Investigation 1 & 2
Abiotic - nonliving
Who were the producers in Mono Lake?
What is an autotroph?
an organism that makes its own food (producer)
The process by which toxin accumulates in bodies of predators, what am I?
bioaccumulation
the theoretical unlimited growth of a population over time
What type of study was Jane Goodall's study with the chimpanzees?
observational
What is Mono Lake known for?
The extreme salt concentration
A unit used to measure heat energy, what am I?
calorie
What are the four types of energy use?
Maintenance, growth and reproduction, movement, waste
Any biotic and abiotic component of the ecosystem that controls the size of a population, what am I?
limiting factor
What is the relationship between ecosystems and biomes?
ecosystems are a part of biomes
What is the decomposer at Mono Lake?
Halobacteria
How is biomass created?
By producers which use photosynthesis to grow and increase biomass.
What is the role of a decomposer?
Break down dead organic material and put nutrients back into the ground
What are some biotic and abiotic limiting factors?
(2 of each)
Abiotic: lack of space, weather, water, fire, climate change
Biotic: predators, injury, old age, lack of food/starvation
What is the difference between observation and inference?
Observation is something you can see using the 5 senses while an inference is an assumption based off of experiences
What are the different biotic and abiotic components of the Mono Lake ecosystem? (2 of each)
Biotic: birds, flies, shrimp, algae
Abiotic: water, salt, rocks, temperature
What are the three key elements producers need to grow and increase biomass?
Water, light, CO2
With trophic levels and the levels of the food web, how much of each level should be represented? (few, a lot, some)
a lot of producers
some primary consumers
few secondary/tertiary consumer
What are the important ideas/questions to know when trying to figure out reproductive potential of something? (Give 2)
How long does the organism live?
What is the ratio of males to females?
How many eggs/babies does the female have in her lifetime?
Put these in the order from smallest to largest (biome, population, individual, ecosystem, community).
Individual -> population -> community -> ecosystem -> biome
Name at least 4 of the 6 secondary consumers at Mono Lake. (Bonus points for the extra 2)
Red-necked phalarope, Wilson's phalarope, Eared grebe, California gull, Caspian tern, Snowy Plover
Why is aerobic cellular respiration important?
It converts sugars into usable into energy that all organisms need.
What is the 10% rule?
10% of the biomass moves up to the next trophic level for that organism to use as energy
Based on the graphs from the algae and brine shrimp experiments what were the additional abiotic and biotic limiting factors that limit their population size at Mono Lake? (Give 2 abiotic and biotic factors for both shrimp and algae)
Algae:
Abiotic: CO2, nutrients, space
Biotic: predators, diseases
Brine Shrimp:
Abiotic: space, water quality
Biotic: food, predators, diseases
