Lesson 3.01
Succession
● Explain in your own words what primary succession is (See page 1 from lesson 03.01)
○ Where (under what conditions) would primary succession tend to occur? Be very
specific
○ What would be evidence of primary succession? List all characteristics in detail
Occurs when a new ecosystem is built from scratch. It is the evolution of a biological
community’s ecological structure which plants and animals first colonize a lifeless
habitat. Through their interactions they build simple biological community. Primary
succession begins in barren areas like rock formations such as volcanoes or
mountains or in a place with no organisms or soil.
After a volcanic eruption, lava flows over an area and cools to form new rock. 1,000
years later a forest with different organisms and flowers are found in that area.
○ Define and give examples of a pioneer species - especially for a primary succession
area
Examples of Pioneer species: Species that arrive first in the newly created
environment are called pioneer species. Algae, fungi, bacteria, lichens colonize on
the bare rocks and provide organic materials for a higher level of colonization, while
the planktons, phytoplankton’s and zooplanktons provide base at the shallow water
for a higher level of succession.
● Explain in your own words what secondary succession is (See page 1 from lesson 03.01)
Occurs when an ecosystem is rebuilt after a major disaster. Seasonal and climate changes
also impact ecosystems and their inhabitants.
● Would primary or secondary succession have higher biodiversity faster and why?
Secondary succession would have a wider biodiversity faster as there is already a basis for
which lifecan exist, and it is first come first serve to many organisms
● Be able to interpret a migration map
● What are reasons for seasonal migrations?
As warmer water temperatures shift, so do warm and cold loving marine species. Warmer
water temperatures also deplete vital nutrients, which can cause species to migrate
elsewhere to feed. Once those species shift, so must the predators that rely on them for
