`ECOLOGY REVIEW #2 I. Define each of the following terms… A. Producer  – an organism that is capable of making its own food (plants  and some protists, some bacteria) by going through photosynthesis or  chemosynthesis; also called an autotroph B. Consumer  –an organism that must eat to get food/energy; also called a  heterotroph C. Herbivore  – an organism (type of consumer) that eats producers   (producers are: plants and some protists, some bacteria) D. Carnivore  –an (type of consumer) organism that eats other consumers  (meat-eater) E. Omnivore  – an organism (a type of consumer) that eats both producers  and consumers F. Scavenger  – an organisms that eats dead things G. Decomposer  – an organisms that breaks down dead things and returns  the nutrients to the soil/air/water II. Construct a food chain using the following organisms: rabbit, fox, grass, lion

Above shows the same food chain, yet it shows that everything is being decomposer!!! Note the direction of the arrows!!! III. Energy Pyramid (using the organisms from question IV – rabbit, fox, grass, lion – NO DECOMPOSERS). Rabbit Fox Lion Grass TL 1 Producer TL 2 Primary Consumer Herbivore TL 3 Secondary Consumer Carnivore TL 4 Tertiary Consumer Carnivore Rabbit Fox Lion Grass TL 1 Producer TL 2 Primary Consumer Herbivore TL 3 Secondary Consumer Carnivore TL 4 Tertiary Consumer Carnivore Bacteria Decomposers Fungi Bacteria Decomposers

The 10% Rule:  10% of energy moves onto the next level and 90% is used (for life  functions) or lost (as heat) to the environment. MATH QUESTIONS: If the grass had a biomass of 5,000 kg, identify the biomass available to the lion. *** Going up the pyramid, the number should get smaller – divide by 10 or move  the decimal 1 place to the left If the fox needs a biomass of 3.4g, identify the biomass of grass that must be available for the fox to survive.
