Which of the following organisms are in symbiosis in a mycorrhiza?
Assertion [A]: Lichens represent an intimate mutualistic relationship between fungi and photosynthesising algae.
Reason [R]: Mutualistic organisms mostly occupy the same niche and are studied together as they are functionally interlinked.
- Both A and R are false
- Both A and R are true and R explains A
- A is true and R is false
- Both A and R are true R does not explain A

(ii) African catfish in our rivers for aquaculture
(iii) Fish species with its parasites.
(iv) Nile perch and cichlid fish
Which out of these options correctly gives the examples of “Co – extinctions” as a cause of biodiversity loss.

- Species A + Species B +
- Species A - Species B -
- Species A - Species B +
Choose the wrong option:
predation - one benefits and the other suffers
commensalism - one benefits and the other is unaffected
amensalism - one is harmed, other unaffected
mutualism - both species are harmed
