Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
(A) Humus — this matches (II) Dark-colored amorphous substance. Humus forms by humification during decomposition. It resists microbes, breaks down very slowly and stores nutrients in the soil.
(B) Detritus — this matches (III) Dead remains of plants and animals. Dead leaves, bark, flowers and the remains of animals and their faecal matter are the raw material for decomposition.
(C) Producers — this matches (IV) Phytoplankton. In water the phytoplankton are the green plants that make food by photosynthesis.
(D) Biomass — this matches (I) Mass of living organisms. Biomass is the weight of living matter at a trophic level or in an area.
