In which type of symbiosis do both members benefit from their interaction?


a. mutualism
b. parasitism
c. commensalism
d. pathogenesis

Verified step by step guidance

1. Identify the key terms in the question: symbiosis, benefit, interaction.
2. Understand the definition of symbiosis: a close and long-term biological interaction between two different biological organisms.
3. Review the types of symbiosis: mutualism, parasitism, commensalism, and pathogenesis.
4. Define mutualism: a type of symbiosis where both organisms involved benefit from the relationship.
5. Compare the definitions of mutualism, parasitism, commensalism, and pathogenesis to determine which one fits the description of both members benefiting.

Key Concepts

Mutualism

Mutualism is a type of symbiotic relationship where both organisms involved benefit from the interaction. This can include various forms of cooperation, such as nutrient exchange, protection, or enhanced reproductive success. An example of mutualism is the relationship between bees and flowering plants, where bees obtain nectar while helping plants with pollination.

Parasitism

Parasitism is a symbiotic relationship in which one organism, the parasite, benefits at the expense of the other, the host. The parasite derives nutrients and shelter from the host, often harming it in the process. Common examples include ticks feeding on mammals or tapeworms living in the intestines of their hosts.

Commensalism

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed. This interaction can involve one species using another for transportation or habitat without affecting its wellbeing. An example is barnacles attaching to a whale; the barnacles gain mobility and access to food, while the whale remains unaffected.
