This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
A closed ecological system for an entire planet is called an ecosphere. [2] [3]Man-made closed ecological systems which were created to sustain human life include Biosphere 2, MELiSSA, and the BIOS-1, BIOS-2, and BIOS-3 projects.
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
Biosphere 2, with upgraded solar panels in foreground, sits on a sprawling 40-acre (16-hectare) science campus that is open to the public. The Biosphere 2 project was launched in 1984 by businessman and billionaire philanthropist Ed Bass and systems ecologist John P. Allen, with Bass providing US$150 million in funding until 1991. [7]
Vernadsky defined ecology as the science of the biosphere. It is an interdisciplinary concept for integrating astronomy , geophysics , meteorology , biogeography , evolution , geology , geochemistry , hydrology and, generally speaking, all life and Earth sciences.
Halophiles (organisms that thrive in highly salty environments) and hyperthermophiles (organisms that thrive in extremely hot environments) are examples of Archaea. [1] Archaea are relatively small. They range from 0.1 μm to 15 μm diameter and up to 200 μm long, about the size of bacteria and the mitochondria found in eukaryotic cells.
The term 'heat dome' has gained prominence recently as climate change, El Niño and other variables have warmed global temperatures and shifted weather patterns. Heat wave or heat dome? Yes, there ...
For example, matter from terrestrial autotrophs are both biotic and accessible to other organisms whereas the matter in rocks and minerals are abiotic and inaccessible. A biogeochemical cycle is a pathway by which specific elements of matter are turned over or moved through the biotic ( biosphere ) and the abiotic ( lithosphere , atmosphere ...
