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>

Through which process are food resources, such as plants and animals, renewed?
lapo4ka [179]

The correct answer is D. Life cycles.

Explanation

The life cycle is a term used to refer to the set of processes or stages in the life of living organisms on Earth that preserve the balance of ecosystems. In this, four fundamental processes are to be born, to grow, to reproduce and to die, at the same time all of these stages allow the renewal of organisms such as plants or animals, this can be explained as stages such as reproduction lead to new organisms being born, similarly as organisms die these are replaced by organism that have just started the life cycle. So, the correct answer is D. Life cycles.
