PROTEINS ARE MADE OF NITROGENOUS SUBSTANCES . FROM WHERE DO PLANTS OBTAIN NITROGEN ? Q5. WHAT ARE INSECTIVOROUS PLANTS ? GIVE EXAMPLES. Q6. WHAT IS SAPROTROPHIC NUTRITION? GIVE EXAMPLES OF SOME SAPROTROPHS.
Answers
Answer:
Baird. The act of breaking apart the two atoms in a nitrogen molecule is called "nitrogen fixation". Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea.
Ans 5 -
Insectivorous plants include the Venus flytrap, several types of pitcher plants, butterworts, sundews, bladderworts, the waterwheel plant, brocchinia and many members of the Bromeliaceae.
Ans 6-
The mode of nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Example - Rhizopus (bread mould), Mucor (pin mould), Yeast, Agaricus (mushroom)

Thank you
There are a lot of answers. Please read it to understand it.
1. In the absence of green plants, there would not be the process of photosynthesis. Without photosynthesis it will affect the plant as it could not make food. The survival of almost all living organism directly or indirectly depends upon the food made by the plants. Besides oxygen which is essential for the survival of all living organisms is produced during photosynthesis. Thus, we can say that life would be impossible on the earth in the absence of photosynthesis.
2. Plant leaves obtain different colours due to the presence of different types of pigment. But chlorophyll is also present on these leaves but remains hidden or masked among other pigments. These chlorophylls perform photosynthesis just like other green plants. So coloured plant leaves also carry out photosynthesis like green plants.
3. Wheat Dough when left in the open emits fouls smell as Carbohydrates in wheat dough encourage the growth of yeast and other saprophytic fungi which break down carbohydrates and emit a foul smell.
4. Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants can convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby making it suitable for the plants to take it.
5. Insectivorous means insect-eating plants, they derive most of their nutrition from the insects, that they trap and consume. Venus flytrap, pitcher plant and cobra lily are some examples of the insectivorous plants
6. The mode of nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Example: Fungi, Mushroom, Yeast, Etc.
