Biomes, Succession & Biodiversity

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What does low biodiversity indicate about an ecosystem?

Back

Low biodiversity can indicate an ecosystem that is less resilient to changes and disturbances, and it may be more vulnerable to extinction of species.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, illustrating how energy and nutrients flow through the system.

Front

What do the arrows in a food web represent?

Back

The arrows in a food web represent the flow of energy from one organism to another.

Front

What is an indicator species?

Back

An indicator species is a species whose presence, absence, or abundance reflects a specific environmental condition, often used to assess the health of an ecosystem.

Front

Why are frogs considered indicator species?

Back

Frogs are considered indicator species because they are sensitive to changes in air and water quality due to their permeable skin, which absorbs both oxygen and toxins.

Front

What two measurements are typically found on a climatogram?

Back

A climatogram typically displays rainfall and temperature data for a specific location over a period of time.

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil and some organisms still exist, such as after a forest fire or flood.

Front

What role does climate play in determining biomes?

Back

Climate, including temperature and precipitation patterns, plays a crucial role in determining the types of biomes that can exist in a particular region.
