Understanding Overproduction and Natural Selection

The video explains the concept of overproduction in nature, where species produce more offspring than can survive. This ensures that some individuals reach adulthood despite challenges like predators and competition. Ducks and dandelions are used as examples, illustrating how many offspring are produced and the few that survive to adulthood.

What is the primary reason species produce more offspring than can survive?

• Weather

• Predators

How many seeds does a dandelion typically produce?

• 50

• 500

• 150

• 311

What is the likelihood of all dandelion seeds growing to adulthood?
