Ecology

shows the distribution of energy among trophic levels

movement of a particular chemical through the biological and geological parts of ecosytem

producers provide energy for other organisms in an ecosystem

Biome

cycling indirectly through an ecosystem by the cycling of other nutrients

is a model that shows a sequence of feeding relationships

every food chain starts with

logistics growth

levels in a food chain or pyramid 

Movement of organisms into a population

commensalism

shows a complex network of feeding relationships

movement of organism out of a population

study of the relationship among organisms and their environment

exponential growth

parasitism

Carbon Cycle Moves carbon from the_______________through ___________and returns to_____________

hydrologic cycle 

things that can cause biodiversity loss

takes place underground, converts gas into ammonia

Mutualism

what models the flow of energy in an ecosystem 

Factors that are living things 

Could an invasive species affect an entire ecosystem

What cycles in and out of a ecosystem
