How do organisms respire?

Answer 1

They dont

Answer 2

How? Breathe in, breathe out :)

Many fungi (perhaps all?) are capable of burning sugars just like animals, using oxygen and producing carbon dioxide and water as waste products. Obviously they don't have lungs and complex circulatory systems, but the chemistry is the same.

Also like animals, some (all?) fungi are capable of anaerobic "respiration" without atmospheric oxygen. Carbon dioxide is still produced, but also other more complex waste products. Where these waste products are toxic in animals and limit the use of anaerobic metabolism, in fungi they can be beneficial. One example is the production of alcohol by anaerobic respiration of yeast. This was perhaps originally a poison intended to eliminate other fungi. The structures of yeasts make them more able to get rid of this type of waste product and so be more flexible about which metabolism they use.

Answer 3

No, Fungi do not breathe. "Breathing" is defined as drawing air into lungs and expelling it thereby transforming oxygen into carbon dioxide. Not all living things need to do this to survive. Plants and fungi do not inhale and exhale.

Answer 4

Bacteria are small, single-cell organisms that are both beneficial and harmful to human beings. Some forms of bacteria help us to live, such as those that help to break down food in our intestines. Other forms, such as the bacteria that causes the Bubonic Plague, can kill a person if left untreated. There are many different types of bacteria and they respire using different methods. The two primary methods of bacterial respiration are aerobic respiration and anaerobic respiration.

Answer 5

they breathe in oxygen and release carbon dioxide

Answer 6

Fungi have hair-like structures called hyphae that absorb oxygen. They absorb the oxygen from the microscopic pockets in the soil.

Answer 7

through the holes in the stem, connected to the ground made of dirt and earth and rock and lava and organisms

Answer 8

through their feet.
