Ecological Succession

Ecological Succession can best be described as...​ ​ (a)  

• Series of changes in a community over time
• A gradual change in the weather.
• The dominant species in one particular area.
• Species that survive best with no competition
• Plants growth response to a stimulus

A forest full of MATURE PINE TREES that is fully recovered from a disturbance is an example of...​ (a)  

• Climax community
• Pioneer Species
• Intermediate species

When a farm or garden is left unplanted, SECONDARY SUCCESSION occurs, returning the land to a mature, climax community. What is the order that reflects how plants will emerge in the new community: ​ (a)   ​ ​ (b)   ​ (c)   ​ (d)  

• 1st step

• Wildflowers/Perennials

• 3rd step

• Grasses and weeds

• 2nd step
