FAQs on Symbiotic Relationship Video Lecture - Science Class 7
| 1. What is a symbiotic relationship? |  |
Ans. A symbiotic relationship is a close and long-term interaction between two different species in an ecosystem. It can be mutually beneficial, where both species benefit, or it can be parasitic or predatory, where one species benefits at the expense of the other.
| 2. What are the different types of symbiotic relationships? | |
Ans. There are three main types of symbiotic relationships: mutualism, commensalism, and parasitism. In mutualism, both species benefit from the interaction. In commensalism, one species benefits while the other is unaffected. In parasitism, one species benefits while the other is harmed.
| 3. Can you provide an example of mutualistic symbiotic relationship? | |
Ans. An example of mutualistic symbiotic relationship is the partnership between bees and flowers. Bees collect nectar from flowers as a food source, while inadvertently pollinating the flowers in the process. The bees benefit from the nectar, and the flowers benefit from the pollination, leading to successful reproduction.
| 4. How does parasitic symbiotic relationship work? | |
Ans. In a parasitic symbiotic relationship, one species, the parasite, benefits at the expense of the other species, the host. The parasite typically lives inside or on the host, deriving nutrients and resources from it. This often harms the host, weakening it or causing disease.
| 5. What is an example of commensalism? | |
Ans. An example of commensalism is the relationship between cattle egrets and grazing animals, such as cattle or buffalo. The egrets feed on insects stirred up by the movement of the grazing animals, benefiting from the easy access to food. The grazing animals are unaffected by the presence of the egrets.
