Symbiosis Types: Which One is It Worksheet Answer

Understanding Symbiosis: A Guide to Types and Relationships

Symbiosis is a fascinating phenomenon in the natural world where different species interact and coexist in unique ways. These interactions can be mutually beneficial, neutral, or even detrimental to one or both parties involved. In this article, we will delve into the three main types of symbiosis: mutualism, commensalism, and parasitism.

What is Symbiosis?

Symbiosis is a Greek term meaning “living together.” It describes the complex relationships between different species that share a common environment. Symbiotic relationships can be found in various ecosystems, including forests, oceans, and even within the human body.

Types of Symbiosis

There are three primary types of symbiosis: mutualism, commensalism, and parasitism. Each type is characterized by the level of benefit or harm caused to the participating species.

Mutualism

Mutualism is a symbiotic relationship where both species benefit from each other. This type of relationship is often seen in nature, where species work together to achieve a common goal.

• Example: Clownfish and sea anemones. Clownfish live among the tentacles of the sea anemone, which would be deadly to most other fish due to the anemone’s stinging cells. But the clownfish has a special mucus on its skin that protects it from the anemone’s sting. In return, the clownfish helps to keep the anemone clean and free of parasites.

• Example: Oxpeckers and rhinoceros. Oxpeckers are small birds that land on the backs of rhinoceroses and feed on ticks, fleas, and other parasites that live on the rhino’s skin. The rhino benefits from the cleaning service, while the oxpecker gets a meal.

Commensalism

Commensalism is a symbiotic relationship where one species benefits and the other is not affected.

• Example: Remora fish and sharks. Remora fish attach themselves to the bodies of sharks and feed on the leftover food particles from the shark’s meals. The shark is not affected by the presence of the remora fish.

• Example: Orchids and trees. Some species of orchids grow on the branches of trees, using the tree as a support. The orchid benefits from the relationship, while the tree is not affected.

Parasitism

Parasitism is a symbiotic relationship where one species benefits and the other is harmed.

• Example: Tapeworms and humans. Tapeworms are parasites that live in the digestive systems of humans and feed on the nutrients that the human body absorbs. The human host is harmed by the presence of the tapeworm.

• Example: Mosquitoes and humans. Female mosquitoes feed on the blood of humans, which can transmit diseases like malaria and Zika virus. The human is harmed by the mosquito’s bite, while the mosquito benefits from the nutrient-rich blood.
