Question

complete the venn diagram using the bulleted phrases below. - no previously existing life - plants and animals adapt - comes after a natural disaster - climax community - starts as a result of a forest fire or flood - happens relatively slow - happens relatively fast - previously existing life - pioneer species - starts with previously existing soil - starts on bare rock - lichens break down rock - gradual growth - starts as the result of a volcano or receding glacier primary succession both secondary succession

Explanation:

To solve this Venn diagram for primary and secondary succession, we analyze each phrase:

Primary Succession (Left Circle):

• No previously existing life (starts from scratch, e.g., after a volcano or glacier recedes).
• Starts on bare rock (no soil initially).
• Lichens break down rock (pioneer species that create soil).
• Starts as the result of a volcano or receding glacier (disturbances that leave no life/soil).
• Gradual growth (slow, as it builds from bare rock).

Secondary Succession (Right Circle):

• Previously existing life (starts after a disturbance like fire/flood that leaves soil/life).
• Starts as a result of a forest fire or flood (disturbances that leave soil and some life).
• Happens relatively fast (soil and life remnants speed up recovery).
• Comes after a natural disaster (fire, flood, etc.).
• Starts with previously existing soil (soil is already present).

Both (Overlap):

• Pioneer species (both have species that initiate succession).
• Happens relatively slow (primary is slow, secondary is faster but still gradual? Wait, correction: Primary is very slow, secondary is faster. Wait, the phrase “happens relatively slow” may belong to primary, but “happens relatively fast” to secondary. Wait, re-express:
• Both: Gradual process (succession is always gradual), pioneer species (both have species that start the process), plants and animals adapt (both involve ecological adaptation), climax community (both aim for a stable climax community).

Final Categorization:

Primary Succession	Both	Secondary Succession
Starts on bare rock	Gradual growth	Starts with previously existing soil
Lichens break down rock	Plants and animals adapt	Starts as a result of a forest fire or flood
Starts as the result of a volcano or receding glacier	Climax Community	Happens relatively fast
Happens relatively slow		Comes after a natural disaster

(Note: Adjust based on precise definitions: Primary = starts on sterile substrate (no life/soil); Secondary = starts on disturbed substrate (soil/life remains). So “happens relatively slow” is primary, “fast” is secondary. “Gradual growth” is both, as succession is gradual. “Pioneer species” is primary (lichens/mosses) and secondary (grasses/weeds), so both. “Climax community” is the end goal of both. “Plants and animals adapt” is both, as adaptation occurs in all succession.)

Filling the Diagram:

• Primary: No previously existing life, Starts on bare rock, Lichens break down rock, Starts as the result of a volcano or receding glacier, Happens relatively slow.
• Both: Pioneer Species, Gradual growth, Plants and animals adapt, Climax Community.
• Secondary: Previously existing life, Starts as a result of a forest fire or flood, Happens relatively fast, Comes after a natural disaster, Starts with previously existing soil.

This organizes the phrases into the Venn diagram based on ecological succession definitions.
