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.
Free-living flat worms = carnivores or scavengers
Have digestive cavity, mouth, pharynx
Parasitic Flatworms: = Feed on blood, tissue fluids, or pieces of cells from within a host
We can confirm that the absence of photosynthesis on Earth would cause a mass extinction of most of the species on the planet.
<h3 /><h3>Why would the absence of photosynthesis be so harmful?</h3>
The process of photosynthesis is extremely important as it produces oxygen as a byproduct. The absence of this process on Earth would limit the available oxygen in the atmosphere which would at some point be entirely consumed. From then on, most species on the planet would die out as they require oxygen to live. Most plant species would also die off as they use photosynthesis to sustain life.
Therefore, we can confirm that the absence of photosynthesis on planet Earth could be considered an apocalyptic event as it would cause a near-complete extinction of life on the planet.

Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
<h3>What is Acetylcholine?</h3>
Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.
Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
