EVERYDAY SCIENCE

Detailed explanation-1: -Primary consumers are herbivores. Herbivores eat plants, algae, and other producers. They are at the second trophic level. In a grassland ecosystem, deer, mice, and even elephants are herbivores.

Detailed explanation-2: -The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain.

Detailed explanation-3: -Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers. Animals that eat only plants are called herbivores (or primary consumers).

Detailed explanation-4: -Some examples of primary consumers are deer, cow, rabbit, elephant, and zebra.

Detailed explanation-5: -Producers or autotrophs (which means “self-nourishment”) make their own energy by means of photosynthesis or chemosynthesis. In other words, they don’t need to feed on other organisms. Create organic molecules from water, carbon dioxide, minerals, and sunlight.
