INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants)

Contributing to the diverse life forms in Arthropoda are extremely diverse systems of feeding and digestion. Carnivores‚ herbivores‚ and parasites all exist within arthropods. The appendages at the mouth usually distinguish from arthropod to arthropod based on their diets. Spiders have a pair of fangs or chelicerae that deliver poison into their prey. Scorpions inject
