Question | Answer |
The living components of the world: in ecosystems these include all living things | Biotic |
The non-living components of the world: these include sunlight, wind, nutrients, and minerals | abiotic |
an organism that lives on decaying organic material, from which it obtains energy and its own raw materials | Decomposer |
the process of putting together or building up the large molecules characteristic of a particular type of cell tissue, in other words, reactions that put create the macromolecules needed for life. | Biosynthesis |
What does bio mean? | Life |
The study of living and nonliving components of the environment and of the interactions that affect biological species | Ecology |
In what ways might elements in the waste matter of one organism be useful to another? | These can be useful nutrients when they are decomposed that other organisms need |
A biological community in its abiotic environment | Ecosystem |
when the types and amounts of matter in an ecosystem remain the same across time the ecosystem remains in _____ | Balance |
When the types of matter in a ecosystem change, the ecosystem is forced to ________ | Change |
not only does matter move through an ecosystem but some of it makes a complete ____ within it | Cycle |
This cycle collects and redistributes the earths water supply | Water cycle |
in a stable ecosystem the total number of carbon atoms will remain approximately the same. this is in what cycle? | Carbon cycle |
Four main processes that move carbon? | Biological process, burial and decomposition process, geochemical process, and human process |
The atmosphere is the main reservoir of nitrogen: it also cycles through the soil and tissues of living organisms. this is what cycle | Nitrogen cycle |
Levels of organization in ecology | Organism, population, community, ecosystem, biosphere |
all the organisms that inhabit a particular area and interact with one another | Community |
the outer portion of the earth where life is found | Biosphere |
What is the smallest level of ecology organization? | Organism |
What is the largest level of ecology organization? | Biosphere |
the dry weight of organic matter that makes up a group of organisms in a particular habit. | Biomass |
The portion of biological matter at a trophic level that is available for consumption by organisms at higher trophic levels | Consumable biomass |
A group of organisms in a community that occupies the same position in the food web, such as producers or primary consumers | Trophic level |
What does troph mean? | food |
An organism that is able to make and store food, using sunlight or another non living energy source | Autotroph, producer |
An organism that obtains carbon and all metabolic energy from organic molecules previously assembled by autotrophs | heterotroph, consumer |
an organism that lives on decaying organic material, form which it obtains energy and its own raw materials for life | Decomposer |
An animal that eats only animal matter | Carnivore |
An animal that eats only plant matter | Herbivore |
An animal that eats both animal and plant matter | Omnivore |
a simple model that shows how matter and energy move through an ecosystem consisting of three to five steps | Food chain |
What represents the direction of energy flow | Arrows |
A model that expresses all the possible feeding relationships at each trophic level in a community or ecosystem | Food web |
A model that shows the amount of energy in each trophic level of a community or ecosystem | Energy (Food) pyramid |
States that only about 10% of the original energy is left to feed the next trophic level - the other 90% of available energy is used for life processes and transformed to heat energy before an organism is consumed | 10% rule |
Levels of Consumers from the lowest to the highest | Primary consumers, secondary consumers, tertiary consumer, quaternary consumers |
Organism that eats the producer | Primary consumer |
Organism that eats the primary consumer | Secondary consumer |
Organism that eats the secondary consumer | Tertiary consumer |
Organism that eats the tertiary consumer | Quaternary consumer |
