Begin with an engaging question: 'What do you think would happen if all the plants in a forest disappeared?' This will spark curiosity about the role of consumers in ecosystems.

Introduce the concept of consumers with a brief overview of herbivores, carnivores, and omnivores, setting the stage for deeper exploration.

Explain the energy flow in ecosystems, focusing on how consumers obtain energy from producers and other consumers.

Discuss the classification of consumers into herbivores, carnivores, and omnivores, using examples like giraffes, lions, and bears.

Facilitate a discussion on the dietary habits of specific herbivores, carnivores, and omnivores, and how these affect their role in the ecosystem.

Explore the diversity of herbivorous organisms in different environments, such as land and ocean ecosystems.

Have students create a simple food chain model using craft materials to visualize the flow of energy from producers to consumers.

Conduct a classification activity where students sort pictures of animals into herbivores, carnivores, and omnivores.

Assign students to research and present on a specific consumer, detailing its diet and role in its ecosystem.

Use a quick quiz to assess students' understanding of the roles of herbivores, carnivores, and omnivores in ecosystems.

Encourage students to reflect on how the absence of a specific consumer might affect an ecosystem.

Provide a comprehensive assessment pack that includes activities like labeling food chains and identifying consumer roles.
