Ecology

phytoplankton

Biology; Ecology

Tiny, free-floating, photosynthetic organisms in aquatic systems. They include diatoms, desmids, and dinoflagellates.

absorption

Biology; Ecology

The passage of water and nutrients through cell membranes instead of by direct ingestion. Also refers to how objects convert the solar radiation they receive into heat.

limnology

Biology; Ecology

The study of river system ecology and life.

desiccation

Biology; Ecology

The process of drying out. In biology, moisture loss in organisms.

upwelling

Biology; Ecology

The raising of benthic nutrients to the surface waters. This occurs in regions where the flow of water brings currents of differing temperatures together, and increases productivity of the ecosystem.

nitrogen fixation

Biology; Ecology

The conversion of gaseous nitrogen into a form usable by plants. Ususally by bacteria.

ingestion

Biology; Ecology

The intake of water or food particles by "swallowing" them, taking them into the body cavity or into a vacuole. Contrast with absorption.
