food cycle

In a forest, a simple food cycle connects plants, insects, and birds.

Definition
  1. Noun:
    • (Ecology) A community of organisms where there are several interrelated food chains: A "food cycle" describes a complex network of interconnected food chains within an ecosystem, illustrating how energy and nutrients flow between different species.
Usage
  • The term "food cycle" is used in ecological and biological contexts to describe the interconnected feeding relationships within a community of organisms. It emphasizes the cyclical and web-like nature of energy transfer, as opposed to a simple linear chain.
Examples
  • Noun:
    • The coral reef's health depends on a delicate and complex food cycle.
    • Scientists studied the forest's food cycle to understand the impact of losing a top predator.
Advanced Usage
  • Conceptual Usage: The "food cycle" is a broader concept than a "food chain," highlighting that most organisms are part of multiple chains and that energy pathways form a web. It underscores the interdependence of all species within an ecosystem.
    • The introduction of an invasive species can disrupt the entire local food cycle.
Variants and Related Words
  • Food web (n): This is a more common synonym for "food cycle," describing the same network of interconnected food chains.
    • The textbook diagram showed a detailed food web for the grassland ecosystem.
  • Trophic cascade (n): A series of effects caused by the addition or removal of top predators in a food cycle/web.
  • Ecosystem (n): The community of living organisms and their physical environment, within which the food cycle operates.
Synonyms
  • Food web: A system of interlocking and interdependent food chains.
  • Trophic network: A network of feeding (trophic) relationships among organisms.
Related Concepts
  • Food chain (n): A linear sequence of organisms through which nutrients and energy pass, starting with a producer and ending with a top predator or decomposer. A food cycle is composed of many interrelated food chains.
    • The simple food chain "grass → rabbit → fox" is part of a larger food cycle.
  • Energy flow (n): The movement of energy through an ecosystem via the food cycle.
  • Nutrient cycling (n): The movement and exchange of organic and inorganic matter back into the production of living matter, often facilitated by decomposers in the food cycle.
