What is the primary difference between primary succession and secondary succession?
What is the primary difference between primary succession and secondary succession?
- Primary succession begins on bare rock, whereas secondary succession occurs in areas where soil is already present. (correct)
- Primary succession is faster than secondary succession in terms of species colonization.
- Primary succession occurs in previously inhabited areas while secondary succession does not.
- Secondary succession leads to the creation of aquatic ecosystems, while primary succession does not.

Study Notes
Interactions and Ecosystems
- Predator-prey relationships can be graphed
- Food webs show energy flow
- Energy flows through ecological pyramids
- Primary succession differs from secondary succession
- Ecosystems have abiotic (non-living) and biotic (living) components
- Symbiosis includes commensalism, mutualism, and parasitism examples
- Ecological footprint measures environmental impact; activities affect it
- Key terms related to endangered species, migration, extinction, behavioral/structural adaptations.
- Concepts of deforestation and its consequences
- Types of consumers: carnivores, herbivores, omnivores
- Predator-prey relationships exist in ecosystems
- Producers (plants) and their role in ecosystems
- Biodiversity is essential in terms of ecosystem health
Heat and Temperature
