In the context of ecological roles, are bears considered producers or consumers?

• A. Producers
• B. Consumers
• C. Autotrophs
• D. Decomposers

Answer: (B)

Verified step by step guidance

1. Understand the definitions of ecological roles: Producers are organisms that create their own food through processes like photosynthesis (e.g., plants and algae). Consumers are organisms that obtain energy by eating other organisms. Autotrophs are producers, while decomposers break down dead organic matter.
2. Identify the diet and energy acquisition method of bears: Bears do not produce their own food through photosynthesis or chemosynthesis, so they are not producers or autotrophs.
3. Recognize that bears consume other organisms for energy: Bears eat plants, fruits, and animals, which classifies them as consumers.
4. Differentiate bears from decomposers: Decomposers, such as fungi and bacteria, break down dead organic matter into simpler substances. Bears do not perform this role.
5. Conclude that bears are consumers based on their ecological role of obtaining energy by consuming other organisms.
