Study Notes
Food Chain and Web Basics
- A food chain is a series of organisms that eat other organisms, with each level being consumed by the next level, forming a linear sequence.
- A food web is a more complex network of food chains that are interconnected, showing multiple paths of energy flow.
Energy Source in Food Chain/Webs
- The primary source of energy in a food chain or web is the sun, which is absorbed by producers (plants and algae) through photosynthesis.
Purpose of Creating a Food Web
- The purpose of creating a food web is to illustrate the complex relationships between organisms in an ecosystem, showing how energy and nutrients are transferred from one level to the next.
- Food webs help to identify the key species, their roles, and the potential impacts of changes in the ecosystem.
