Types of Organisms and Food Webs

Types of Organisms 3 Groups of Organisms: Producers Consumers Decomposers Description Use energy from sun to make own food through photosynthesis Examples Flowers Trees Grass Need to eat other organisms for energy Humans Dogs Snake Hummingbird Break down dead organisms and returns nutrients to soil Mushrooms/Fungi Bacteria Worms Some bugs

Types of Description Examples Types of Consumers: Herbivores/ primary consumers Carnivores/ secondary consumer Eat only plants Giraffe Squirrel Cow Elk Eat only meat/ other animals “carne”= meat Omnivores Eat both animals & plants “omni”= all Scavengers Eat dead or injured animals Lion Tiger Shark Bear Pig Human Cockroach Vulture Raccoon

Practice…Just for fun. Grasshopper Frog Snake Just write the food chain w/ ARROWS and answer #2 in complete sentence!! Hawk

Description Examples Key Terms Types of Consumers Food Chain Food Web Energy Pyramid Trophic Levels A SIMPLE diagram showing flow of energy from ONE organism to another Interconnected food chains; Complex diagram showing feeding relationships A triangular diagram showing an ecosystem’s LOSS of energy The levels found on an energy pyramid or within food webs

Food Chain Wait a second… how do producers get their energy? Notice how it is linear… Food chains are very simple!

Energy Pyramid 10% Based on the data shown here…what PERCENTAGE of energy moves up the trophic levels?

Items to Practice : 1. After one species disappears, the other species in the ecosystem a. b. c. d. Die Benefit ARE affected Are NOT affected 2. Removing top predators from a food web is always beneficial to the other species. a. True b. False

Define in notes : 1. What is the difference between Autotrophs and Heterotrophs? Autotrophs make their own food (plants/producers) and Heterotrophs must find their food (consumers).

Practice in notes : Carnivore Omnivore Carnivore s r e. Herbivore um Carnivore s n o C Herbivore P P 1. Tell me who are the producers and who are the consumers. EX: producers- _______ consumers- _____ 2. For each consumer, tell me what type of consumer. EX: bass- carnivore

In which direction does the energy flow through the trophic levels? What percentage is passed on? Does it increase or decrease at each level?
