Biology chapter 9 review

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
