Answer:
B. Ecosystem boundaries often (usually) match political boundaries
Step-by-step explanation:
Environmental science is the science where natural sciences are used to study the environment and find solutions facing the environment. It also incorporates social sciences in order to understand how the environment and humans interact with one another.
A community of living organisms interacting with the non living elements of a given environment is known as an ecosystem.
The boundary between two adjacent habitats is known as an ecosystem boundary. Political boundaries are made by humans and are not made naturally.
Hence, ecosystem boundaries often (usually) match political boundaries is false.
