What is succession?

• The first species to populate an area.

• Is the same of intereaction

• Is Disruption to the physical or biological components.

• The series of predictable changes that occur in a community over time.

What is colonize?

• When an ecosystem is harm in any way.

• to establish a colony in or of

• Yes it can

• No it cant

the first organisms that appear in an ecological community

• ecological succession

• primary succession

• secondary succession

• pioneer species

Primary Succession is...

• The first species to populate and area

• The series of changes that occur in an area where no soil or organisms exist

• Ecosystems that are dynamic

When longleaf pine trees are said to "dominate" an ecosystem, what does that mean?

• The longleaf pine trees are in competition with the shortleaf pine trees

• The longleaf pine trees dominate that ecosystem

• The longleaf pine trees are almost extinct in that ecosystem

After a volcanic eruption, lava covers the land. What is the order that plants grow to repopulate the area?

• Lichens → Shrubs → Grasses → Trees
• Lichens → tree → shrubs→Grasses
• Grasses → Lichens → Shrubs → Trees
• Lichens → Grasses → Shrubs → Trees

What are examples of pioneer species in a primary succession?

• Bushes and Shrubs
• Oak trees
• Mossess and Lichens 
• A rose Bush

the process by which a new community forms where no community lived before 

• resource
• invasive (non- native) species
• primary succession
• competition

What is the first species you will see after a primary succession? (in picture)

• lichens
• grasses
• small plants
