Explain one reason why it is hard
for animals to survive in the tundra.

Biodiversity, the amount and variety of life in this tundra environment, is low because; The temperatures and precipitation in these tundra areas are both LOW, and these abiotic factors mean that this is a very difficult environment for life to survive, as there is minimal water and sunlight available for survival.

Explanation:

I hope that this helped you ;)

Tundras are very big deserts. But it's cold, right? The thing that defines a desert is its low level of percipitation, not its temperature. Anyway, it is hard because for one the tempreatures are super low and cold, and two, it's a desert, and it has very little rainfall.

Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D

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.

what events in mexico's history might explain why the country continues to have difficulty improving social justice and economic opportunities for all people?
