This is a PowerPoint that has excellent pictures of different types of species that live in aquatic biomes--primarily the oceans and sloughs.
This PowerPoint goes through the food web and has a picture of the ocean food energy pyramid. Students will be able to visualize the idea of food webs and what types of species are involved in this type of biome. It also goes through different types of topographies for these biomes--sloughs, estuaries, atolls, reefs, hydrothermal vents, etc.
This PowerPoint would be great for both a beginning biology course during the ecosystem unit and for an AP Environmental Science course.
Let me know what you think and have fun presenting!
