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.

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.
Evolution is the gradual process of change and adaptation in living organisms over time, leading to the development of new species from existing ones.

Changes in the environment can cause some organisms to have to find a new way of living. Others might need to find a new source of food, or move to an area where they can live their lives as they were before. Changes in temperature is a major climate changer. It can make most animals migrate to a completely different area of the world, just by a little difference in the temperature. Changes in the environment can be devastating to some organisms and good to others. It can take away sources of food and water, or it can give new ones to the organisms that so desperately need them to survive.
