Habitat and Ecosystem
When
you think of life in Greenwich Bay, you may think of the things you see
the most often—animals like fish, crabs, quahogs, 
and
maybe a few different kinds of plants. But life in Greenwich Bay is much
more complex—ranging from microscopic plants, animals, and bacteria
to humans, or to the occasional large visitor such as a seal.
An ecosystem involves more than living things. All life in Greenwich Bay dependson, or is at least affected by, nonliving parts of the environment. These include oxygen, nutrients, and salt—even the water itself. So the bay's ecosystem includes these nonliving things, all the living things in the bay, and all the ways they interact with each other.
To begin to understand Greenwich Bay as an ecosystem, it may be helpful to start with one animal, and look at how it fits into the ecosystem. Meet the menhaden, a common species of fish in Greenwich Bay. SPECIES SPOTLIGHT
