Answer:
The 3 limiting factors that might drive competition within a single species is the food, availability of mates, disease, and shelter (biotic factors) and temperature, climate, sunlight, rainfall, natural disasters, and pollution (abiotic factors).
Explanation:
These factors limit the size of populations. As a population grows, there is more and more competition for the limited resources that Earth provides.
Biotic factors are living things that affect the ecosystem (like when we manually burn/chop down trees and destroy habitats of animals who used to live there).
Abiotic factors are non-living things (natural causes) that affect the ecosystem (like climate change causing the melting of glaciers and mass burning of trees (aka forest fire))
