Classification of Elements in Nature
📌 All things in nature are divided into two components: abiotic (non-living things) and biotic (living things).
☀️ Non-living things (abiotic) are characterized by the inability to breathe, adapt, reproduce, or move independently.
🧪 Non-living matter is often referred to as substances, categorized by physical state into solid, liquid, and gas.

Characteristics of Living Organisms (Biotic)
💨 Living organisms breathe, consuming oxygen to burn food and produce energy for daily activities.
💧 The process of burning food generates water ($\text{H}_2\text{O}$) and carbon dioxide ($\text{CO}_2$), which are expelled when exhaling.
🍽️ Living things require food and drink to sustain life, grow, develop, and maintain energy.
♻️ Metabolism produces waste products that must be expelled through excretion, which can include urine, sweat, water vapor, and $\text{CO}_2$.

Movement, Sensitivity, Growth, and Reproduction
🏃 Movement is most easily observed in humans and animals.
💡 Living things are sensitive to stimuli (irritability), responding to physical or chemical changes, such as closing eyes to bright light.
🌱 All organisms—humans, animals, and plants—undergo growth and development, progressing through life stages (e.g., fetus to adult).
🧬 Reproduction occurs in two ways: generative (sexual) or vegetative (asexual).

Adaptation
🌱 Adaptation is the ability of a living thing to adjust to its environment.
🧩 Adaptation types include morphological, physiological, and behavioral adaptation.

Key Points & Insights
➡️ Living things are distinguished by seven core characteristics: breathing, requiring nutrition, excretion, movement, sensitivity to stimuli, growth/development, reproduction, and adaptation.
➡️ Energy production involves using oxygen to burn food, resulting in the waste products water ($\text{H}_2\text{O}$) and carbon dioxide ($\text{CO}_2$).
➡️ The ability to respond to external stimuli is called irritability, with stimuli categorized as chemical or physical.
