Biology Decoder: The Living World
Phase 1: The Foundation (What is an Ecosystem?)
An ecosystem is a biological community of interacting organisms and their physical environment.
1. The Energy Flow (Food Chain)
- Producers: Plants (Make their own food).
- Consumers: Animals (Eat others).
- Decomposers: Fungi/Bacteria (Clean up the dead).
- 10% Rule (Lindeman's Law): Only 10% of energy passes to the next level in a food chain.
Phase 2: The Core Logic (Microbes in Welfare)
1. The Good Microbes
| Microbe | Type | Usage |
|---|
| Lactobacillus | Bacteria | Turning Milk into Curd. |
| Yeast | Fungi | Making Bread, Alcohol (Fermentation). |
| Penicillium | Fungi | Making the first Antibiotic (Penicillin). |
| Rhizobium | Bacteria | Fixing Nitrogen in plants (Pulses). |
Phase 3: The Exam Edge (Evolution & Environment)
1. Evolution (The Story of Change)
- Charles Darwin: Proposed "Natural Selection". Origin of Species.
- Jean-Baptiste Lamarck: Proposed theory of "Use and Disuse" (Wrong theory, but important for exams).
- Vestigial Organs: Organs that were useful for ancestors but not for us (Appedix, Wisdom teeth).
2. Biodiversity & Pollution
- Endangered Species: Red Data Book (IUCN).
- Acid Rain: Caused by Oxides of Sulfur & Nitrogen.
- Global Warming: Caused by Methane (CH4) & CO2 trapping heat.
