What are some similarities between salt marshes and mudflats? I need help please!

Mudflats and saltmarshes arise where high tides occur in areas of extremely low wave energy, such as behind spits, in bays or at the top of long, flat beaches. Both mudflats and saltmarshes are very productive habitats in terms of animal life and are rich in mud-dwelling invertebrates. These in turn are the food of huge numbers of migrant wading birds. Hope this helps a little.

Explanation:

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
