Common-Core Grade 5 - 5 Identifing ecosystems

Ecosystem are of different types
Grasslands are areas dominated by grasses. They occupy about 20% of the land on the earth surface. Grasslands occur in both in tropical and temperate regions where rainfall is not enough to support the growth of trees.
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.

A producer in an ecosystem is the baseline part of a food chain. Producers include plants, bacteria, algae and phytoplankton. Organisms that eat producers are called consumers, and organisms that consume dead organisms are called decomposers. They all participate in the complex web of an ecosystem.
. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.
Biotic components refer to all living components in an ecosystem.

Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere.19-May-2022
