Why is cross pollination more widespread than self pollination even though it is more chance based and needs more plant energy expenditure?

Explanation

### Step-by-Step Solution:

- Pollination is the transfer of pollen from the anther (male part) to the stigma (female part) of a flower. It can occur in two ways: self-pollination and cross-pollination.
