In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, salinity, precipitation, altitude, minerals, tides, rain ...
9. Cold temperatures and decreased light availability result in lower rates of primary production and decreased phytoplankton populations. 10. Reproduction in zooplankton decreases due to lower temperatures and less prey. The PEG model presents an idealized version of this succession pattern, while natural systems are known for their variation. [2]
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
Factors such as body weight at 10 years old and maternal smoking around birth were shown to have an impact 30 to 80 years later. Environmental exposures also had a greater impact on chronic lung ...
Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.
The Summary. A NASA spacecraft brought samples from the asteroid Bennu back to Earth in 2023. The first in-depth analyses of that material have revealed organic molecules, including building ...
The Gaia hypothesis (/ ˈ ɡ aɪ. ə /), also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating complex system that helps to maintain and perpetuate the conditions for life on the planet.
Melania Trump has returned to the White House alongside her husband, President Donald Trump. Take a look at the life of America's first lady, who went from a model to a powerful world figure.
