It refers to microorganisms (bacteria, viruses, fungi) not visible to naked eye but impacting health, decomposition, and nutrient cycles significantly.
Health is complete physical, mental, and social well-being. It requires balanced diet, hygiene, exercise, and stress-free environment.
Contact forces require physical touch (friction, muscular). Non-contact forces act from distance (magnetic, gravitational, electrostatic).
Air column height decreases, so fewer air particles exert less weight. This causes lower pressure and affects breathing.
Elements contain one type of atom (e.g., iron). Compounds contain two or more elements chemically bonded (e.g., water – H₂O).
When parallel light rays pass through a convex lens, they converge at the focal point. A real inverted image forms.
Bees pollinate flowers while collecting nectar. Plants get reproduced; bees get food. This mutualism maintains ecological balance.
Warm moist air over oceans rises, creating low pressure. Surrounding high-pressure air rushes in, causing spiraling winds and cyclonic circulation.
Solute is the substance dissolved (e.g., sugar). Solvent is the dissolving medium (e.g., water). Together they form a solution.
Particles at liquid surface gain kinetic energy, overcome intermolecular forces, and escape as gas – even below boiling point.
