I WONDER - What Is A Trophic Level?

The video explains the concept of trophic levels in food webs, categorizing organisms into producers, consumers, and decomposers. Producers, or autotrophs, create their own food through photosynthesis. Consumers, unable to produce their own food, rely on eating plants or other animals. Decomposers break down non-living organic matter, recycling nutrients back into the ecosystem.

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

• To provide shelter for animals

• To create their own food

• To decompose organic matter

• To consume other organisms

Which process do most autotrophs use to produce their food?

• Respiration

• Digestion

• Photosynthesis

• Fermentation

What distinguishes consumers from producers in a food web?

• Consumers are always at the top of the food chain

• Consumers decompose organic matter

• Consumers rely on other organisms for food

• Consumers can produce their own food

Which of the following is true about decomposers?

• They produce their own food

• They consume living plants

• They feed on non-living organic matter

• They are primary consumers

What role do decomposers play in the ecosystem?

• They compete with consumers for food

• They break down dead organisms

• They are the main source of food for producers

• They create energy from sunlight
