Fungi are decomposers, they obtain their food from dead organic matters. Fungi obtain their nutrient this way because they can not produce their own food. To produce their own food they need chloroplast in their cells to obtain energy from the sun. And they also need the ability to fix nitrogen which they will incorporate into the food they produce. Because they lack the ability to do this thing, they have to adapt to eating dead materials. <span />
In gilled mushrooms, gills are used to maximize spore production. Gills of some mushrooms are folded and crowded to obtain maximum spore production. Other gills, spread towards the outer cap which gives way to new gill growth in between gills which is called partial gill. Some of the mushrooms grow gills in layers too.
Answer:
Carbondioxide gas is a greenhouse gas which is released in the atmosphere by industries and respiration process. This carbondioxide gas is absorbed by the plant from the atmosphere in the process of photosynthesis. Some carbondioxide is also dissolved in the sea water. When the concentration of carbondioxide is increased in the atmosphere, increase in the temperature occurs due absorption of infrared radiation coming from the earth after reflection. This increase in temperature is called global warming.
