How do all animals affect nature and land?

All animals play crucial roles in ecosystems by contributing to processes such as pollination, seed dispersal, and nutrient cycling. Herbivores help shape plant communities and maintain grasslands, while predators regulate prey populations, preventing overgrazing. Decomposers, such as fungi and scavengers, break down organic matter, enriching the soil and promoting plant growth. Thus, the interactions among animal species and their environments significantly influence biodiversity and the overall health of ecosystems.
