EROSION

The number of species living within an ecosystem is a measure of its ______________________.

BIODIVERSITY

A somewhat regular progression of species replacement is called ______________________.

SUCCESSION

A(n) ______________________ consists of a community
and all the physical aspects of its habitat, such as the soil, water, and weather.

ECOSYSTEM

Animals, plants, and other photosynthesizing organisms play important roles in the ______________________ ______________________.

CARBON CYCLE

Ammonification is the first stage in the ______________________ ______________________.

NITROGEN CYCLE

A large region that is characterized by a specific kind of climate is called a ______________________.

BIOME

The many different species that live together in a habitat are called a(n) ______________________.

COMMUNITY

The average weather conditions in an area over a long period of time is the area's ______________________.

CLIMATE

Calcium phosphate stored in soil and rock dissolves in water as part of the ______________________ ______________________.

PHOSPHOROUS CYCLE

The exchange of oxygen and carbon dioxide between living cells and their environment is called ______________________.

RESPIRATION

The place where a particular population of a species lives is called its ______________________.

HABITAT

Where an organism lives

HABITAT

A triangular diagram that shows an ecosystem's loss of energy as energy passes through a food chain

ENERGY PYRAMID

Fixes nitrogen for use by living things

NITROGEN CYCLE

An organism in an ecosystem that first captures energy

PRODUCER

Consistent weather patterns in an area over time

CLIMATE

A measure based on the variety of species in an area

BIODIVERSITY

Photosynthesis and respiration are two important components

CARBON CYCLE

Organism that obtains energy by consuming plants or other organisms

CONSUMER

Root uptake and consumers eating plants are important parts of this process

PHOSPHOROUS CYCLE

A step in the transfer of energy through an ecosystem

TROPHIC LEVEL

An organism that obtains energy from organic wastes and dead bodies

DECOMPOSER

Carbon dioxide is returned to the atmosphere in this process

RESPIRATION

Various interacting species and their physical environment

ECOSYSTEM

Characterized by its climate and kinds of species

BIOME

Begins with pioneer species

SUCCESSION

A group of species that live in the same place and interact with one another.

COMMUNITY
