Match the items given in Column I with those in Column II:
| Column I | Column II |
| Chlorophyll | Rhizobium |
| Nitrogen | Heterotrophs |
| Cuscuta | Pitcher plant |
| Animals | Leaf |
| Insects | Parasite |
Correct Answer:
| Column I | Column II |
| Chlorophyll | Leaf |
| Nitrogen | Rhizobium |
| Cuscuta | Parasite |
| Animals | Heterotrophs |
| Insects | Pitcher plant |
Pitcher plants are carnivorous or insectivorous plants. Their leaves are modified as traps. They follow a pitfall trapping mechanism to capture prey. These plants are colorful and attract a wide variety of insects.
The insectivorous plants grow in soil that does not contain sufficient nitrogen minerals. These plants (e.g. pitcher plants) are green and carry out photosynthesis to obtain a part of their food. But they do not get enough nitrogen from the soil in which they grow.
Hence, insectivorous plants feed on insects to obtain the nitrogen needed for their growth.
Cuscuta is a parasitic plant. It lacks chlorophyll to conduct photosynthesis and thus is not in green color. It contains different pigment which absorbs a specific wavelength of light but is not able to absorb the yellow light hence it is reflected back and appear yellow.
