Evolution is a process by which the gene pool of an organism ______________ _______ ________
changes over time
The origin of all energy on Earth.
What is the sun?
The reactants AND products in photosynthesis.
What is...
Reactants: Sunlight + Carbon dioxide (6CO2) + Water (6H2O)
Products: Glucose (C6H12O6) + Oxygen (6O2)
The process by which producers get carbon.
What is through photosynthesis?
The most important organisms in the nitrogen cycle.
What are the bacteria?
Carrying capacity.
What is the maximum number of organisms that an ecosystem can sustain?
Similarities like elbows in the front limbs of mammals such as bats, penguins and alligators
What is are homologous structures
Of the following organisms found in the food web, which belongs to the trophic level with the highest amount of available energy?
What is the flagellates?
The reactants AND products of cellular respiration.
What is...
Reactants: Glucose (C6H12O6) + Oxygen (6O2)
Products: Carbon dioxide (6CO2) + Water (6H2O)
The process by which consumers release carbon back into the atmosphere.
What is through cellular respiration?
The where is most nitrogen stored? (i.e. The sphere where 78% nitrogen is found).
What is the atmosphere.
Limiting Factors.
Abiotic and biotic factors that affect the growth of a population.
Give the outgroup and two species closest related
Outgroup: Platypus
Common: Dogs and bats, Elephants and Tenrecs
The number of kcals of energy available to the third trophic level if the food chain begins with 20,000 kcals.
What is 200 kcals.
(20,000 x 0.1 x 0.1)
The organisms that perform photosynthesis.
(Producers, consumers, or both?)
What are the producers (plants/phytoplankton/autotrophs)?
What 5 carbon cycle steps did we see in our biobottles?
What are:
1. Photosynthesis
2. Respiration
3. feeding
4. Decomposition
5. Gas Exchange
The difference between how autotrophs (i.e. plants) and heterotrophs (i.e. animals) obtain nitrogen.
What is: Animals can't get their nitrogen from the environment. Needs to consume plants/other organisms
A population of bobcats lives in a mountain ecosystem. Which of the following are likely to be limiting factors for the bobcat population?
1. Cooperation between species.
2. Amount of prey.
3. Competition for shelter.
4. Spread of disease.
What is...
2. Amount of prey.
3. Competition for shelter.
4. Spread of disease.
Which two species are closest related?
Humans and Chimpanzee's
Where the 90% of energy that is not made available to organisms in the next trophic level goes.
What is to the environment as heat?
The organisms that perform cellular respiration.
(producers, consumers, or both?)
What are both (plants, animals, phytoplanktons)?
What human activity(s) has led to an increase in carbon in the atmosphere?
What is...
1. Burning fossil fuels.
2. Deforestation.
The effect that taking away plants such as sugar cane and grass would have this effect on the nitrogen cycle.
What is:
Less nitrogen being available to animals that eat producers.
The BIOTIC factor that affects the size of a population in an ecosystem.
a. Local geography
b. Number of predators present
c. Average yearly temperature
What is the number or predators present?
A population of bacteria is treated with hand sanitizer. Because of genetic variation in the population, what is a possible outcome?
a. The population will grow quickly.
b. All of the bacteria are already resistant.
c. The bacteria will get better at obtaining a food source.
d. Those bacteria that have a mutation that allows them to be resistant will survive to reproduce.
Those bacteria that have a mutation that allows them to be resistant will survive to reproduce.
The food chain with the most organisms in the following food web.
What is...
Plankton --> Krill --> Squid --> Penguin --> Seal
The relationship between photosynthesis and cellular respiration.
What is they supply one another with the reactants that they need to create the products that organisms need to survive.
Cycling of key matter!
Mutualism
The way that the law of conservation of matter applies to the carbon cycle.
What is the carbon atoms may change forms, but the amount of matter that is cycled never changes?
BONUS!!!
The macromolecules that require nitrogen.
OR Why do humans need nitrogen?
What are:
1. Proteins
2. Nucleic Acids
To grow and develop
Lupine plants growing in a certain national park provide food and shelter for a population of aphids. Scientists recently identified a fungal disease that is expected to reduce the number of lupine plants in the national park.
If there are fewer lupine trees, how will that affect the carrying capacity of the aphids, as well as the aphid population?
What is...
1. The carrying capacity of the aphids will decrease.
2. The population of aphids will decrease.
