The three examples of biotic factors from the options provided are:

1. Rotting log: This is considered a biotic factor because it was once part of a living organism (a tree). Even though it's no longer alive, it still plays a role in the ecosystem by providing habitat and food for other organisms.

2. Dead leaves: Similar to the rotting log, dead leaves were once part of a living organism and continue to play a role in the ecosystem after they've fallen off the tree. They provide food and shelter for many organisms and contribute to the nutrient cycle when they decompose.

3. Bacteria: These are microscopic living organisms. They play a crucial role in ecosystems, helping with processes like decomposition and nutrient cycling. They can also have relationships with other organisms, such as helping with digestion in animals or forming symbiotic relationships with plants.
