An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3]Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
Like all carnivorous plants, pitcher plants all grow in locations where the soil is too poor in minerals and/or too acidic for most plants to survive. Pitcher plants supplement available nutrients and minerals (which plants normally obtain through their roots) with the constituents of their insect prey.
Within an ecological food chain, consumers are categorized into primary consumers, secondary consumers, and tertiary consumers. [3] Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).
Carnivory in plants is a very specialized form of foliar feeding, and is an adaptation found in several plants that grow in nutrient-poor soil. Carnivorous traps were naturally selected to allow these organisms to compensate for the nutrient deficiencies of their harsh environments and compensate for the reduced photosynthetic benefit.

There are carnivorous plants as well as herbivores and carnivores that consume plants and animals, respectively. Due to the extremely low nutritional content of the soil in which they grow and extra nitrogen is needed by the plants, therefore carnivorous plants eat insects. By photosynthesis, these plants continue to receive energy from the sun ...
The Global Forum on Food Security and Nutrition suggests edible insects as a solution to the “rising costs of animal protein, food and feed insecurity, environmental pressures, population growth ...
While amphibians continued to feed on fish and insects, some reptiles began exploring two new food types, tetrapods (carnivory) and plants (herbivory). The entire dinosaur order ornithischia was composed of herbivorous dinosaurs. [14] Carnivory was a natural transition from insectivory for medium and large tetrapods, requiring minimal adaptation.
In this case, the pesky bugs, which are actually called weevils, infest the whole kernels and lay eggs in the wheat grains before it's been milled into flour, Quoc Le tells Delish.
