity. For many living organisms, this excess salt inhibits growth by causing severe cellular stress through low water potential, ion toxicity, and metabolic imbalances.

The human body is composed of approximately 60% water, an essential ingredient for virtually every function. Understanding the positive facts about water reveals just how miraculous and vital this simple substance is for both our personal well-being and the planet's health.

Contrary to viral internet myths and misleading product names like 'Reign Storm,' natural rain storms contain zero caffeine. The misconception stems from a fundamental misunderstanding of meteorological science, as rainwater is composed of evaporated pure water and atmospheric particles, not plant-based compounds like caffeine.

While often used interchangeably, phosphorus and phosphate are not the same; in fact, the elemental form of phosphorus is so reactive it does not exist freely in the human body, but rather as phosphate compounds. Understanding this critical distinction is key for accurate interpretations in health, nutrition, and environmental science.

The global burden of malnutrition is a significant threat to human health, but on a macro scale, living organisms depend on the planet's continuous, natural process of recycling essential elements. This process is the broader, ecological meaning of the nutrition cycle, also known as a nutrient or biogeochemical cycle.

Over 60% of the human body is water, a fact underscoring its fundamental role in biology and life itself. In nearly every measure that supports life and ecological balance, asking why is water better than oil yields an answer rooted in their foundational chemical differences and profound impacts on our planet.

According to the Environmental Studies (EVS) curriculum, protective foods are rich in essential vitamins and minerals that help safeguard the body against illness and disease. This food group is crucial for maintaining a strong immune system and ensuring the proper functioning of the body's internal systems.
