Question 7
Two organisms are good friends and live together. One provides shelter, water, and nutrients while the other prepares and provides food. Such an association of organisms is termed as

(a) saprophyte
(b) parasite
(c) autotroph
(d) symbiosis

Answer 1

The answer is option (d).

Some organisms live together and share shelter and nutrients. This is called symbiotic relationship or symbiosis. For example, in organisms called lichens, a chlorophyll-containing partner, which is an alga and a fungus live together. The fungus provides shelter, water and minerals to the alga and in return, the alga provides food which it prepares by photosynthesis.
