How this was checked
Three evidence sources: every section compared against every other section for repeated sentences and long shared runs of wording; a scan for recycled filler phrasing; and 75 distinctive sentences, one per section, run as exact-phrase web searches with each result compared word by word. A run of six or more matching words counts as a finding.
Sources checked: State Examinations Commission papers and marking schemes, NCCA Leaving Certificate Biology specification, simplestudy.com, studyclix.ie, revisewise.ie, BBC Bitesize, Wikipedia, General web (open search, no site restriction).
This is an evidence-based audit, not a commercial plagiarism scan. Specification learning outcomes, standard definitions, balanced equations and SEC command words are recorded as unavoidable overlap and do not affect a topic's score.

Close paraphrase3. Pyramids of Numbers and Biomass
A pyramid of biomass shows the total dry mass of living material at each trophic level.
The definition follows the same word order as the encyclopaedia entry. It is a standard definition, but the run of matching words is long enough to be worth rewording.
Likely source: Wikipedia - Biomass (ecology) / Biomass pyramid (10 of 14 words matched) view
Suggested rewrite
Put the measurement first and the reason second: "To draw a pyramid of biomass you dry a sample from each trophic level and weigh it, then draw each bar in proportion to that dry mass. Drying matters because water content varies hugely between organisms and would otherwise distort the comparison."

Unavoidable overlap1. What is Photosynthesis?
Photosynthesis is the process by which green plants make their own food by converting light energy into chemical energy.
This is the standard textbook definition of photosynthesis and the wording examiners expect. The overlap is limited to the definition itself, not the surrounding explanation.
