100
Give an example of a producer.
trees, grass, flowering plants, algae, etc.
100
What does the rat eat?
insects
100
What does the mouse eat?
grass
100
Where are producers found on an energy pyramid?
the bottom
100
What is the difference between a food chain and a food web?
A food chain shows one path of energy flow. A food web is many overlapping food chains.
200
What is the difference between an autotroph and a heterotroph?
Autotrophs make their own food. Heterotrophs consume other organisms.
200
What energy role always begins a food chain?
producer
200
Name all of the krill's predators. (must name all 4)
seal, squid, seagull, blue whale
200
What % of energy is transferred between trophic levels?
10%
200
What is a close relationship between 2 or more organisms called?
Symbiosis
300
What is the rhino's energy role? (Herbivore, Carnivore, or omnivore)
herbivore
300
How would the mouse population be affected if the owl was removed from the ecosystem? Why?
The mouse population will increase because they have no predators.
300
What level/order consumer is the fox?
secondary consumer
300
Name one secondary consumer heterotroph.
bird, frog, opossum
300
What is an apex predator? What type of consumer are they?
an animal at the top of the food chain that has no predators. Tertiary consumer
400
Name 3 types of consumers and explain the difference between each. (Herbivore, Carnivore, omnivore)
herbivore: eat only plants
carnivore: eat only meat
omnivore: eat plants and meat
400
Which population's extinction would have the greatest catastrophic effect on this food chain? Explain.
The grass. Producers are the foundation of all energy that flows through an ecosystem.
400
Name one food chain with at least 4 organisms from this food web.
example: phytoplankton > micronekton > predatory fish > shark
400
How many kcals of energy is available in the tertiary consumer level if the producer level has 10,000 kcals of energy?
10 kcals
400
Give an example of organisms competing for (1) an abiotic resource, and (2) a biotic resource
EXAMPLE: Abiotic: 2 Foxes competing for shelter// Biotic: Gorillas competing for a mating partner
500
What is a decomposer? Provide 2 examples.
Decomposers break down decaying biotic matter. Eg: Bacteria/fungus/worms
500
Which direction does the arrow point in a food chain? Why?
The arrow points from the organism getting eaten to the organism doing the eating. It shows the flow of energy through the ecosystem.
500
Explain why a food web is better for the ecosystem than a food chain. Provide an example.
The biodiversity of food webs allow for a more sustainable ecosystem in comparison to a food chain. Eg: food webs allow for organisms to feed off of multiple food sources if ever one goes extinct.
500
DOUBLE JEOPARDY: Define each of the following: Commensalism, Mutualism, Parasitism, Predation, & Competition
Commensalism: +/0, Mutualism: +/+, Parasitism: +/-, Predation: predator eating prey, Competition: 2 or more organisms competing for the same limited resource
500
What would happen if the rabbits were removed from this ecosystem? Explain how all other organisms are affected.
The plant population will increase because the rabbits are no longer eating them. With more plants, the inchworms have more food so they increase. Robins and merlins also increase due to having more prey. Wolves will decrease because they have no more food.
