Limiting Factors
100
Two species with the same niche cannot coexist in the same habitat for long without one either becoming extinct, or being driven out due to competition.
What is competitive exclusion principle? (Gause's Law)
100
The type of population growth that is shown above.
What is exponential growth?
100
Relationship where members of one species consume members of another species.
What is predation?
100
The amount of energy or biomass that is transferred from one trophic level to the next.
What is the 10% rule?
100
Relationship where both organisms benefit.
What is mutualism?
100
Limiting factors that are typically abiotic.
What is density independent limiting factors?
200
Members of the same species trying to obtain the same resources.
What is intraspecific competition?
200
The type of population growth that is shown above.
What is logistic growth?
200
Why do predators have to consume other members of other species?
Energy & biomass (can't produce themselves)
200
The original source of energy in all ecosystems.
What is sunlight?
200
Relationship where one organism benefits while the other is neither helped or harmed.
What is commensalism?
200
Limiting factors that are typically biotic.
What are density dependent limiting factors?
300
Members of different species trying to obtain the same resources.
What is interspecific competition?
300
The graph above is representing this relationship.
What is competition?
300
Things that help predators catch prey.
What are structural adaptations?
300
If your producer has 13000 kcals of energy, the amount available to your tertiary consumer.
What is 13 kcals?
300
Relationship where one organism benefits while the other is harmed.
What is parasitism?
300
The maximum number of organisms an ecosystem can support.
What is carrying capacity?
400
The type of competition being represented in the picture.
What is interspecific competition?
400
Draw a trophic level pyramid and place these organisms into their correct trophic levels.
Producers: carrots, grasses, grains
Primary consumers: rabbits, mice, grasshoppers
Secondary consumers: birds, owls
Tertiary consumers: foxes
400
Why are there significantly less predators than there are prey?
10% rule, not as much energy and biomass available at the top of the pyramid.
400
The grasshopper has 101 kg of biomass. Fill in the rest of the pyramid (top to bottom).
Grass (producer): 1010 kg
Grasshopper (pc): 101 kg
Bird (sc): 10.1 kg
Eagle (tc): 1.01 kg
400
_______ succession is when an ecosystem starts on bare rock; ________ succession is when an ecosystem starts with soil.
1st - Primary
2nd - Secondary
400
This is representing this type of limiting factor.
What is a density independent limiting factor?
500
The type of competition being represented in this picture.
What is intraspecific competition?
500
The graph above is representing this type of relationship.
What is predator/prey?
500
Why do predators increase after prey decreases?
Predators increase due to a lag of prey population decreasing.
500
Your secondary consumer has 45 kcals of energy available to them. Fill in the rest of the levels from producer to quaternary consumer.
Producer: 4500 kcals
Primary Consumer: 450 kcals
Secondary Consumer: 45 kcals
Tertiary Consumer: 4.5 kcals
Quaternary Consumer: 0.45 kcals
500
