which organisms is connected to all other organisms in a food web

None of the organisms in a food web are directly connected to all other organisms. However, there are some species known as keystone species that have a very significant impact on the food web, and their removal could greatly alter the dynamics of the ecosystem. Examples of keystone species include sea otters, wolves, and sharks.
In a food web, there isn't any particular organism that is automatically connected to all other organisms. A food web is a complex network of interactions showing the flow of energy and the transfer of nutrients between different species in an ecosystem.
Typically, in a food web, each organism is connected to multiple other organisms through the food chains they are a part of. An organism's connections depend on its role as a predator, prey, or both. For example, a top predator, such as a lion in a savannah ecosystem, might be connected to multiple prey species, while some organisms, like decomposers or scavengers, can interact with almost any other organism as they break down dead organic matter.
Understanding the connections in a specific food web usually involves studying the feeding relationships, energy flow, and ecological interactions within that particular ecosystem. Scientists use field observations, studies of diet preferences, and sometimes even experiments, such as stable isotope analysis, to determine how different organisms are connected in a food web.
Therefore, it is not accurate to say that there is a single organism that is connected to all others in a food web. The connections within a food web are intricate and can vary depending on the specific ecosystem and its dynamics.
