elena55 [62]
The difference between the two students that we know of is that they used a different meter stick. So the difference would be best attributed to  the different tools they used.

Note, this is quite a huge difference. It's likely that one of the sticks, or both, are quite defect.

Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms .
Rus_ich [418]
<span>The characteristics that scientists used to classify living organisms into six kingdoms include the following:
1. Cell type: living organisms are classified into prokaryotes and eukaryotes based on the presence of nucleus and distinct arrangement of the organelles in their cells.

2. Mobility: living organisms are categorized into kingdoms based on their ability or inability to move about.

 3. Cell structure: the cells structure was used to divide living organisms into plants and animals. Those living organisms that have cell wall are classified as plants while those who do not have cell wall are classified as animals.

4. Number of cells: living organisms that are made up of only one cell are classified as unicellular while those with many cells are termed multi cellular.

 5. Reproduction method: living organisms are classified based on whether they reproduce sexually or asexually.

6. Manner of obtaining energy: living organisms that can prouduce their own food are called autotrophs while those that can not produce their own foood are termed heterotrophs. Plants are essentially categorised as autotrophs while animals are described as heterotrophs.</span>

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.
