UNIT 4 Revisit - Cycles, Succession, Macromolecules

Front

What type of succession occurs after a disturbance that does not destroy the soil?

Back

Secondary succession occurs after a disturbance that does not destroy the soil, allowing for the recovery of the ecosystem.

Front

What is a Climax Community?

Back

A Climax Community is a stable, final stage of ecological succession, where the ecosystem reaches a state of balance.

Front

What are Pioneer Species?

Back

Pioneer Species are the first organisms to colonize previously disrupted or damaged ecosystems, such as lichen or algae after primary succession.

Front

What is the process of Nitrogen-Fixation?

Back

Nitrogen-Fixation is the process where free nitrogen in the atmosphere is converted into nitrogen compounds by certain bacteria.

Front

Define 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.

Front

What is Ecological Succession?

Back

Ecological Succession is the gradual process of change and replacement in the species composition of a given area.

Front

What role do Decomposers play in an ecosystem?

Back

Decomposers break down dead organic material, returning nutrients to the soil and supporting new plant growth.

Front

What is an example of a Climax Community?

Back

A redwood forest is an example of a Climax Community, characterized by a stable and diverse ecosystem.

Front

What is the difference between Primary and Secondary Succession?

Back

Primary Succession occurs in lifeless areas without soil, while Secondary Succession occurs in areas where soil is present after a disturbance.

Front

What is a Niche in an ecosystem?

Back

A Niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions.
