Question

directions: draw a line matching each item from column a to column b.
column a
takes place after an existing community is destroyed
the ability of living things to survive the changes in their environment
takes place on land where there are no living organisms
anything that limits an organisms ability to live in an environment
a stable community with little or no change
column b
primary succession
secondary succession
climax community
tolerance
limiting factor
directions: compare and contrast primary and secondary succession.

Explanation:

1. Takes place after an existing community is destroyed: This is secondary succession as it occurs when a pre - existing community is disrupted.
2. The ability of living things to survive the changes in their environment: This is tolerance. Organisms with higher tolerance can better adapt to environmental changes.
3. Takes place on land where there are no living organisms: This is primary succession which starts in areas with no pre - existing life.
4. Anything that limits an organism's ability to live in an environment: This is a limiting factor which restricts the growth, distribution, or abundance of an organism.
5. A stable community with little or no change: This is a climax community which is the final stage of ecological succession.

For the Venn - diagram comparison of primary and secondary succession:

• Differences:
• Primary succession occurs in areas with no pre - existing soil or life (e.g., on newly formed volcanic islands). Secondary succession occurs in areas where a community has been disturbed but soil and some life forms remain (e.g., after a forest fire).
• Primary succession takes a much longer time to reach a climax community compared to secondary succession.
• Similarities:
• Both are processes of ecological succession where the community changes over time.
• Both lead to the development of a more complex and stable community over time.

Answer:

• Takes place after an existing community is destroyed: secondary succession
• The ability of living things to survive the changes in their environment: tolerance
• Takes place on land where there are no living organisms: primary succession
• Anything that limits an organism's ability to live in an environment: limiting factor
• A stable community with little or no change: climax community
• For the Venn - diagram: Differences and similarities as explained above should be filled in the appropriate sections of the circles representing primary and secondary succession.
