Question

Which statement best describes ecological succession?
It is always caused by human intervention.
It sometimes occurs after a disturbance.
It always occurs in a predictable pattern.
It is a series of rapid changes in an ecosystem.

Answer 1

Hmm well its defiantly not D because it happens over a extended period of time

Answer 2

I would say B

Answer 3

says B is wrong.

Answer 4

Hmm okay well what do you think?

Answer 5

B is the more appropriate among the given options

Answer 6

A is wrong because forest fires can happen without human intervention and succession often follows after a forest fire.
B is wrong because it always happens after a disturbance.
D is wrong because it isn't rapid at all: it takes loads of time.

therefore, by process of elimination, C is right.

Answer 7

YOU CANNOT MAKE AN ACCURATE PREDICTION OF ECOLOGICAL SUCCESSION DUE TO COMPLEXITY OR COMPLEX INTERACTION OF COMPLEX SYSTEMS - GEOLOGY, HISTORY, CLIMATE, MICROCLIMATE, SOIL AND OTHER ENVIRONMENTAL FACTORS LIKE SPECIES' ABILITY TO ADAPT OR THRIVE IN A GIVEN AREA. NEVERTHELESS, WE CAN MAKE SOME PREDICTION THAT IS ORDERLY (PATTERN) OR IN WHICH HOW THE SUCCESSES OCCUR OR MAY OCCUR.

REALISTICALLY, THE RAPID CHANGES OCCUR IN THE SMALLEST SCALE AND ARE NOT READILY OBSERVABLE BUT OVER A LONG PERIOD OF TIME - THE TRUE DEFINITION OF ECOLOGICAL SUCCESSION IS THAT IT OCCURS IN DIFFERENT TIME SCALES.

I GUESS THE MORE YOU LEARN ABOUT BIOLOGY AND ECOLOGY THE MORE THESE SIMPLE DEFINITIONS START TO BLUR. IT IS JUST LIKE USING A MICROSCOPE, WE STUDY THESE THINGS BY CONTINUALLY ZOOMING IN AND OUT - ZOOM IN TO OBSERVE THE MOST INTRICATE AND DETAILED INFORMATION AND ZOOM OUT TO MAKE A GENERAL OBSERVATION.
