Reasons for Interdependence between Plants and Animals:
1. Oxygen-Carbon Dioxide Exchange: Plants produce oxygen for animals, while animals produce carbon dioxide used by plants for photosynthesis.
2. Food Chain: Plants are food sources for herbivores, which in turn become prey for carnivores, forming interconnected food chains.
3. Pollination and Seed Dispersal: Animals aid in pollination and seed dispersal, facilitating plant reproduction and growth.
4. Shelter and Habitat: Plants provide shelter and habitat for animals, serving as crucial components of their ecosystems.

This interdependence ensures the balance and sustainability of ecosystems where plants and animals coexist.
