Correct option is B
The correct answer is: (B) A close and long-term interaction between different species
Explanation:
In ecology, symbiosis refers to a close and long-term biological interaction between two different species. These species may live together for an extended period and can have positive, negative, or neutral effects on each other. Symbiosis can take various forms, including mutualism (both species benefit), commensalism (one benefits, the other is unaffected), and parasitism (one benefits at the expense of the other).
Information Booster:
- Mutualism: A form of symbiosis where both species benefit from the interaction. For example, bees and flowers – bees get nectar, and flowers get pollinated.
- Commensalism: One species benefits, while the other is neither helped nor harmed. For example, barnacles on a whale – barnacles benefit from being transported to nutrient-rich waters, while the whale is unaffected.
- Parasitism: One species benefits at the expense of the other. An example is ticks on mammals, where ticks feed on the host's blood, harming the host.
- Symbiosis can occur in a variety of ecosystems, from marine environments to terrestrial ecosystems.
Additional Knowledge:
- Photosynthesis: This is the process by which plants produce food using sunlight, carbon dioxide, and water.
- Competition between organisms for resources: This is an ecological interaction where species fight for the same resources (like food or space).
- Random movement of organisms in their habitat: This describes a form of movement or distribution of organisms.
