Which is a difference between abiotic and biotic factors?

• abiotic factors are plants and biotic factors are animals
• biotic factors are plants and abiotic factors are animals
• abiotic factors are all living things and biotic factors are all nonliving things
• abiotic factors are all nonliving things and biotic factors are all living things

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
• Because it’s better to have only one variation of each species.
• Because it better to only have a few species on Earth.
• Honestly, I have no idea what biodiversity is!
