Relationships can be obligate, meaning that one or both of the symbionts entirely depend on The other is not helped but is not harmed or damaged from the relationship.

The bird oxpecker lives on the rhino and removes all bugs and parasites on the animal skin by eating them. The Rhino provides the bird with food and in return, the bugs removed from the skin of the rhino.

Both rhino and the oxpecker is benefited. Types of Mutualism There are five types of Mutualism. Obligate mutualism In obligate mutualism the relationship between two species, in which both are completely dependent on each other. Most of the symbioses and some non-symbiotic are the best examples of obligate mutualism For example Yucca plant and the moth. The yucca plant, the habitat of dry and arid climate of the southwestern United States. The flower of the yucca plant relies on the moth for the pollination process.

In turn, the moth is benefited by laying its eggs on the flower and feeding the larvae with the seeds.

For example Honeybees and plants. For example The cows and the bacteria. The bacteria present the in the rumens of cows helps in digesting plants cellulose. In reverse bacteria gets a food and warm environment, which is required for their growth and development. In defensive mutualism, one partner receives food and shelter and in return, it helps the partner by defending against the herbivores or predators or parasites.

For example The aphids and the ants.

Examples of mutualism

The aphids produce honeydew to the ants, which is carried to their nests at night for protecting them from the predators and escort. These aphids are carried back to the plant the next morning. In dispersive mutualism, one partner receives food in return for helping flower in transferring their pollen.

For example Honeybees and the Plants. Symbiosis refers to a close relationship in which one or both organisms obtain a benefit. The organism that is eaten is called the prey.

  • Commensalism
  • Competition & Predation
  • Symbiotic relationships in nature

Examples of predation are owls that eat mice, and lions that eat gazelles. Competition is when individuals or populations compete for the same resource, and can occur within or between species. When organisms compete for a resource such as food or building materials it is called consumptive or exploitative competition.

Mutualism, Commensalism, Parasitism, Amensalism, Predation & Competition

When they compete for territory, it is called interference competition. When they compete for new territory by arriving there first, it is called preemptive competition.

An example is lions and hyenas that compete for prey.

Commensalism Commensalism is a relationship in which one organism benefits while the other is neither helped nor harmed. Examples are barnacles that grow on whales and other marine animals. The whale gains no benefit from the barnacle, but the barnacles gain mobility, which helps them evade predators, and are exposed to more diverse feeding opportunities. There are four basic types of commensal relationships.

Chemical commensalism occurs when one bacteria produces a chemical that sustains another bacteria. Inquilinism is when one organism lives in the nest, burrow, or dwelling place of another species.

Metabiosis is commensalism in which one species is dependent on the other for survival. Phoresy is when one organism temporarily attaches to another organism for the purposes of transportation.

Parasitism Parasitism is a relationship in which one organism benefits and the other organism is harmed, but not always killed. The organism that benefits is called the parasite, and the one that is harmed is the host.
