Ecology (from οἶκος, "house", or "environment"; -λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment.
An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone.
An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil.
An ecotone is a transition area between two biomes.
Fauna is all of the animal life of any particular region or time.
Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life.

Geography (from Greek γεωγραφία, geographia, literally "earth description") is a field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth.
Geology (from the Ancient Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.
Geomorphology (from Ancient Greek: γῆ, gê, "earth"; μορφή, morphḗ, "form"; and λόγος, lógos, "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface.

The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes.
In ecology, a habitat is the type of natural environment in which a particular species of organism lives.
The Himalayas, or Himalaya, form a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau.
Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability.
A lake is an area filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake.
A landform is a natural feature of the solid surface of the Earth or other planetary body.
Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems.
