Which of the following shows the correct sequence in food chain?
Answer Details
The correct sequence in a food chain is: plants -> herbivores -> carnivores -> decomposers.
Plants are at the bottom of the food chain because they are producers that convert energy from the sun into food through photosynthesis. Herbivores, such as cows or deer, eat the plants to obtain energy and nutrients. Carnivores, such as lions or eagles, eat the herbivores to obtain energy and nutrients. Finally, decomposers, such as bacteria and fungi, break down the dead bodies of plants and animals, returning nutrients to the soil so that plants can grow again.
This sequence of plants -> herbivores -> carnivores -> decomposers is called a food chain. Each level of the food chain is called a trophic level. The higher up the trophic levels you go, the fewer organisms there are because energy is lost at each level due to respiration, waste production, and other factors.
In summary, the correct sequence in a food chain is: plants -> herbivores -> carnivores -> decomposers, with each level being a trophic level that is characterized by a specific group of organisms that obtain energy and nutrients from the previous level.
