Adaptations
What type of organism would survive by feeding on the blood of another organism? (carnivore, insectivore, parasite, predator)
parasite
Name one way carbon/CO2 is naturally removed from the atmosphere
plants/photosynthesis
If the death rate is higher than the birth rate, will the population increase or decrease?
decrease
List the order of biomass (consumers, producers, decomposers)
producers -> consumers -> decomposers
Photosynthesis is a process that turns light energy into chemical energy. What form is chemical energy?
ATP
In nature, which type of behavior causes animals to display aggressive displays and sounds? (imprinting, territoriality, conditioning, habituation)
territoriality
Burning of fossil fuels contributes to the greenhouse effect. Does the greenhouse effect increase or decrease atmospheric temperatures?
Increases
List 3 biotic limiting factors
predators, competition, food, pathogens/disease, etc.
Order the following in an energy pyramid: Secondary consumers, primary consumers, producers, tertiary consumers
producers -> primary consumers -> secondary consumers -> tertiary consumers
What is the difference between biotic vs. abiotic?
living vs. nonliving
An annoying ringing noise in the classroom is bothering my students, but after a long period of time, it no longer bothers them. What kind of adaptation have these students experienced? (Innate behavior, Learned Behavior, Reproductive, Structural)
Habituation/ learned behavior
Does nitrogen fixation create nitrates (useful nitrogen) or atmospheric nitrogen?
nitrates/useful nitrogen
What term describes the max. number of organisms an environment can support?
Carrying Capacity (K)
What kind of symbiotic relationship occurs when tree frogs use plants as protection and do not harm the plant? (mutualistism, commensalism, parasitism, predation)
Commensalism
Insects get nectar from flowers and also transfer the pollen to other flowers. What type of symbiotic relationship is occurring? (commensalism, mutualism, parasitism)
Mutualism
What do the words chemotaxis and phototaxis mean? (hint: what does taxis mean? chemo? photo?)
movement response to chemicals and movement response to light
If large scale deforestation affected the carbon cycle, would carbon increase or decrease? What about oxygen?
Carbon increases, Oxygen decreases
What does a density-dependent limiting factor depend on?
population size
Does energy increase or decrease as you go to a higher trophic level?
Decrease b/c some of the energy is used during the life processes of organisms
List one density dependent and one density independent limiting factor
density dependent: predation, disease, competition, food, symbiotic relationships/parasites
density independent: water, natural disaster, weather, sunlight, pollution, fire
What is the difference between internal and external fertilization?
internal is inside the organism's body, external is when gametes are released into environment
What human action will cause a negative impact on the carbon cycle by increasing carbon in the atmosphere?
deforestation, combustion/burning of fossil fuels
If there are unlimited resources and space, will a population grow exponentially or logarithmically?
Exponentially
If the producers in an ecosystem have 100,000 kJ of energy, how much energy would the primary consumers have? (hint: use the 10% rule)
10,000 kJ of energy
In 1995, a population of hares reach the highest number of organisms at 1,300 hares, followed by a small decline to 1,000 hares due to fires. The population begins to stabilize around 1,150 hares over many years. What is the carrying capacity?
1,150 hares
