Key Concepts Covered

➡️ Trophic levels – Organisms are classified into levels based on their feeding relationships in an ecosystem, starting with producers and moving upward through herbivores and predators.
➡️ Food webs and chains – Visual representations of feeding relationships that illustrate how energy is transferred through an ecosystem.
➡️ Producers and consumers – Organisms that produce energy from sunlight versus those that consume other organisms for energy.
➡️ Nutrient recycling and decomposers – The vital role decomposers play in breaking down organic matter and returning nutrients to the environment.
➡️ Trophic cascades – Ecological phenomena where changes at one trophic level impact multiple levels, influencing overall ecosystem stability.
