Answer:
Large areas of the earth with similar climate and ecosystems are called biomes.
Explanation:
Biomes are defined as areas of the planet with common characteristics, such as animal and plant species, as well as climate, which is why it is called a bioclimatic landscape.
When a relationship is established between an ecosystem —with all its biotic and abiotic components— and the climate in a given area, reference is made to a biome. Consequently, a <u>biome represents large areas of land with similar geographical, climatic and biological conditions</u>.
The other options are not correct because:
- <u><em>Communities</em></u><em> are groups of individuals with common characteristics.
</em>
- <u><em>Populations</em></u><em> are individuals of the same species that occupy a certain space in a certain time.
</em>
- <u><em>Organisms</em></u><em> are synonymous with living beings.</em>

The first person to discover and accurately describe microbes was the amateur microscopist Antony van Leeuwenhoek (1632 - 1723) of Delft, Holland. He earned his living as a draper and haberdasher but spent much of his spare time constructing simple microscopes composed of double convex glass lenses held between two silver plates. </span>His microscopes could magnify 50 to 300 times and he may have illuminated his liquid specimens by placing them between two pieces of glass and shining light on them at a 45 degree angle to the specimen plane.
From<span> 1673, He sent detailed letters describing his discoveries to the Royal Society of London and it is clear from his descriptions that he saw both protozoa and bacteria.</span>
