Energy VS Matter
Has mass and takes up space and is recycled through air, soil, and organisms. Energy or Matter?
Matter
What does biotic mean?
Living Things
What will happen to an ecosystem if there is an increase in predators?
Primary consumers will decrease
Producers will increase
How much energy do PRODUCERS (plants) take in from the sun?
100%
What is an producer?
Makes its own food
Enters as sunlight, transfers through food chains, and exits as heat. Energy or Matter?
Energy
What does abiotic mean?
Nonliving Things
What will happen in an ecosystem if primary consumers decrease?
Predators will decrease
Producers will increase
How much energy goes to a primary consumer from a prodcuer?
10%
What is a consumer?
Needs to eat to gain energy
What is being transferred? A sea otter uses ATP to swim away from an orca (killer whale)
Energy in the form of ATP
Is the following biotic or abitioic?
Water
Abiotic
NO!
There will be more than enough food for the levels above if we have "too many" producers
How much energy is "lost" in an energy pyramid from producer to primary consumer?
100-10= 90%
What is a decomposer?
Breaks down, eats, or filters dead organisms and detritus from an ecosystem
What is being transferred? A mollusk filters out waste and detritus out of the water and recycles the clean water back into the ecosystem.
Matter in the form of detritus, waste, and water
Is the following biotic or abitioic?
Sunlight
What could happen to a kelp forest if otters leave the ecosystem?
Sea urchins would increase in population and overeat the kelp, causing a collapse of the ecosystem
What percentage of energy does a Secondary Consumer get in an energy pyramid?
Producer=100%
Primary consumer= 100/10= 10%
Secondary consumer= 10/10= 1%
What is the difference between herbivore, omnivore, and carnivore?
Herbivore= plant eater
Omnivore= eats plants and animals
Carnivore= eats only animals
What is being transferred? A sea star eats the remains of a fish from the sea floor, digests the meat, and uses cellular respiration to make ATP to regrow a missing limb.
BOTH!
Matter in the form of the fish remains
Energy in the form of ATP for limb regrowth
Is the following biotic or abitioic?
Waste
Biotic
In a healthy ecosystem, rank the following from highest wanted population to lowest:
Primary Consumer, Producer, Predator
Producer: Most
Primary consumer: Middle
Predator: Smallest
What percentage of energy would a quaternary consumer get in an energy pyramid?
Producer=100%
Primary consumer= 100/10= 10%
Secondary consumer= 10/10= 1%
Tertiary Consumer= 1/10= 0.1%
Quaternary consumer= 0.1/10= 0.01%
What are the other terms for consumer and producer
Consumer= heterotroph
Producer= Autotroph
