Without these organisms, a food web would not work. Typically they get their energy from the sun...
What are PRODUCERS?
100
Two different organisms provide a benefit to each other in this form of symbiosis...
What is MUTUALISM?
100
These are the basic materials available at the beginning of primary succession...
What are ROCKS / DIRT?
100
TRUE OR FALSE: Nitrogen is more useful when it is fixed to something.
TRUE
100
These 4 letters represent the 4 different nitrogen bases which are part of DNA nucleotides...
What is A,T,G,C?
200
These are usually the carnivores in an ecosystem and need several animals to prey on for energy...
What are TERTIARY (or quaternary) CONSUMERS?
200
Tree frogs use plants for protection. The plants are not affected by this interaction...
What is COMMENSALISM?
200
Moss and lichen are perfect examples of these species...
What are PIONEER SPECIES?
200
In ecosystems, carbon is usually found in this form. (Hint: think of air)
What is CARBON DIOXIDE?
200
🎵 DNA to RNA is _______________
🎵 RNA to Protein is _______________
What is TRANSCRIPTION and TRANSLATION?
300
If the Producers on an energy pyramid have 1000 J of energy available, then how many J would be available to the Secondary Consumers?
What is 10 J?

Mosquitos like to take "free samples" of blood on your camping trip. This causes itching and annoyance. Mosquitoes and humans are an example of this symbiotic relationship...
What is PARASITISM?
300
This is the term for the fully-developed ecosystem with all the producers and consumers in place...
What is a CLIMAX COMMUNITY?
300
Whereas many carbon reservoirs are either in the air or in organisms, much of the nitrogen is found here. (Hint: where do plants get nutrition from?)
What is the SOIL / GROUND?
300
This is the process by which populations that are well adapted to their environment get to survive and reproduce...
What is NATURAL SELECTION?
400
Once living things begin to die or decay, these microorganisms have the job of recycling their nutrients back into the ecosystem...
What are DECOMPOSERS?
400
This relationship is highlighted by a lack of food, habitats, or mates.
What is COMPETITION?
400
A field that had been untrimmed for decades finally gets mowed down, causing a disturbance in the community of insects / small animals that were already living there...
What is SECONDARY SUCCESSION?
400
These microorganisms are responsible for taking ammonia from living things and returning them into the ground...
What are DECOMPOSERS / BACTERIA?
400
A brown eyed male (Bb) marries a blue eyed female (bb). What is the percent chance of blue-eyed children?
What is 50%?

Identify the role of each organism in this food web.
Plant: producer
Butterfly, Caterpillar, Squirrel, Bird: primary consumer
Frog, Snake, Fox: secondary consumer
Eagle: tertiary consumer

Jim always does his part of the group project, but lets people copy his work. Sam never does his fair share, but insists on copying from another classmate and taking credit for it. Lisa gives her group partners Hot Cheetohs in exchange for help on the project. Ron does not care about the project getting done either way.
Using these 4 characters, describe parasitism, mutualism, and commensalism.
Jim + Sam = parasitism
Jim + Ron = commensalism
Jim + Lisa = mutualism

Explain the difference between primary and secondary succession using the following terms:
pioneer species, climax community, producers, consumers, natural disaster
(EXAMPLE): Primary succession begins with no living things, then pioneer species arrive to break down rocks into soil. With soil comes new producers, and then consumers, and eventually a climax community is built. In secondary succession the climax community is disturbed by a natural disaster (or human interaction) and must be rebuilt over time.

This is the name of the process by which carbon is cycled into their atmosphere.
(Hint: remember what was the "opposite" of photosynthesis?)
What is RESPIRATION?
500
Put the following terms in order from smallest to largest magnitude
Population, organism, cell, ecosystem, organ tissue, organ, community
Cell < Organ Tissue <Organ < Organism < Population < Community < Ecosystem
