Biomagnification “Taste that, you higher tropic levels!!”
+ Food and Competitors • Agriculture and our food • Create small food chains plants → people • “Our Food” or “Our Food” X • Insects need to be kept in check • Disease • Interspecific competition
Pests Use of Pesticides • To keep the “food chain” from becoming a “food web” we can use pesticides to deal with pests People Plants
Downside of Pesticides • Pesticides do their job, but they will travel along through the food chain likeenergy will. • Unlike energy, it is not lost between each tropic level. • In fact Pesticides remain and magnify as they move through the food chain
Energy Tropic Level 4 Eagle Because energy is lost between each tropic level organisms from higher levels are forced to consume many organisms from the level below to keep energy levels up. Tropic Level 3 Trout Tropic Level 2 Itty Bitty Fish Tropic Level 1 Water plant
Energy Maintained Number of Organisms eaten Tropic Level 4 Eagle Trout Tropic Level 3 Trout Itty Bitty Fish Tropic Level 2 Itty Bitty Fish Water Plant Tropic Level 1 Water plant
As each consumer eats an organism it also takes in all of it toxins
Toxins Number of Organisms eaten Tropic Level 4 Tropic Level 3 Tropic Level 2 Itty Bitty Fish Tropic Level 1 Water plant
