Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor.
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants. Then these plants are eaten by animals. Thus oxygen is an important and beneficial by-product of photosynthesis. Oxygen is also very important for the survival of human beings.
It is last time be you’re correct
The magnification power level of the microscope
Animals get carbon by eating plants or by eating other animals.
so the correct answer would be C
The lion eats an herbivore that ate the grass
Plants use carbon dioxide for photosynthesis. By doing so, they remove inorganic carbon from the atmosphere and incorporate it into the plants’ tissues in the form of organic carbon (sugar and starch).
Carbon is returned to an inorganic state in a number of ways. As an animal breathes (respires), it exhales carbon dioxide, returning it back to the atmosphere. When an animal or plant dies, it is broken down by bacteria and fungi and again the carbon is released (this process is called decomposition).
Sometimes, instead of completely decomposing, a plant or animal may be fossilised, leading to its carbon being stored in a rock. After millions of years and under the right conditions, these fossils may turn into fossil fuels (oil, coal and natural gas).
hope this helps!!
