• All plants and animals on earth engage in a process called respiration.
• Respiration combines oxygen and the food created during photosynthesis to produce usable energy. 
• One of the byproducts of respiration is CO2,  if plants stop to take up CO2 and stop releasing O2, then plants will stop to convert sunlight into carbohydrates, and die.
• The death of autotrophs would lead to a chain reaction to the death of all higher-order organisms, Hence, Plants and animals help in maintaining the balance of Oxygen and carbon dioxide.

•  The death of autotrophs would lead to a chain reaction to the death of all higher-order organisms. Hence, Animals will die from the lack of oxygen if plants stop releasing oxygen into the atmosphere.

• Respiration is the movement of oxygen from the outside environment to the cells within tissues and the transport of carbon dioxide in the opposite direction.
•  During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. 
• The energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). Hence, The energy releasing process in living organisms is respiration.

Physiological respiration is the complete process of respiration which includes physical and biochemical pathway. In physical pathway, there is an exchange of gasses that takes place with the help of respiratory organ i.e., lungs. In biochemical pathway, cells are involved where oxidation of food i.e. glucose takes place in mitochondria and cytoplasm in the presence of several respiratory enzymes. 

Fish brought out of water die due to inability to respire. Fish gills are specialized for extracting oxygen from water and cannot effectively extract oxygen from air. The gills collapse and dry out outside water, making gas exchange impossible.

Root caps are the growing part of the roots present at the tips of the roots and are formed by parenchymal cells. Rhizomorphs also have a root cap like structure and hence the first statement is incorrect. So the right answer is option 'Rhizomorph do not have root cap like structure'.

Plant mushroom get its food from dead and decaying plants. In short, they are saprophytes. Plants are green because they contain chlorophyll, which helps them with photosynthesis, the process of turning sunlight into food. Mushrooms are not green and they contain no chlorophyll. Therefore, they cannot photosynthesize. Mushrooms obtain their food by metabolizing dead or decaying organic matter, such as dead plants on the ground. Tiny filaments called as hyphae absorb the nutrients from the dead matter. Mushrooms are made up of hyphae filaments and a mass of hyphae is called as a mycelium. This is why, you often see mushrooms growing on dead tree stumps.

Fungal tissue is known as plectenchyma that is formed due to well organized hyphae either forming parallel strand-called parenchyma or give the appearance of parenchyma of higher plants called pseudoparenchyma.

Fungi are saprophytes in nature. They tend to live on dead organisms. They do not possess chlorophyll. Their cell wall is made up of chitin.
