What term is used to describe pathways for matter and energy in an ecosystem?

• A. Food Chain
• B. Energy Cycle
• C. Nutrient Pathway
• D. Habitat Network

Answer: (A)

The term that accurately describes pathways for matter and energy in an ecosystem is the food chain. A food chain outlines the linear sequence of organisms through which energy and nutrients flow as one organism consumes another. It begins with primary producers, such as plants, which convert solar energy into chemical energy through photosynthesis. This energy is then transferred to primary consumers (herbivores) that eat the plants, followed by secondary consumers (carnivores) that eat the herbivores, and so on. Each link in the food chain represents a step in the transfer of energy and matter, emphasizing the interconnected relationships where energy and nutrients are cycled through living organisms. Other terms presented do not encapsulate the concept as accurately. An energy cycle generally refers to broader processes, including how energy flows through an ecosystem, but it is not specific to the step-by-step transfer represented in a food chain. Nutrient pathway, while relevant to the flow of nutrients, does not comprehensively cover the entire ecosystem dynamics as it pertains to energy transfer. Habitat network falls into describing spatial arrangements and relationships within environments rather than the flow of energy and matter. Hence, the food chain is the most precise term for this process in ecological context.
