In the context of organic chemistry, which of the following statements is true regarding the role of herbivores and carnivores in a food chain?
A
A food chain can exist without herbivores but not without carnivores.
B
A food chain can exist without carnivores but not without herbivores.
C
A food chain can exist without herbivores and carnivores if it relies solely on decomposers and producers.
D
Herbivores and carnivores are essential for the existence of any food chain.
Verified step by step guidance1
Understand the basic structure of a food chain: it typically consists of producers, consumers (herbivores and carnivores), and decomposers.
Recognize that producers, such as plants, are the foundation of any food chain as they convert solar energy into chemical energy through photosynthesis.
Identify the role of herbivores: they are primary consumers that feed on producers, transferring energy to higher trophic levels.
Identify the role of carnivores: they are secondary or tertiary consumers that feed on herbivores or other carnivores, further transferring energy up the food chain.
Consider alternative food chain structures: a food chain can exist with only producers and decomposers, as decomposers break down organic matter, recycling nutrients back to producers, thus maintaining the ecosystem without the need for herbivores or carnivores.
