Nonliving components of an ecosystem

an organism that can produce its own food

all interacting populations of different species that live in the same geographic location at the same time

total mass of living matter at each trophic level

large group of ecosystems that share the same climate and have similar types of communities

relatively thin layer of Earth and its atmosphere that supports life

any living factor in an organism's environment

heterotroph that prays on other heterotroph

largest number of individuals in a species that an environment can support long term

heterotroph that decomposes organic material and returns the nutrients to soil, air and water making the nutrients available to other organisms

scientific study of all the interrelationships between organisms and their environment

biological community and all the nonliving factors that affect it

simplified model that shows a single path for energy flow through an ecosystem

model that shows many interconnected food chains and pathways in which energy and matter flow through an ecosystem

physical area in which an organism lives

heterotroph that eats only plants

organism that can't make its own food and gets its nutrients and energy requirements by feeding on other organisms

seasonal movement of a group of animals

symbiotic relationship in which both organisms benefit

role, or position, of an organism in its enivonment

heterotroph that consumes both plants and animals

group of organisms of the same species that occupy the same geographic place at the same time

increase in the number of organisms who inhabit the area

relationship between animals in which one organism captures and feeds on others

any class of organisms that occupy the same position in a food chain, as primary consumers, secondary consumers, and tertiary consumers
