Question

select the statement(s) that accurately describe the stages of succession. stage iv through stage vi would involve bare rock with lichens and moss. some living organisms found in stages v and vi may also occur in stage vii. stage ii would involve bare rock with lichens and moss. stage vii represents the mature, climax community. stage iii occurs after soil formation from stage ii.

Explanation:

• In ecological succession, the pioneer stage (usually early - not stage IV - VI) involves bare rock with lichens and moss, so the first statement is incorrect.
• As succession progresses, some organisms can persist across adjacent stages, so it's possible for organisms in stages V and VI to also be in stage VII.
• The pioneer stage with bare rock, lichens and moss is typically stage I or early succession, not stage II.
• Stage VII often represents the climax community which is a stable, mature community.
• After the pioneer stage (stage II might be part of pioneer or early succession), soil formation occurs and then stage III with more complex plant life can follow.

Answer:

B. Some living organisms found in stages V and VI may also occur in stage VII.
D. Stage VII represents the mature, climax community.
E. Stage III occurs after soil formation from stage II.
