However, additional effects from interactions between species (e.g., predator-prey interactions) may also occur in natural systems. Predator Prey Interactions Worksheets & Teaching Resources | TpT Even fundamental information on the circumstances that elicit particular antipredator behaviors remains under-investigated.
