The whole idea, one bite at a time
Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
What an Ecosystem Is
Nature's working unit
Ecosystem = biotic components + abiotic components + their interactions.
↳ Living + non-living + interactions = ecosystem.
Biotic vs Abiotic
The stage and the actors
↳ Bio = life; a-bio = absent life.
The Food Chain
Who eats whom, in arrows
↳ A chain is energy's route; arrows follow the energy.
Trophic Levels
The four floors of the eating building
↳ Producers are always T1; count upward from them.
Plants Capture Only ~1%
Nature's tiny solar panel
Of all the sunlight falling on a leaf, green plants convert only about 1% into food energy. Even so, that 1% powers every forest, grassland and ocean chain on Earth.
↳ 1% of sunlight is the entire budget of life.

Ecosystems: Components, Producers, Consumers and Decomposers
What an ecosystem is, its biotic and abiotic parts, the jobs of producers, consumers and decomposers, natural vs artificial ecosystems, and why decomposers keep the world running.
- Environment = everything surrounding an organism — living and non-living — that affects its life.
- An ecosystem is a self-contained unit where living organisms (biotic) interact with each other AND with their non-living surroundings (abiot...
- Abiotic components: air, water, soil, sunlight, temperature, minerals. Biotic components: plants, animals, microorganisms.

Food Chains, Food Webs, Trophic Levels and the 10% Law
How energy travels from grass to tiger: food chains and webs, trophic levels, the ten percent law, why chains stay short, and biological magnification — the pesticide problem.
- A food chain is the sequence of organisms through which food (energy) passes: grass → deer → lion.
- Each step of the chain is a trophic level: producers = T1, herbivores = T2, small carnivores = T3, top carnivores = T4.
- Green plants capture only about 1% of the sunlight falling on their leaves.

Our Impact: Waste, the Ozone Layer and Garbage Management
Biodegradable vs non-biodegradable waste, the ozone layer and how CFCs punched a hole in it, the Montreal success story, and how to manage garbage — 3 Rs, composting, segregation.
- Biodegradable wastes are broken down by microorganisms: fruit peels, paper, cotton, wood, cow dung, food waste.
- Non-biodegradable wastes cannot be broken down by microbes: plastics, glass, metals, thermocol, synthetic fibres, many pesticides.
- Excess biodegradable waste causes foul smell and disease breeding grounds; non-biodegradable waste persists for centuries, chokes soil and d...

162 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Consider these statements about an ecosystem. I. It contains living organisms and the non-living surroundings they interact with. II. Air, water, soil and sunlight are its abiotic components. III. Plants, animals and microbes are its biotic components. IV. An ecosystem contains only its living members. Which statements are correct?
Advanced
A I, II and III only
B I and IV only
C II and IV only
D All four
Show answer & explanation
I, II and III only
Leaving out the non-living half would make the word useless — a pond's fish cannot be understood apart from its water, its light and its dissolved oxygen.
Which of these is an ABIOTIC component?
Beginner
A fungi
B grass
C sunlight
D deer
Show answer & explanation
sunlight
Sunlight is non-living; the rest are biotic.
Which of these is a BIOTIC component?
Beginner
A temperature
B bacteria
C minerals
D rainfall
Show answer & explanation
bacteria
Bacteria are living organisms.
Which statement best explains why producers are called the ENTRY POINT of energy into an ecosystem?
Advanced
A they are the most numerous organisms in every ecosystem
B they are the first organisms to appear in a new habitat
C they alone convert the Sun's energy into chemical energy that other organisms can use
D they are eaten by every other organism in the ecosystem
Show answer & explanation
they alone convert the Sun's energy into chemical energy that other organisms can use
Nothing else in the living world can capture sunlight. Every calorie a lion uses came through a green leaf at some point, however many steps back.
