Forms of Struggle for Existence and Examples

The struggle for existence refers to the competition and challenges faced by organisms in their quest for survival. There are several forms of struggle for existence, including intraspecific competition (within a species), interspecific competition (between different species), and adaptation to unfavorable environmental conditions. Let's match the examples with the corresponding forms of struggle for existence:

1) Intraspecific competition - competition within a species - Example: Competition among crows for nesting sites [[1]]

2) Interspecific competition - competition between different species - Example: Birds spreading plant seeds [[2]]

3) Adaptation to unfavorable environmental conditions - Example: - Migration of swallows to warmer regions in autumn [[3]] - Symbiosis between fungi and plant roots [[4]] - Increase in the density of fur in animals during winter [[5]] - Protection of bison calves by adult bison [[6]]
