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
