ALL animals make use of other animals and organisms for food. They are heterotrophic so they have to get energy elsewhere.

ALL animals are capable of motion at some stage of their lives.

Animals developed specialized cells and tissues that are advanced and complex.

And because all animals eat I would assume they all digest the food they ingest. Other than parasites who don't really digest their food.

You are given a task to produce massive quantities of Protein A from soybean so that the Protein A can be added to a mixture to
kiruha [24]

Producing 100 kg of protein A requires calculating the necessary amount of soy, calculating the necessary inputs, looking for related information, and supervising the process.

To produce 100 kg of protein A with soybeans, I must look for information related to the cultivation of soybeans, what is the protein concentration in a soybean, and other aspects necessary for its maintenance and harvest.

In this search, I find that soy has a protein concentration of 50% or higher, so if I have to get 100 kg of protein, I must get at least 200 kg of soy.

So I grow some soybean plants in pots inside my house and I harvest their grains until I complete 200kg, supervising the whole process so that the plant does not suffer any disease or problem.
