Answer:
True
Explanation:
Methanogens are prokaryotic microbes that produce methane as a by-product of metabolism in anoxic or anaerobic conditions. They are commonly found in the gastro-intestinal parts of ruminants, Marine sediments, and wetlands etc. They are responsible for the methane content released when cows burp/belch and the marsh gas of the wetlands.
Methanogens are strictly anaerobic (they thrive best in a no-oxygen condition) and play a vital ecological role by using up excess hydrogen as an energy source and other products of fermentation released during anaerobic respiration. Due to this, methanogens thrive in an environment which has all electron acceptors e.g. Oxygen, Sulphate, Nitrate etc. removed. This excludes CO2 because methanogens use CO2 as their carbon source.
Answer:
1. Obtaining energy
2. responding to a stimulus
3. reproduction
4. excretion
Explanation:
1. All living organisms require energy for their life processes. This energy is derived from food. The food we eat contains biomolecules that store energy. The energy stored by these food molecules is released by a process called RESPIRATION. Image 1 shows a cat trying to obtain energy by feeding. The food will eventually be broken down to release energy.
2. Stimulus is any thing (whether internal or external) that causes a change in an organism. In image 2, a man is responding to a sudden change in his back, which is pain.
3. Reproduction is a characteristics of living organisms that involves the production of young ones. Image 3 depicts two cells undergoing fertilization (fusion of nuclei) to produce a new cell. In turn, the cell divides again to form two gametes. The cycle continues like that.
4. Excretion is the removal of waste products from a cell. According to Image 4, the cell allows a food particle in and releases the waste contents out of the cell.
