1 13) FOOD CHAIN: a model used to show energy from food passes from one organism to another. For example: sunlight => grass => grasshopper => frog => snake => hawk

2 14) FOOD WEB: A model used to describe a series of overlapping food chains.

3 15) PRODUCER: (autotroph) An organism that is able to produce its own food through photosynthesis. Examples: all plants, some protists (euglena, algae), cyanobacteria;

4 16) CONSUMERS: (heterotrophs) Organism that cannot create energyrich molecules but obtains its food by eating other organisms.

7 4) 5) Soil, light, water, temperature 6) 7) Most soils are made up of sand, clay, and humus. 8)

8 9) A population is all of the individuals of one species living in the same area at the same time. 10) 11) An ecosystem is made up of communities and the abiotic factors that affect them.

9 An abiotic factor is caused by or consists of something that is nonliving.

11 OF ICE AND FIRE 1) What is the one abiotic factor that is most important in the Mono Lake ecosystem? 2) What two organisms are most important in the Mono Lake ecosystem 3) What is the major issue concerning the well-being of the Mono Lake ecosystem? 4) List two examples of biotic interactions that take place in the Mono lake ecosystem:

12 Mono Lake is the oldest lake in the US (>760,000 years)

17 1) Which is saltier, the ocean or Mono Lake? 2) Mono Lake is a unique and ancient. It is at least years old, making it the oldest lake in the. 3) Even though it looks barren, Mono Lake is actually one of the most on the continent. Below the water s surface a huge population of is the base of a. Massive populations of and brine feed on the algae. These crustaceans and insects in turn provide nourishment for populations of that come to Mono Lake. 1) Mono Lake is far saltier than the ocean. 2) ecosystem, 760,000, United States 3) Productive ecosystems, algae, food web, brine shrimp, flies, birds.

18 OF ICE AND FIRE 1) What is the one abiotic factor that is most important in the Mono Lake ecosystem? 2) What two organisms are most important in the Mono Lake ecosystem 3) What is the major issue concerning the well-being of the Mono Lake ecosystem? 4) List two examples of biotic interactions that take place in the Mono lake ecosystem:

19 OF ICE AND FIRE 1) The one abiotic factor that is most important in the Mono Lake ecosystem is: Water level or salt concentration (Amount of water affects the salinity of the water) 2) The two organisms that are most important in the Mono Lake ecosystem are: Planktonic Algae and Benthic Algae (They are the only producers next most important: Brine shrimp and Brine flies) 3) The major issue concerning the well-being of the Mono Lake ecosystem is: The water level must be maintained for the brine shrimp and brine flies. (If the water level goes down the salt concentration rises)

20 OF ICE AND FIRE 3) The major issue concerning the well-being of the Mono Lake ecosystem is: The water level must be maintained for the brine shrimp and brine flies. (If the water level goes down the salt concentration goes up.) 4) Two examples of biotic interactions that take place in the Mono lake ecosystem are: Birds (gulls, plovers, phalaropes) eating brine shrimp and brine flies; Coyotes eating gull eggs and chicks;
