Temperature Is light abiotic? The abiotic factors are only sunlight, temperature, and water

I think it's a simple but profound question.

The reason for this is that we can say with certainty that temperature and light are abiotic factors.

It's profound, because the question goes a little further and becomes: What is a living thing? In philosophy, there are similar questions: What is life? This problem has not been and is difficult to solve completely.

Biology is the discipline that is closest to this problem. The answer it gives: living things are all living things. In fact, this definition is meaningless, it is entirely something that biologists have added for the sake of the refinement of the discipline, and it does not solve the problem - it does not define the boundary between living and non-living things.

Now, based on the existing scientific results, people have proposed some common characteristics of organisms that have been discovered to distinguish living things from non-living things, such as: complete structure, metabolism, growth and development, genetic variation, stress and adaptability. But these properties do not include all organisms that are now recognized, such as viruses.

Prion is a macromolecular protein, it does not have typical metabolism, growth and development, stress, etc., and when it does not invade some living organisms, it does not reflect the characteristics of life, in other words, "it can die or live", as long as the structure is not destroyed when "dead", the discovery of viruses is a challenge to the definition of life.

For every living being, everything around it is its environment. There are many environmental factors, and by their nature, they can be divided into abiotic and biotic factors. Abiotic factors include sunlight, temperature, water, atmosphere, soil, etc., and biotic factors include other organisms related to such organisms.

Obviously not, it's weird for you to ask.

Non-living things are inanimate substances, but temperature is only a unit of measurement that people themselves prescribe; And the nature of light is not yet understood, and its nature can be understood in middle and high school physics. They can't be considered material at all, so they can't talk about non-living things.

Abiotic factors are not just sunlight, temperature, and water. There is also a suitable temperature, a suitable humidity and a certain living space.

These are all environmental factors that affect the survival of organisms, and the basic conditions provided by the biosphere for the survival of organisms are: nutrients, sunlight, air and water, suitable temperature and a certain living space.

These are the knowledge points of junior high school biology, the most important thing to learn biology is not only to understand, but also to add a certain amount of memorization, because most of the junior high school biology is still based on words, learning is basic biological knowledge, but also for learning the basic knowledge of high school biology, as long as you understand more, think diligently, plus a certain amount of memorization, you will definitely be able to learn this subject well.

Hope it helps

Abiotic factors that affect the life of living organisms refer to inorganic factors. Inorganic factors mainly include sunlight, temperature, water, pH value, carbon dioxide concentration, mineral factors, etc.

Sunlight is the source of energy and heat for the biosphere. It plays a decisive role in the distribution of green plants on the planet! Long-day plants such as wheat and rape can only bloom in spring; Short-day plants such as chrysanthemums can only bloom in autumn.

Temperature directly affects the metabolism of organisms and is one of the important factors that determine the distribution of organisms. The seasonal migration of marine fish is caused by changes in water temperature.

Water is a necessity for the activities of life. The distribution of water on land determines the appearance of terrestrial life. For example, the morphology of plants such as cacti in arid areas, and the amount of mineral nutrients affect the yield of crops in agricultural areas.

In any case, there can not be only one abiotic cause acting on the organism of the organism, but a combination of factors at the same time, and the change of any one of these factors will affect the survival and reproduction of the organism.

Temperature affects a variety of organisms. For example, resistance to the head: affects the survival of organisms (animals survive at 2 50 degrees); Affects the distribution of plants:

Southern mandarin, northern pear, cold coniferous forest, hot broad-leaved forest; It affects the morphology of animals (polar foxes and desert foxes) and their habits (hibernation and summer hibernation of animals).

It's good to pick one and write it, don't write it all.

pH value, carbon dioxide concentration, mineral factors, oxygen concentration, soil (plants), etc.
