What new species affect the food chain?

Invasive species, such as the Asian Carp in North America or the Cane Toad in Australia, can disrupt food chains by competing with native species for resources and altering predator-prey dynamics. New pathogens and diseases can significantly impact specific species within the food chain and have cascading effects on the entire ecosystem. Climate change-induced range shifts or phenological changes can lead to new interactions between species that alter their roles or positions within the food chain.

The introduction of new species, the emergence of diseases, climate change-driven shifts, and trophic cascades all represent significant factors that can alter and reshape food chains in various ecosystems. Understanding these dynamics is crucial in preserving ecological balance and maintaining the diversity and resilience of natural food webs.
