Climate
How do oceans help control Earth's temperature?
The Ocean absorbs and stores heat. Water heats slowly, keeping temperatures more stable and moving heat around the planet
What is natural selection?
Organisms with favorable traits survive and reproduce. Favored traits are passed on and enable populations to evolve.
How do plants use carbon dioxide?
They need CO2 as a reactant for photosynthesis to occur. This is used in the process of plants making their own food.
Give one example of an environmental factor that affects health.
Polluted air or water
What is one way we can reduce waste?
recycling, reusing, or reducing
What is one effect of greenhouse gases?
Secondary succession differs from primary succession because it:
Begins after a natural disturbance (EX: Forrest fire, Tsunami)
Why is nitrogen important for plants?
Plants use nitrogen to make protein. it is a necessary component in building DNA and protein.
What is a renewable recourse? Give one example
A resource that can be replenished naturally. Example: Sunlight, Wind, Water
Why is the ozone important?
It protects Earth from harmful UV radiation
Why are fossil fuels considered limited resources?
they renew at a slow rate
What happens when a population exceeds it's carrying capacity?
The population will crash due to lower available resources and higher competition.
What is a major problem of over farming?
Soil erosion (over using the land removes vegetation and causes erosion overtime)
What is a nonrenewable resource? Provide an example.
A resource that cannot be replenished in our life time. EX Coal, Oil, Natural gas, Fossil fuels
Which factor is most important when evaluating the long-term sustainability of an energy resource?
Rate of renewal
An increase in atmospheric CO₂ primarily affects which process in the carbon cycle?
Photosynthesis and Ocean absorption
Which relationship benefits one species while harming the other?
Parasitism
Which practice best supports sustainable land use?
crop rotation
Which indicator best reflects the relationship between population size and environmental stress?
Ecological Footprint
What abiotic factor most directly limits photosynthesis in aquatic systems?
light availability
Climate change can cause ecosystems to...
Shift biome boundaries
Why are ecosystems with low biodiversity more vulnerable to collapse?
reduced resilience to change (EX: disease outbreaks could be catastrophic)
Which human activity most directly alters the nitrogen cycle by increasing bioavailable nitrogen in ecosystems?
Synthetic fertilizer use
True or false: Consuming less meat products, has the power to lower greenhouse gas emissions.
Which factor most directly accelerates modern extinction rates?
Human land use
