Topic 1:What’s the Matter with Energy?!
This type of organism can make its own food using sunlight.
What is a producer?
This term describes the number of individuals in a specific area.
What is population density?
This is the term for the gradual change of ecosystems over time.
What is ecological succession?
The total variety of life in an area.
What is biodiversity?
$100: This footprint measures the total impact a person or group has on the planet.
🦶 What is an ecological footprint?
This organism breaks down dead things and recycles matter.
What is a decomposer?
This kind of growth curve shows rapid population increase with unlimited resources.
What is exponential growth?
Succession that begins with bare rock and no soil.
What is primary succession?
This kind of diversity means many genes and traits within a species.
What is genetic diversity?
$200: These types of resources, like solar or wind, can be replenished quickly.
🌬️ What are renewable resources?
This type of energy transfer happens in a food chain or web.
What is from producers to consumers?
The maximum number of organisms an ecosystem can support.
What is carrying capacity?
The first organisms to colonize bare rock.
What are pioneer species?
This type of graph shows trophic levels and energy transfer.
What is an energy pyramid?
Human activities increase this gas, which traps heat in the atmosphere.
🌡️ What is carbon dioxide (CO₂)?
Only this percentage of energy transfers to the next level in a food chain.
What is 10%?
A factor like disease or competition, which increases in effect as population grows.
What is a density-dependent limiting factor?
Succession that happens after a forest fire or flood.
What is secondary succession?
High biodiversity makes an ecosystem more this.
💪 What is resilient?
$400: This process releases carbon back into the atmosphere by burning fossil fuels.
🔥 What is combustion?
This cycle moves carbon between the atmosphere, organisms, and fossil fuels.
What is the carbon cycle?
Rainfall, fires, and human dams are examples of this kind of limiting factor.
What is a density-independent limiting factor?
The final stable ecosystem that forms after succession.
What is a climax community?
This kind of diversity means many different types of ecosystems.
🏞️ What is ecosystem diversity?
Too much algae growth from fertilizers leads to this oxygen-depleting phenomenon.
💀 What is eutrophication?
