primary production, respiration, energy, carbon and nutrient flow through food webs, reproduction, and decomposition
are represented as rates of change, which requires repeated measurement over time.

Soil formation. ...
-
Nutrient cycling. ...
-
Biomass production. ...

Levels of organization in ecology include the population, community, ecosystem, and biosphere.
-
An ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.
What are the main parts of an ecosystem?
An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its
biotic constituents
, consisting of all its living members.
What are the 3 main nutrient cycles in an ecosystem?
The three main cycles of an ecosystem are
the water cycle, the carbon cycle and the nitrogen cycle
. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.
