Answer 2

An ecosystem changes over time due to several factors and occurrences

these occurrences are the breaking up of Gondawonda about 600 million years ago to give us something that we see today being continents and poles it just used to be Antarctica and everything drifted off that, then we have precession the fact that the stars drop by 1 degree every year proving we are wobbling on our poles by 26 degrees over a cycle of 26000 years, this effects the seasons and they will go to every extreme over that 26000 year cycle from hot summer to sub zero temperatures the seasons would completely reverse over a 13000 year period on a given day of the year, from this we have formed ecosystems we see today of rainforest's to desert and frozen areas on earth, with different sorts of life carrying out various needs in the maintenance of nature in that phase of the 26000 year cycle, the lifeforms will have to contend with weather changes that effect the ecosystem, the ecosystem may also be attacked at times by fire and flood causing minor earth changes.
