Question

How are living organisms in an ecosystem linked?

by their size

by what they eat

by their species

by how they breathe

Answer 1

Living organisms in an ecosystem are primarily linked by **what they eat**. This connection forms the basis of food webs and food chains, illustrating how energy and nutrients flow through different levels of the ecosystem. Organisms are categorized as producers, consumers, and decomposers based on their roles in the food system, directly impacting their interactions and relationships within the ecosystem.

While size, species, and how organisms breathe can influence interactions, the fundamental link in the ecosystem is based on trophic relationships and feeding habits.
