NEET BIOLOGY

Detailed explanation-1: -Producers. Primary producers-including bacteria, phytoplankton, and algae-form the lowest trophic level, the base of the aquatic food web. Primary producers synthesize their own energy without needing to eat. Many photosynthesize, using the sun’s energy to build carbohydrates.

Detailed explanation-2: -Phytoplankton are the tiny, plant-like producers of the plankton community. They include bacteria and algae that form the base of aquatic food webs. Common phytoplankton include diatoms, dinoflagellates, cyanobacteria (blue-green algae), and green algae.

Detailed explanation-3: -They also require trace amounts of iron which limits phytoplankton growth in large areas of the ocean because iron concentrations are very low.

Detailed explanation-4: -They are what is known as primary producers of the ocean-the organisms that form the base of the food chain. Because they need light, phytoplankton live near the surface, where enough sunlight can penetrate to power photosynthesis.

Detailed explanation-5: -Five producers in the ocean include an assortment of photosynthetic and chemosynthetic organisms. Seaweed, kelp, seagrass and phytoplankton are photosynthetic organisms that can create glucose as their own food source by using sunlight and water to convert carbon dioxide into glucose (a sugar molecule).
