Which of the following statements about pollination is INCORRECT? MCQ with Answer and Explanation

Explanation:
Lactobacillus is a lactic acid bacterium that ferments lactose in milk, producing lactic acid that coagulates proteins to form curd. Saccharomyces cerevisiae (baker's yeast) undergoes anaerobic respiration, producing CO2 gas that causes bread dough to rise. Aspergillus niger, a fungus, is widely used in industrial fermentation for the large-scale production of citric acid. All statements are correct.

Explanation:
Sunlight is the ultimate source of energy for almost all ecosystems. Photosynthetic autotrophs (plants, algae, cyanobacteria) capture solar energy and convert it into chemical energy, which then flows through the food web. Some deep-sea ecosystems rely on chemosynthesis from hydrothermal vents, but globally, the sun drives the biosphere.
