Detailed explanation-1: -All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Detailed explanation-2: -The giant tube worms with bacteria found in large numbers near the deep hydrothermal holes or ducts are a good example of a chemosynthetic organism. They generate sugars and amino acids from carbon dioxide with hydrogen sulfide as the energy source.

Detailed explanation-3: -The ability to photosynthesize is found in both eukaryotic and prokaryotic organisms. The most well-known examples are plants, as all but a very few parasitic or mycoheterotrophic species contain chlorophyll and produce their own food. Algae are the other dominant group of eukaryotic photosynthetic organisms.

Detailed explanation-4: -Chemosynthetic Organism Chemosynthetic heterotrophs are those organisms that cannot produce their own food. They obtain energy from the chemical processes which occur in their body. Good examples of chemosynthetic heterotrophs would be fungi, bacteria, humans and animals.

Detailed explanation-5: -Thiobacillus, Beggiatoa, Nitrobacter, and Nitrosomonas are the best examples of chemosynthetic bacteria. Chemosynthetic bacteria oxidize inorganic compounds to obtain energy without using sunlight. Thiobacillus, Beggiatoa, Nitrobacter, and Nitrosomonas are the best examples of chemosynthetic bacteria.
