Which will reduce competition within a species’ population?

1. Increase in available resources: If there is an increase in food, water, shelter, or other resources that the species relies on, it can reduce competition as individuals have more access to what they need to survive and reproduce.

2. Migration or dispersal: If some individuals of a species move to different areas or habitats, it can reduce competition in the original population as there are fewer individuals competing for resources in a particular area.

3. Decline in population size: If a species experiences a decrease in population size due to factors such as predation, disease, or habitat destruction, competition within the population may decrease as there are fewer individuals vying for limited resources.

4. Changes in behavior: If individuals within a species alter their behavior, such as becoming more territorial or forming social hierarchies, it can help reduce direct competition for resources within the population.
