This is a quick review of the 4th grade SPI- Recognize the impact of predation and competition on a ecosystem. It covers the following vocabulary words; ecosystem, predator, prey, resources, compete, and survive. It goes along with Lesson 5 of the TCAP Science Coach for 4th grade. There is a slide for each vocabulary word and some practice questions after. Can be used with any study of predator and prey. Could also be used to introduct materials.
