Matter and Energy
How matter moves within an ecosystem.
What is a cycle? (or cyclical)
Definition of niche.
What is the the role/job something holds in an ecosystem?
This is the original source of all energy.
What is the sun?
What is a symbiotic relationship?
The effect of deforestation on the environment.
What is an increase in CO2 levels and/or habitat loss?
How energy moves in an ecosystem.
What is flow?
This is what something that makes its own food is called.
What is a producer/autotroph?
The thing that arrows in a food web show the direction of.
These are the three types of symbiotic relationships.
What are mutualism, commensalism, and parasitism?
Non-native species (often brought by humans) that can harm an ecosystem.
What is an invasive species?
These are the biology terms for living and non-living.
What are biotic and abiotic?
This is what something that must get its energy from other organisms is called.
What is a consumer?
This much energy is LOST between each level of a food pyramid.
What is 10%?
The description of what would happen to the snake population in the following food chain if the hawk were removed.
grass -> grasshopper -> bird -> snake -> hawk
What is the snake population would increase until they overeat the birds and run out of food?
This is why invasive species are so harmful.
What is they have no natural predators, so their numbers grow unchecked outcompeting native species for resources?
This type of organism in an ecosystem most directly requires CO2.
These are the three consumer diets and what they eat.
What are herbivore (plants), omnivore (both), and carnivore (animals)?
Organisms at the top of a food chain can be dangerous to eat for vulnerable populations (like pregnant women) for this reason.
What is biomagnification?
The description of what would happen to the bird population in the following food chain if the hawk were removed.
grass -> grasshopper -> bird -> snake -> hawk
What is the bird population would decrease because there would be more snakes eating them?
This is the main way humans have disrupted the carbon cycle.
What is burning fossil fuels?
These are the organisms most directly responsible for recycling matter in an ecosystem (by releasing that matter from dead organisms).
What are decomposers?
This is what we call an organism that is not fed on by any other organisms.
What is an apex/top predator?
This is the level of a food chain/pyramid that will have the greatest number of individuals and why.
What are the producers because much energy is lost at each trophic level, so consumers must eat many producers to gain adequate energy?
What is commensalism?
This is the explanation for how climate change can be traced back to humans.
What is humans release many greenhouse gasses through industry, travel, and mass agriculture, which trap heat in our atmosphere, raising the temperature?
