Which of the following is the most likely cause for succesion in ecosystems? a. arrival of new speciesb. rainc. loss of an animal speciesd. wildfires

Hello.

The D. wildfires

For  succesion in ecosystems nothing remains the same or constaly changing. New specis, Rain and loss of animals can change an everment but only a Wildfire can change a ecosystem where nothing is left the same. So therefore the answer is Wildfires.

Have a nice day.

not too sure but maybe in the hot springs.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
