🔬 What Students Will Learn
Through this resource, students will explore how energy enters ecosystems and why energy availability changes between trophic levels. Learners will investigate the role of producers and consumers, interpret patterns in energy transfer, and examine how biomass and available energy decrease as organisms move higher in a food chain.
Students will practice understanding and applying concepts such as:
• Energy flow through ecosystems
• The role of the Sun as the primary energy source
• Primary producers and photosynthesis
• Herbivores, carnivores, and omnivores
• Food chains and food webs
• Trophic levels
• Biomass distribution
• Energy pyramids
• Trophic efficiency
• Ecological relationships and ecosystem stability

🌎 Support Meaningful Science Learning
Energy transfer is one of the most important concepts in ecology. This resource helps students visualize how energy moves through living systems while understanding why each trophic level contains less available energy than the level below it. Students gain a stronger appreciation for ecosystem structure and the relationships between organisms.
By examining trophic efficiency and biomass patterns, learners develop a scientific explanation for why ecosystems generally contain fewer organisms at higher trophic levels. These foundational concepts support future learning in ecology, biodiversity, environmental science, and sustainability.
