Food Web Dynamics and Roles

The video tutorial explores the concept of food webs, starting with the relationship between humans and mosquitoes. It explains the roles of producers like Sawgrass and periphyton, primary consumers such as shrimp and insects, and secondary consumers like the limpkin. The video also covers decomposers and the flow of energy within food webs, emphasizing the importance of understanding these relationships in ecosystems.

What is the primary relationship between humans and mosquitoes in the context of a food web?

• Mosquitoes are pests to humans.

• Humans provide food for mosquitoes.

• Humans and mosquitoes are decomposers.

• Mosquitoes and humans are both producers.

What process do producers like Sawgrass use to create their own energy?

• Decomposition

• Photosynthesis

• Respiration

• Fermentation

Which of the following is considered a producer in a food web?

• Insects

• Periphyton

• Apple snail

• Limpkin

What is the role of primary consumers in a food web?

• They produce their own energy.

• They eat producers.

• They decompose dead organisms.

• They eat secondary consumers.

Which organism is an example of a primary consumer?

• Sawgrass

• Fungus

• Limpkin

• Shrimp grass

What distinguishes a secondary consumer in a food web?

• They produce their own food.

• They decompose organic matter.

• They eat producers directly.

• They eat primary consumers.

Which of the following is a secondary consumer?

• Sawgrass

• Periphyton

• Limpkin

• Apple snail

What is the primary function of decomposers in a food web?

• They produce energy from sunlight.

• They consume primary consumers.

• They break down dead organisms.

• They provide food for producers.

Which of the following could be a decomposer in a food web?

• Limpkin

• Fungus

• Shrimp grass

• Apple snail

In a food web, what does the direction of the arrow indicate?

• The direction of energy flow

• The size of the organism

• The speed of energy transfer

• The lifespan of the organism
