The number of species living within an ecosystem is a measure of its ______________________.
A somewhat regular progression of species replacement is called ______________________.
A(n) ______________________ consists of a community
and all the physical aspects of its habitat, such as the soil, water, and weather.
Animals, plants, and other photosynthesizing organisms play important roles in the ______________________ ______________________.
Ammonification is the first stage in the ______________________ ______________________.
A large region that is characterized by a specific kind of climate is called a ______________________.
The many different species that live together in a habitat are called a(n) ______________________.
The average weather conditions in an area over a long period of time is the area's ______________________.
Calcium phosphate stored in soil and rock dissolves in water as part of the ______________________ ______________________.
The exchange of oxygen and carbon dioxide between living cells and their environment is called ______________________.
The place where a particular population of a species lives is called its ______________________.
Where an organism lives
A triangular diagram that shows an ecosystem's loss of energy as energy passes through a food chain
Fixes nitrogen for use by living things
An organism in an ecosystem that first captures energy
Consistent weather patterns in an area over time
A measure based on the variety of species in an area
Photosynthesis and respiration are two important components
Organism that obtains energy by consuming plants or other organisms
Root uptake and consumers eating plants are important parts of this process
A step in the transfer of energy through an ecosystem
An organism that obtains energy from organic wastes and dead bodies
Carbon dioxide is returned to the atmosphere in this process
Various interacting species and their physical environment
Characterized by its climate and kinds of species
Begins with pioneer species
A group of species that live in the same place and interact with one another.
