Answer 1

Answer:

1.Autotrophic nutrition, 2.Carbon Dioxide(CO2), 3.temperature,amount of sunlight, amount of co2 in atmosphere, atmospheric conditions, water availability, 4.Parasite mode of nutrition(Heterotrohic), 5.Alga and fungus lives together mutually and helps each other in many ways for e.g.alga prepares food by using water and minerals provided by fungus using cholorophyll.So, this mode of nutrition is called as symbiotic mode of nutrition.6.6C02(g)+12H20(l) in presence of sunlight and chlorophyll--C6H12O6(aq), 6O2(aq), 6H20(l).7.An insectivorous plants traps insects because as we know that insectivorous plants like pitcher plant, venus flytrap and cobra lily contains chlorophyll pigments which helps them in preparation of food by using energy obtained from sunlight still there is a deficiency o protein or nitrogeneous compounds in their body which is very essential for proper growth and metabolism.So, the insectivorous plants traps insects in order to fulfill their protein requirement.
