Question

What are biotic and abiotic factors that affect dolphins survival and how?

Answer 1

Abioitic means nonliving-water temp,water salinity, water pressure,turbidity of water pollution,weather.

Biotic means living-condition of it's food source , condition of it's predators,other living species sharing in that biome/habitat (presence of exotic species).

Answer 2

abiotic factors are things like minerals, and water.  Biotic factors are living things (plants and animals).  I think you should be able to figure this out.  Think about what a dolphin needs to survive.
