How do consumers obtain their energy in the process of cellular respiration?

• A. By breaking down organic molecules to release energy
• B. By synthesizing glucose from carbon dioxide and water
• C. By absorbing energy directly from the environment
• D. By converting sunlight into chemical energy

Answer: (A)

Verified step by step guidance

1. Understand the role of consumers in an ecosystem: Consumers are organisms that obtain energy by feeding on other organisms or organic matter, unlike producers that can synthesize their own food.
2. Recognize the process of cellular respiration: Cellular respiration is a metabolic process where cells convert biochemical energy from nutrients into adenosine triphosphate (ATP), and release waste products.
3. Identify the source of energy for consumers: Consumers obtain energy by breaking down organic molecules, such as carbohydrates, fats, and proteins, through cellular respiration.
4. Differentiate between cellular respiration and photosynthesis: Photosynthesis is the process by which producers, like plants, convert sunlight into chemical energy stored in glucose. Consumers do not perform photosynthesis.
5. Conclude how consumers obtain energy: Consumers rely on the breakdown of organic molecules during cellular respiration to release energy, rather than synthesizing glucose or absorbing energy directly from the environment.
