Answer 1

The correct option is C Producers

Ponds and lakes are stationary fresh water ecosystems. Ponds and lakes are characterised by maximum number of producers. Producers include phytoplanktons (e.g., diatoms, desmids, Chlorella, Chlamydomonas, Spirogyra, Oedogonium, Zygonema), free floating macrophytes (e.g., Lemna, Pistia, Azolla), suspended macrophytes (e.g., Utricularia, Ceratophyllum, Hydrilla), submerged anchored plants (e.g., Vallisneria), floating leaved anchored plants (e.g., Nelumbo, Nymphaea) and emergent plants (e.g., Sagittaria, Phragmites etc.).
