Term
Living parts of an ecosystem are called what?
Definition
biotic factors
Term
Non-living parts of an ecosystem are called what?
Definition
abiotic factors
Term
These get their energy by eating other organisms.
Definition
consumers
Term
What do we call the scientific study of how organisms interact with their environment and all the other organisms found there?
Definition
ecology
Term
What is a particular environment and all the living things that are supported by it?
Definition
ecosystem
Term
This element is the "backbone" for all living things. It is not a living organism without it.
Definition
carbon
Term
Almost 80% of the air that you breathe is made of what element?
Definition
nitrogen
Term
Most of the earth's carbon is located where?
Definition
the oceans
Term
Give me two examples of a fossil fuel.
Definition
Natural gas, oil, coal
Term
These are the "clean-up" crew of the ecosystem.
Definition
decomposers
Term
List two biotic factors in a desert.
Definition
cactus, rattlesnake, lizard, camel
Term
List two abiotic factors in the open ocean.
Definition
water, sunlight, sand, dirt, air, temperature, dead fish, etc.
Term
List three different ecosystems.
Definition
pond, river, mountain, jungle, prairie, desert, forest, etc.
Term
Name three objects that contain carbon.
Definition
pencil, diamond, coal, gas, sugar, all plants, all animals
Term

Tell me the order of a food chain using the following organisms:

 

locust, snake, leaf, frog

 

 

Definition

locust (primary) eats the leaf (producer)

 

frog (secondary) eats the locust (primary)

 

snake (tertiary) eats the frog (secondary)

 

Term
In the energy pyramid, where are most organisms found?
Definition
producers (at the bottom of the energy pyramid)
Term
What organisms are producers?
Definition
plants
Term
In the energy pyramid, where are the least amount of organisms found?
Definition
tertiary consumers
Term
Name two tertiary consumers.
Definition
humans, bears, lions, tigers, sharks
Term
Where would you place a cow in the energy pyramid?
Definition
primary consumer
Term
Where would you place a frog in the energy pyramid?
Definition
secondary consumer
Term
Is energy lost or gained as you go up the energy pyramid?
Definition
energy is lost
Term
A plant uses the sun's energy, water, and and carbon dioxide to produce what?
Definition

carbohydrates (sugars)

 

(plants release oxygen and water vapor)

Term
What do we call the process whereby the plants use the sun's energy to produce food?
Definition
photosynthesis
Term
What gas do humans breathe out (exhale) as waste other than water vapor?
Definition
carbon dioxide (CO2)
Term
The oil, gas, and coal we use today was created millions of years ago by what?
Definition
dead plant and animal matter deep in the ground
Term
Matter might change form but it never leaves the what?
Definition
ecosystem
Term
A food web is several overlapping what?
Definition
food chains
Term
A tomato and an apple are examples of what?
Definition
producers
Term
A rabbit and a deer are examples of what?
Definition
primary consumers
Term
Give three examples of decomposers.
Definition
bacteria, fungus (mushrooms), millipedes, centipedes, maggots, earthworms, termites, pill bugs, etc.
Term
These make energy available to all other living things.
Definition
producers (plants)
Term
List three things that decomposers might digest.
Definition
dead leaves, dead roots, dead branches, dead animals
Term
Water vapor that is cooled, sticks to a surface such as dust, gets close together, and often forms clouds is called what?
Definition
condensation
Term
What is respiration?
Definition
the release of water vapor into the air by animals
Term
What do we call the release of water vapor into the air by plants?
Definition
transpiration
Term
Water changing into water vapor because of increasing temperatures is called what?
Definition
evaporation
Term
When water vapor condenses and cools down enough, what part of the water cycle occurs next?
Definition
precipitation
Term
What is runoff?
Definition
water flowing down mountains, hills, or slopes in the form of rivers or streams
Term
Why do we get less energy from eating a rabbit after the rabbit has eaten carrots?
Definition
Because the rabbit has burned off some of the energy by running, moving about, giving off body heat, etc., etc.
Term
When precipitation occurs you normally have runoff and what other part of the water cycle should occur?
Definition
water will seep into the earth (groundwater)
