Ecosystem Roles and Energy Flow

The video tutorial covers the basics of ecosystems, focusing on the interactions between biotic and abiotic factors. It explains the roles of producers, consumers, and decomposers in the food chain. The types of consumers—herbivores, omnivores, and carnivores—are discussed, highlighting their dietary habits. The tutorial concludes with a summary and a preview of the next lesson, which will involve constructing food chains.

What are the two main types of factors in an ecosystem?

• Biotic and abiotic

• Producers and consumers

• Herbivores and carnivores

• Decomposers and omnivores

What is the primary source of energy for producers in a food chain?

• Water

• The Sun

• Soil

• Decomposers

Which process do producers use to make their own food?

• Decomposition

• Respiration

• Photosynthesis

• Fermentation

What is the main characteristic of consumers in a food chain?

• They only eat plants

• They must eat other organisms for energy

• They decompose dead matter

• They produce their own food

Which of the following is NOT a type of consumer?
