100
Means non-living
Abiotic
100
When one organism is harmed and the other benefits.
Parasitism
100
What does the arrow represent in a food chain?
Flow of energy
100
Which two processes absorb carbon?
Photosynthesis & Carbon Sink
100
What is a pioneer species?
The first species to colonize an area.
200
Another term for producer. Meaning an organism that can produce its own energy/food.
Autotroph
200
When both organisms benefit.
Mutualism
200
What is the ultimate source of energy?
The sun
200
What happens to the amount of carbon in the atmosphere when you cut down trees.
It increases.
200
What is a climax community?
Final stage of succession. Where biodiversity is stable.
300
What is a keystone species?
Species if remove from the ecosystem would cause it to fall apart. Maintains stability in the ecosystem.
300
When one organism benefits and the other is unharmed.
Commensalism
300
How much energy is transferred between each tropic level?
10%
300
Why does too much carbon in the atmosphere increase global temperature?
Carbon is a green house gas and traps the heat in the atmosphere.
300
What are 2 differences between primary and secondary succession?
Primary starts with bare rock while secondary starts with soil.
Primary takes longer, while secondary is faster.
400
What is a density independent limiting factor?
A factors that limits a populations growth regardless of size.
400
Lions feeding on gazelles is an example of which symbiotic relationship?
Predation
400
How much energy would the eagle have if the grass has 100,000 kJ of energy?
Grass-> grasshopper-> snake--> eagle
100 kJ
400
What is combustion?
The process of burning something. This process always releases carbon.
400
How do the pioneer species alter their environment in primary succession?
They break down rock into soil when they decompose.
500
This is a factor that limits a populations growth based on the density (size) of the population.
Density dependent limiting growth factor.
500
Explain how parasitism is a density dependent limiting factor.
Parasites spread disease which is a density dependent limiting factor because it spreads faster in larger populations.
500
Which organism is most likely the keystone species in this food web?
The eagle because it is the top predator and controls the population size of several of the organisms in the food web.
500
What is the role of decomposers in the carbon cycle?
Decomposers break down dead material and return carbon to the atmosphere as well as the soil to later turn into fossil fuels.
500
Which type of succession is pictured below? Explain how you know.
Primary because it starts with bare rock and takes hundreds of years to return to a climax community.
