Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which of the following would get its energy from a primary consumer, and when eaten, transfers the energy to a top predator?

A	The Sun
B	A producer
C	A carnivore
D	A herbivore

Explanation:

Detailed explanation-1: -The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.

Detailed explanation-2: -The primary producers are autotrophs and are most often photosynthetic organisms such as plants, algae, or cyanobacteria. The organisms that eat the primary producers are called primary consumers. Primary consumers are usually herbivores, plant-eaters, though they may be algae eaters or bacteria eaters.

Detailed explanation-3: -Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
