Why did Darwin believe that only a small number of offspring survive?

It wasn't exactly that. Darwin believed that species evolved through natural selection. Meaning the individual that's best suited for the environment survives. So for example giraffes. As the food started getting harder and harder to reach only giraffes with longer necks would survive. Hence giraffes have freakishly long necks now

What is Darwin's theory of overpopulation?
The phenomenon of over-population, according to Darwin's theory, starts the whole process of evolutionary transformation of organisms. Overproduction is the main laws of natural selection ,it is the ability of a species to produce far more offspring than can survive. The number of organisms of each species are born into the world, more than the number of them, which can find their own food to survive and leave offspring, yet the number of each species in natural conditions is fairly constant. Therefore, it must be assumed that most of the offspring in each generation dies. If all the descendants of a species to survive and reproduce, then pretty soon they would be supplanted all other forms in the world.
How is it possible that a species that has only one young at a time is equally successful?
(Study Island)The success of a species depends on the number of offspring that survive long enough to reproduce.(Explanation)The success of a species depends on the number of offspring that survive long enough to reproduce, not just the number of offspring produced at a time or even in a lifetime. A penguin who has only one young can devote a lot of time, attention, and care to it, greatly increasing its chances of surviving long enough for it, too, to reproduce. An octopus, on the other hand, usually dies shortly after reproducing. A young octopus has no parent to protect or teach it, so the vast majority of octopi do not survive long enough to reproduce.
What is a jaguar's number of offspring?

Number of offspring in a litter species for penguins?
1 egg
How did Darwin explain the fact that only a small number of offspring of any species survive to reproduce?
Offspring must compete for available resources in order to survive

Why do toads produce large number of eggs?
To ensure that at least a few offspring will survive to become adults
What is Darwin's measure of success in origin of species?
Success in the context of natural selection means reproductive success, or fitness. It refers to the average number of fertile offspring raised by any variant, lineage or population as a whole.
How many offspring do opossums have?
They can have as many as 20, but only about half survive.

Organism usually produce only as many organisms as will survive?
Absolutely not... typically they will produce a multiple more than what will survive in order to maximize survivability... genetically speaking this increases the 'fitness' of the organism. Turtles and other reptiles will produce dozens of offspring only to have a small percentage survive, but reptiles take very little care of their young (the majority of the fates of the offspring are left up to chance and the strengths of individual offspring). Mammals will produce less (typically 1/2 of the number of nipples for feeding is the average birth number at one time). Mammals produce less because they take more care of their offspring and leave less to chance.Spider unfortunately (in this authors humble opinion), have WAY too many offspring! :)Have a great day,Synapse your fingers to the beat,Synaptophyllic
How do you find recombination frequencies on a chromosome?
Recombination frequency = (Recombinant offspring) / (Total offspring) i.e. the recombination frequency is calculated by taking the number of recombinant offspring and dividing it by the total number of offspring.
Average number of offspring for a black bear?
the average offspring of a bear is 2. But the offspring depends on the species.
What does fitness relate to Darwin's theory?
Fitness is generally measured in average number of fertile offspring.
