Wetlands serve as a resting place for migratory birds and a nursery for many young animals. The microorganisms, plants, and animals that find shelter in the wetlands serve as food for other microorganisms, plants, and animals. Birds feeding in Savannas in St. Lucie County, Florida.

Energy is the ability to do work.
Having energy is very important because it is required by all organisms for life. Energy from the sun is acquired directly by plants. Through the process of photosynthesis , plants convert the sun's energy into carbon-containing compounds. Plants that are not burned or eaten eventually die and slowly decompose. The decomposing plant matter builds up to form carbon-rich deposits called peat.
