Give at least three facts autotrophs and heterotrophs on earth are true?
White raven [17]

Answer:

  • Autotrophs are usually defined as those that can prepare their own food by carrying out the process of photosynthesis, but heterotrophs cannot prepare their own food and are directly dependent on the autotrophs for food. Examples of autotrophs are plants and trees, and examples of heterotrophs are animals and human beings.
  • Autotrophs are the lowest organisms in the trophic level, where they produce the food for the consumers (heterotrophs). On the other hand, the heterotrophs lie above the autotrophs and when they consume their food, they obtain only 10% of the energy, and the remaining energy is released into the environment.
  • Autotrophs can make organic substances by the use of inorganic molecules, but heterotrophs cannot make these substances. They are only dependent on the molecules prepared by these autotrophs.

Thus, these are three of the facts regarding autotrophs and heterotrophs existing on earth that are true.

Andrej [43]
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also for efficient for these smaller and miniscule cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy.
