Symbiotic - co-existing without interference.
Parasitic - co-feeding without destructive predation.
Competition - interaction between organisms or species, in which the fitness of one is lowered by the presence of another.
Predatory - hunter and hunted.
The four types of evidence that support the theory of evolution are fossil records showing transitional forms, similarities in embryology and anatomy across species (homology), biogeography (distribution of species around the world), and genetic evidence such as DNA comparisons that show relationships between different species.
Four ares of social interaction for adolescents include;self centered attitudes, peer relationships, personal identity, and independence and testing boundaries.
These four species are distantly related and share a common ancestor.
James Angus Jenkins has written: 'The cytogenetic relationships of four species of Crepis' -- subject(s): Crepis
The relationship can be more than, equal to, less than or a ratio.
There are four properties of force: gravitation, electromagnetism, the weak interaction, and the strong interaction.
Depending on the species, possums are weaned between four and six months of age.

I'm assuming you mean ecological relationship.An ecological relationship is the relationship between organisms in an ecosystem. There are six ecological relationships in which two are oppositional and four are symbiotic. The oppositional relationships are predation and competition. The symbiotic relationships are mutualism, commensalism, amensalism, and parasitism.
Food webs offer several key benefits: they illustrate the complex interconnections between different species in an ecosystem, highlighting how energy and nutrients flow through various trophic levels. This complexity promotes biodiversity, as it allows for multiple feeding relationships and reduces the risk of ecosystem collapse if one species declines. Additionally, food webs provide insights into ecosystem health and stability, guiding conservation efforts by identifying critical species and relationships. Lastly, they enhance our understanding of ecological dynamics, which can inform sustainable practices in agriculture and resource management.

Command relationships help establish the order of command. The four types of relationships are operational control, assigned command, attached command, and tacon command.
