Answers
1) Autotrophic are those organisms that can prepare their own food with the help of sunlight or chemical energy i.e., photoautotrophic or chemoautotrophic.
Heterotrophic are those organisms that can not make their own food and hence are dependent on other organisms and plants directly or indirectly. Saprobes, parasites, decomposers all come under this category.
2) ATP stands for Adenosine Tri Phosphate (derivative of a nitrogenous base found in DNA)
ADP is Adenosine Di phosphate. This is all like ATP but with only 2 phosphates.
3) Double circulation is where the organisms have their blood passing through their heart twice. For example: Human beings. Once pulmonary and the other systemic.
4) Aerobic respiration requires oxygen. Whereas Anaerobic doesn't. Anaerobic respiration is of two types. Lactic acid and alcoholic fermentation. The former occurs in yeast, human muscles and bacteria whereas takes place only in bacteria.
5) Glomerulus is the dense capillary network present in bowman's capsule of a nephron. Whereas Nephrons are the functional and structural units of kidney. These are the sites where actual filteration, absorption and secretion takes place. There are millions of nephrons in one kidney.
