FAQs on Ecosystem: Interdependence in Nature - 1 Class 6 Worksheet Science

1. What is an ecosystem?
Ans. An ecosystem is a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their non-living environment. It includes both the biotic (living) and abiotic (non-living) components and their interactions.
2. How do living organisms depend on each other in an ecosystem?
Ans. Living organisms in an ecosystem depend on each other for various reasons. For example, plants produce oxygen through photosynthesis, which is essential for animals to breathe. Animals, in turn, help in the pollination of plants and dispersal of seeds. Some organisms also rely on each other for food, such as the predator-prey relationship. Overall, the interdependence of different organisms ensures the balance and sustainability of the ecosystem.
3. What are some examples of interdependence in nature?
Ans. Some examples of interdependence in nature include the relationship between bees and flowers. Bees depend on the nectar and pollen from flowers for food, while flowers rely on bees for pollination. Another example is the symbiotic relationship between certain fish species and cleaner fish. The cleaner fish feed on parasites and dead skin of larger fish, providing them with a cleaning service. These are just a few examples of the countless interdependent relationships found in nature.
4. How does human activity affect interdependence in ecosystems?
Ans. Human activity can have both positive and negative effects on interdependence in ecosystems. For instance, deforestation disrupts the habitat of many species, leading to a loss of biodiversity and affecting the interdependent relationships within the ecosystem. On the other hand, conservation efforts and sustainable practices can help protect and restore ecosystems, preserving the interdependence of the organisms within them.
5. How can we promote the interdependence of nature for a sustainable future?
Ans. To promote the interdependence of nature for a sustainable future, we can take several actions. These include practicing responsible consumption, reducing waste, supporting conservation efforts, and using renewable energy sources. Additionally, educating ourselves and others about the importance of interdependence in nature can help create a collective understanding and commitment to preserving and restoring ecosystems.
