All living organisms that inhabit an environment are called a community. A community includes multiple populations of organisms.

These populations rely on each other for survival. An example of a community is a coral reef. This includes many different species of fish living within a single ecosystem.

A biosphere is a form of classification called an organization level. This is primarily used by ecologists. Understanding these organizational levels lets ecologists look at groups of organisms and environments as a whole.

You can think of each organizational level as an organism itself.

These organizational levels in ecology are individual species, population, community, ecosystem, biome, and finally the all-encompassing biosphere.

Collection of several interacting populations that inhabit a common environment

A collection of several interacting populations that inhabit a common environment is a community. A community comprises interdependent populations of organisms that interact with one another.

A community can also be described as all of the organisms in a given location or area.

Communities are what make up a majority of the living components of an ecosystem.

A collection of ecosystems in a particular geographic location is called a habitat. All living organisms in a habitat share evolutionary similarities. This is due to the process known as environmental evolution.

All the organisms plus the nonliving components of a defined area

All the organisms plus the nonliving components of a defined area are an ecosystem.

Ecosystems are basically immovable bubbles of life, consisting of all the plants, animals, other organisms, land, and all additional components that affect life.

Ecosystem components are divided into biotic components and abiotic components.

Biotic components in an ecosystem:

·         Animals

·         Plants

·         Bacteria

·         Fungi

·         Virus’

·         Organic matter (E.g., dead plant matter)

Abiotic components in an ecosystem which are not part of an organism’s environment:

·         Water

·         Wind

·         Chemicals & Minerals (including nutrients)

·         Temperature

·         Light

·         Atmosphere

·         Radiation

·         pH

All of the living organisms in a forest plus their environment is an example of an ecosystem. An ecosystem is in a defined geographical area and includes all living things (biotic) and their non-living environment (abiotic).

The location and type of ecosystem affect which types of organisms live there. Organisms have to adapt to their environment to survive.

This means organisms that may thrive in a forest environment would not be able to survive in a desert environment. 

An example of a forest ecosystem is the redwood forest in Northern California. This forest environment is home to many birds, squirrels, chipmunks, and frogs. 

Which of the following terms describes all organisms on earth plus their environments

The term that describes all organisms on earth plus their environments is called the biosphere. The biosphere consists of all environments on earth that support life

This includes every ecosystem and biome. The biosphere extends from deep ocean volcanoes to the darkest caves.

The sum of a species’ use of the biotic and abiotic resources in its environment is called

The sum of a species’ use of the biotic and abiotic resources in its environment is called its ecological niche. An ecological niche can be seen as a species’ specific living conditions within an ecosystem.

Sum of a species use of the biotic and abiotic resources

The ecological niche defines where an organism fits into its ecosystem. This niche or spot in the ecosystem can only be occupied by one species at a time.

Which set of three parameters has the most effect on biome distributions?

The set of three parameters that have the most effect on biome distributions are location, precipitation, and temperature.

Location affects biome distributions because areas closer to the equator will be warmer and therefore can hold more moisture.

Set of three parameters that have the most effect on biome distributions

Higher latitude biomes are colder and drier because they are further away from the equator. 

Precipitation will affect the type of plants present in a specific biome. Biomes that receive higher levels of precipitation will contain a higher density of plant life.

Temperature affects biome distribution because animals require specific temperature levels to survive.
