New organisms can alter food webs by introducing new interactions among species, which can shift predator-prey dynamics and competition for resources. For example, an invasive species might outcompete native species for food, leading to declines in those populations and affecting organisms that rely on them. Additionally, new organisms can provide new food sources or niches, potentially enhancing biodiversity or disrupting existing relationships within the ecosystem. Overall, these changes can ripple through the food web, impacting ecosystem stability and functioning.

Primary succession creates new habitats, allowing for the establishment of diverse plant and animal species in an ecosystem. This increases the variety of organisms available as food sources, which in turn can enhance the complexity and stability of food chains and food webs within the ecosystem.
Change can benefit other organisms in the environment by creating new opportunities for adaptation and evolution. It can lead to the emergence of new food sources, habitats, or niches that other organisms can exploit to survive and thrive. Additionally, change can help maintain biodiversity by preventing the dominance of a single species and promoting the coexistence of multiple species in an ecosystem.
As populations of organisms change, it can lead to shifts in biodiversity, ecosystem dynamics, and species interactions. Changes may result from factors like environmental shifts, resource availability, or human activities, which can influence population sizes and genetic diversity. These alterations can also affect food webs and ecosystem services, potentially leading to the emergence of new species or the extinction of others. Overall, such changes can significantly impact ecological balance and resilience.

Biotic.
You have to change the food gradually by mixing the original in with the new food. You then add more and more of the new food until it's all of the new food. By then your puppy's digestive system has adjusted to the new food. When you change foods all at once, it upsets the digestive system.
If you added one or more organisms to a food web, it would be unbalanced for a time and then a new equilibrium would be reached that might or might not include the organisms that were added.
Change of organisms over an extended period of time is known as evolution. Evolution is the process by which populations of organisms change over generations through genetic variation, natural selection, and other mechanisms, leading to the emergence of new species and the diversity of life on Earth.
Creating new competition for food can lead to extinction by disrupting established ecosystems and food webs. When a new species is introduced, it may outcompete native species for resources, leading to a decline in their populations. This can cause a cascading effect, as the loss of one species can impact others that rely on it for food or ecological balance. Over time, this competition can result in the extinction of native species unable to adapt to the new pressures.
Evolution is the gradual process of change and adaptation in living organisms over time, leading to the development of new species from existing ones.
