The term "ecosystem" was coined by British botanist A.G. Tansley in 1935. He described an ecosystem as the whole system of living things (biotic) plus their physical surroundings (abiotic) working as one unit. Memory hook: "Tansley Tied the System together" - both start with T.
Tansley coined the term ecosystem in 1935. Do not confuse him with Haeckel (ecology), Odum (developed ecosystem ecology), or Warming (plant ecology).
Your doubts, answered
Who exactly coined the term ecosystem?
A.G. Tansley, a British botanist, coined the term ecosystem in 1935. He combined the living community and its non-living environment into one working unit. This single name is what NEET tests, so remember Tansley = ecosystem.
Is it Tansley or Odum who coined the term ecosystem?
Tansley coined the actual word ecosystem in 1935. E.P. Odum did NOT coin the word, he later developed and popularised modern ecosystem ecology and wrote famous textbooks on it. NEET options put both together to trap you, so pick Tansley for who coined the term.
Did Haeckel coin the term ecosystem?
No. Ernst Haeckel coined the term ECOLOGY (1866), not ecosystem. Students mix these up because both start with 'eco'. Haeckel = ecology, Tansley = ecosystem. Keep the two names apart for the exam.
What about E. Warming, did he coin ecosystem?
No. Eugene Warming is linked with plant ecology and wrote an early book on plant communities, but he did not coin the word ecosystem. He is added as a wrong option to test if you truly know Tansley.
When was the term ecosystem coined?
The term was coined in 1935 by Tansley. Knowing the year helps because some questions ask for both the person and the year together.
Who is called the father of ecosystem ecology?
Tansley coined the word, but E.P. Odum is often called the father of modern (ecosystem) ecology for developing the field. For 'who coined the TERM', the answer is always Tansley; for 'developed modern ecosystem ecology', think Odum.
⚠️ The NEET trap ✗ Choosing E.P. Odum because his name is famous in ecosystem ecology. ✓ A.G. Tansley coined the term ecosystem in 1935; Odum only developed the field later. 🧠 Coined = Tansley. Developed = Odum. The question word 'coined' points to Tansley every time.
Real NEET questions
NEET 2016
The term ecosystem was coined by:
A · E.P. Odum
B · A.G. Tansley ✓
C · E. Haeckel
D · E. Warming
Solution: The term 'ecosystem' was coined by A.G. Tansley in 1935, so option (B) is correct. E.P. Odum developed modern ecosystem ecology, E. Haeckel coined the term 'ecology', and E. Warming is linked with plant ecology. All three wrong options are famous ecologists placed to confuse you, but only Tansley coined this exact term.

The term ecosystem was coined in 1935 by A.G. Tansley.
What is the difference between ecology and ecosystem in terms of who named them?
Haeckel coined 'ecology' in 1866, while Tansley coined 'ecosystem' in 1935. Two different scientists, two different terms.
Why is this a common NEET question?
NEET often asks history-of-the-term facts because they are easy to test with four scientist names. Knowing Tansley = ecosystem gives you a quick, sure mark.
Does NCERT print that Tansley coined the term?
NCERT frames the ecosystem as a functional unit of nature. The exact attribution to Tansley is standard textbook knowledge and a frequent NEET point, so learn it directly.
