Which level of the food chain includes Typha bulrushes, Sagittaria, Hydrilla, Rupia, Chara, occurring in concentric layers from the periphery to the deep regions?

The correct answer is Producers.

Key Points

• Rooted plants occur in concentric layers from the periphery to the deeper zones.
• Some examples of rooted plants are Typha bulrushes, Sagittaria, Hydrilla, Rupia, and Chara.
• They are producers in the food chain.
• Producers:
  • Autotrophs are another name for producers.
  • They produce their own food.
  • Every food chain's initial level is comprised of them.
  • Plants or single-celled organisms are the majority of autotrophs.
  • The majority of autotrophs produce their "food" from sunlight, carbon dioxide, and water through a process known as photosynthesis.

Additional Information

• Primary consumers:
  • The second trophic level consists of primary consumers.
  • Herbivores is another name for them.
  • They consume primary producers, such as plants or algae. 
• Secondary consumers:
  • The majority of secondary consumers are carnivores.
  • They eat the primary consumers, which are herbivores.
  • These organisms are heterotrophs, more particularly, omnivores and carnivores.
• Decomposers:
  • Decomposers are creatures that perform decomposition or the breakdown of dead or decaying organisms.
