Bacteria in general grow optimally when the pH is around 7 (5-9 let's say). That is not to say that there are not bacteria that grow in extremely acidic conditions, like in our stomach, or others in extremely basic conditions, like the conditions near volcanoes. Nonetheless, bacteria that grow in food prefer acidic environments over basic ones and usually cannot tolerate the acidity of fruits which is around 4 pH for the most acid ones. For example, stuff like milk and bread that have a pH from 5-6 are prime examples of food where bacteria would thrive. Thus, the correct answer would be b.
Answer:
While epidermal tissue mediates most of the interactions between a plant and its environment, ground tissue conducts the basic functions of photosynthesis, food storage, and support.

<h3>Coral reefs, seaweed and forest biome</h3>
Coral reefs are fundamental for protecting wildlife in marine ecosystems.
Seaweed is a common plant in the Euphotic Zone (Sunlight Zone, also called Epipelagic Zone), along with algae and phytoplankton.
Temperate broadleaf forests are represented by areas with marked warm and cool seasons that show moderate annual average temperatures (3 °C to 25 °C).
Examples of producers in a temperate broadleaf forest may be Eucalyptus species, whereas consumers may include, for example, elk, etc.
