Final answer:
The name given to the natural progression, or order, through which organisms find necessary food sources is food chain. A food chain is a linear diagram that shows the transfer of energy from one organism to another in an ecosystem. A food web is a more complex diagram that shows all possible feeding relationships among organisms in an ecosystem.
Step-by-step explanation:
The name given to the natural progression, or order, through which organisms find necessary food sources is food chain. A food chain is a linear diagram that shows the transfer of energy from one organism to another, as each organism consumes and is consumed by other organisms in an ecosystem.
For example, in a simple food chain, grass is eaten by a grasshopper, which is then eaten by a bird, and the bird may be eaten by a larger predator. This sequence represents the flow of energy and nutrients through the ecosystem.
In contrast, a food web is a more complex diagram that shows all possible feeding relationships among organisms in an ecosystem, including multiple pathways for energy flow.
