- Hey everyone!
- YAYYY
- INTERESTING🤔
- Today we will talk about Primary and Secondary succession
- Welcome to todays Books+Cookies
- WHAT!
- Did you know that in summer of 1988 Yellow Stone National Park had fires raging?
- THERE IS NO WAY
- Yeah! Large areas were burnt to the ground and once all the fires were out grey ash blanketed the ground.
- Many dead trees fell over. Green plants were growing very quick in large amounts.
- woah
- In 1988 scientists reported that the forest was growing back
- The regrowth of a burnt area is called succesion
- Communitys can grow in places that no other organism has lived before there is no soil in these areas and is usually just bare rock
- SO INTERSTING!!
- over time species will live and die on a rock the rock is then slowly turned into soil. This is called primrary succesion!
- Jill we should go explore primary succesion after this
- the first species to live in these place are called pioneer species- a pioneer species is a species that colonises an uninhabitated are and starts succesion
- Sometimes a community is destroyed by a natural disaster. Other times it could be something else
- Huh! Not to bad
- if soil is left intact the original community could regrow through a series of stages called secondary succesion
- THANKYOU EVERYONE
- WOW!!! That was really interesting
