Why should organisms that produce more offspring have a more likely chance of survival?

Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.

Explanation:

I will try to put this in the simplest terms I can:

If you think about it, organisms actually do not live that long. There are multiple cause and effect reasons, such as low resources, no food, extinction, and so on. Thus, organisms must produce offspring to keep their "family line" consistent.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
