WebOptimal foraging theory helps biologist to understand the factors determining a consumer’s operation range of food types. Predators have been described into two categories based on its foraging strategies: searching (active or ‘widely foraging’) and sit-and-wait or ambush. A searching predator moves throughout its habitat and find its prey. can antibiotic cause high blood pressure
