NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: Some consumers get their energy by eating producers. These are called primary consumers. Other consumers, called secondary consumers, get their energy by eating primary consumers.

Detailed explanation-2: -Secondary consumers are organisms that receive their energy from primary consumers. Most secondary consumers are carnivores, meaning they survive by eating animal tissues.

Detailed explanation-3: -Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both.

Detailed explanation-4: -Secondary consumers receive 10% of the energy available at the primary consumer level (1% of the original energy). Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy).

Detailed explanation-5: -As you can see, the primary consumer does not have all of the energy from the plant available to it. Only the green stored energy is available to the consumer. Thus, a primary consumer is going to be more efficient than a secondary consumer.
