Types of Interactions
What type of interaction is it called when both organisms benefit?
Mutualism
What happens to the water vapor as it goes through condensation?
What type of succession is the growth of plants again, starting with soil and possibly some vegetation?
Secondary succession
What is a negative impact of deforestation?
Habitat loss for organisms that live there
List 3 examples of abiotic factors
Weather
Temperature
Rocks
Water
Sunlight
Define interspecific competition
Members of different species competing for resources
What is the thing that drives the water cycle?
The sun
List the order in which energy moves through the ecosystem (think about trophic levels).
Sun -> Producers -> Consumers -> Decomposers
What gas is put into the air as a result of using fossil fuels?
Carbon dioxide
List the resources every organism needs to survive
Food
Water
Space
What type of interaction is it when one organism benefits while the other is not affected?
Commensalism
What is the substance called that is in the atmosphere due to the carbon cycle?
Greenhouse gasses
When limited resources are available, what would happen to the organisms in that ecosystem?
Not all organisms can survive and reproduce in that ecosystem.
How do greenhouse gasses impact an ecosystem?
They add carbon dioxide to the atmosphere.
How is nitrogen returned to the soil?
Through animal waste and dead and decaying organisms
Why do some species become invasive while others do not?
Some do not negatively impact the native populations while others do
What processes moves carbon through the atmosphere?
Photosynthesis and cellular respiration
List 3 characteristics of invasive species.
Wide variety of diet
Few to no predators
Can survive in many climates
Decreases population of native species
Reproduces quickly
List some ways that humans directly impact ecosystems.
Hunting
Fishing
Introducing non-native organisms
Cutting down trees
Driving cars (emissions)
Littering
They act as a barrier before the storm surge or flood gets to the land.
Give a claim about maximum predator and prey relationships.
Predator and prey populations both rise and fall but are staggered in time.
What does photosynthesis do?
Uses sunlight to turn carbon dioxide and water into sugars and oxygen.
What is an effect fertilizers have on ecosystems?
The runoff of fertilizer goes into water and causes algae blooms and results in many fish dying
How do humas impact biodiversity?
Humans cause many different ecosystem changes which cause the numbers of species to be negatively impacted, throwing the ecosystems out of balance
What does cellular respiration help animals (and humans) do?
Break down food to be able to use it as energy
