Detailed explanation-1: -Organisms in food chains are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers . Producers, also known as autotrophs, make their own food.

Detailed explanation-2: -Each food chain is a diagram including a series of arrows, each pointing from one organism to another and each organism or step represents a trophic level. For example, the producers form the first trophic level, herbivores feeding on the producers directly form the second trophic level and so on.

Detailed explanation-3: -Each step along a food chain is known as a trophic level or feeding level, and every organism can be categorized by its trophic level. The most basic trophic level is producers-plants such as underwater bay grasses and free-floating algae that make their own food through photosynthesis.

Detailed explanation-4: -Trophic Levels Level 1: Plants (producers) Level 2: Animals that eat plants or herbivores (primary consumers) Level 3: Animals that eat herbivores (secondary consumers, carnivores) Level 4: Animals that eat carnivores (tertiary consumers, carnivores)

Detailed explanation-5: -First Trophic Level: Autotrophs. Second Trophic Level: Primary Consumers. Third Trophic Level: Secondary Consumers. Fourth Trophic Level: Tertiary Consumers. Fifth Trophic Level: Quaternary Consumers.
