1 lichen
2 algae
3 rhizobium
4 pitcher plant
Answers
answer of this question is "lichen"
Answer:
Rhizobium
Step-by-step explanation:
Parasitic plants are those plants who cannot make their own food and rely on other plants (or their host) for food/nutrients. From all the other options in the question, (1) and (2) consists of chlorophyll and are able to make their own food through photosynthesis.
The option (4) is an insectivorous plant and its main source of nutrients are insects. They may not be able to make their own food but can get food on their own.
The option (3) is the one because it cannot make its own food since it lacks chlorophyll and other things. They can convert atmospheric nitrogen to usable nitrogen for the plants and have a symbiotic relationship with legumes.
So, Rhizobium is your answer.
Hope this helps...
