What is the role of fire in ecology?
What is the role of fire in ecology?
- Create barren and lifeless areas
- Increase populations and stabilize communities
- Disturb populations and move communities (correct)
- Prevent colonization in habitats
When considering ecological succession, what is the difference between primary and secondary succession?
When considering ecological succession, what is the difference between primary and secondary succession?
- Primary is faster than secondary
- Primary occurs after a forest fire, secondary occurs after a flood
- Primary leads to barren lands while secondary leads to lush forests
- Primary involves the first colonization of a barren area, secondary recognizes a habitat after a disturbance (correct)
