Tenancy



Bromeliad and Acacia: Tenant Relationship

What is - meaning

Tenancy is an ecological relationship in which one species (animal or plant, called a tenant) extracts advantages (benefits) from another species for protection, transportation or support without causing harm or benefits to this second (host). Therefore, it is a harmonic interspecific relationship (between different species) (none of them are harmed from the relationship), although only one benefits.

Epiphytism

Epiphytism is a type of nihilism. In this case, epiphyte plants (bromeliads and orchids, for example), seek support in the tree trunk to develop, but without removing nutrients from the trees. Epiphytes use trees only for support.

Examples of tenancy:

- Bromeliad and orchid plants use tree trunks to support their development.

- Gar when in danger (chased by a predator) enters the digestive tract of the sea cucumber (echinoderm) for protection. Fish (tenant) benefits, but the echinoderm (host) is not harmed in this ecological relationship.

- Remora are fish that have a suction cup on the top of the head. They use this suction cup to attach themselves to the bottom of the shark's body. In this way, rémoras (tenants) are able to obtain fast transportation with sharks (hosts) without harming them.
