  • A. Arthur Tansely

Correct Answer: Option D - In 1972, Charles Elton, an English ecologist, coined the term 'pyromid of numbers', which represent the total number of individuals (population) at each trophic level. The pyramid shape is used because it typically shows a large number of producers at the bottom and progressively fewer organisms at higher trophic levels. Charles Elton's introduction of this term was significant in the field of ecology as it helped in understanding the structure and function of ecosystems.
