What is an organism?
DOUBLE JEOPARDY: An organism that eats plants
What is an herbivore or primary consumer?

This gas, which plants use during photosynthesis, is a major component of the carbon cycle. What is it called?
carbon dioxide
Why do animals need nitrogen?
For protein
You are in a dark room with a box of matches. On a table are a candle, an oil lamp, and a log of firewood. What do you light first?
The match! Can’t light any of those things without a lit match.
DOUBLE JEOPARDY: Identify a community in this ecosystem
What are the polar bears, Arctic fox, seal, and starfish?
The species with the smallest population
What is the hawk population?
Mosses, Ferns, and lichens
What are examples of pioneer organisms?
Letter A in this picture.
What is oxygen?
the process of converting atmospheric N2 gas into ammonium (NH4+) through the bacteria found on leguminous plants
nitrogen fixation
I have 13 hearts, but no lungs or stomach. What am I?
A deck of cards.
Temperature, pH, Humidity, water in an environment
What are abiotic factors?
the rule that a certain percentage of energy is passed from one trophic level to the next through consumption
What is the 10% rule?
DOUBLE JEOPARDY: What is climax community?
the final stage of succession
The way primary producers provide carbon to primary consumers
What is feeding?
the geological process of that moves rocks from ocean into the land
uplift
What has a head, a tail, but no body?
coin
A population (define)
What are multiple individuals of the same species living together?
A food chain in this food web
What is grass, grasshopper, lizard, hawk, bacteria in that order? (answers can vary)
An example of secondary succession
wildfire, deforestation, hurricane, farming
DOUBLE JEOPARDY: a method humans contribute excess carbon to the atmosphere
combustion (burning of fossil fuel; transportation)
the physical and chemical breakdown of rocks that leads to the release of phosphate ions
weathering
An electric train is headed east. Where does the smoke go?
Electric trains don’t produce any smoke!
This level of ecological organization includes all the different communities within a specific area, interacting with each other and their environment, as well as the physical components such as soil, water, and air. What is this level called?
ecosystem
this type of organism can occupy multiple trophic levels by feeding on both primary producers and other consumers. What is it called?
omnivore
What is one function of pioneer species?
Fix Nitrogen
Break down rock
Add organic material to soil
What is photosynthesis and oceans dissolving carbon dioxide from the air?
DOUBLE JEOPARDY: this process involves decomposers breaking down organic nitrogen from dead organisms and waste products into ammonia(NH4)
ammonification
I have keys but open no locks. I have space but no room. You can enter but not go outside. What am I?
keyboard
This biome is known for its high rainfall and warm temperatures, supporting a wide variety of plant and animal life.
What is a rainforest?
The energy available for the hawks when 23,000 kcal is available at primary producer level
What is 23 kcal of energy available?
Sometimes, an ecosystem can recover after a natural disaster, but human activities can cause permanent damage. When a new species is brought into an area and takes over, harming native species and stopping succession, it is called this.
What is an invasive species?
this process occurs when dead organic matter is broken down by microorganisms
decomposition
What is assimilation?
the uptake of nitrates/phosphates from the soil through the roots of plants
What is seen in the middle of March and April that can’t be seen at the beginning or end of either month?
The letter “R.”
