What is the main difference between Food Chain and Food Web?

The main difference between Food Chain and Food Web is based on definition: Food Chain — Linear sequence of organisms where each is eaten by the next. Food Web — Network of interconnected food chains in an ecosystem. Energy transfer follows 10% law (Lindeman's efficiency) — only 10% passes to next trophic level (NCERT Ch. 14)

Which is more important for NEET — Food Chain or Food Web?

Both Food Chain and Food Web are equally important for NEET as NTA tests their comparison directly. This topic falls under Ecosystems. Key points to remember: Energy transfer follows 10% law (Lindeman's efficiency) — only 10% passes to next trophic level (NCERT Ch. 14). Grazing food chain starts from producers; detritus food chain starts from dead organic matter. In aquatic ecosystems, major energy flow occurs through the detritus food chain.

Difference Between Food Chain and Food Web — NEET Biology

The main difference between food chain and food web is that a food chain is a single linear sequence of organisms through which energy flows, while a food web is a network of interconnected food chains in an ecosystem. NTA tests this within the Ecology unit, asking about trophic levels, energy flow (10% law), and why food webs provide greater ecosystem stability.

Comparison Table: Food Chain vs Food Web

Basis	Food Chain	Food Web
Definition	Linear sequence of organisms where each is eaten by the next	Network of interconnected food chains in an ecosystem
Pathway	Single, straight pathway of energy flow	Multiple, branching pathways
Number of organisms	Limited — involves 4–5 trophic levels typically	Involves many organisms across multiple food chains
Ecosystem stability	Disturbance in one level affects the entire chain	More stable — alternative pathways compensate for loss
Trophic levels	Each organism occupies one trophic level	An organism can occupy different trophic levels
Energy flow	Unidirectional and linear	Unidirectional but through multiple routes
Types	Grazing food chain, detritus food chain	No specific types — it is the combined network
Complexity	Simple and easy to study	Complex — represents realistic feeding relationships
Example	Grass → Grasshopper → Frog → Snake → Eagle	All interconnected food chains in a grassland ecosystem

Key Points to Remember

Energy transfer follows 10% law (Lindeman's efficiency) — only 10% passes to next trophic level (NCERT Ch. 14)
Grazing food chain starts from producers; detritus food chain starts from dead organic matter
In aquatic ecosystems, major energy flow occurs through the detritus food chain
Food webs provide ecosystem stability — loss of one species doesn't collapse the system
Standing crop = biomass at each trophic level — decreases at higher levels (pyramid of biomass)

NEET Exam Tip

How NTA Tests ThisNTA commonly asks: 'Which statement about food webs is correct?' — the key answer is that food webs increase ecosystem stability by providing alternative pathways. Also expect 10% rule calculations: 'If producers have 10,000 J, how much energy reaches tertiary consumers?' (10 J). Match-the-column linking organisms to trophic levels is frequent.
