Question

1. Describe symbiotic relationship.
2Explain digestion in grass eating animals.
3. What will happen when CO2 gas will pass through lime water? Write its chemical reaction

also. ​

Answer 1

Answer:

Certain fungi live inside the roots of plants the plant provide nutrients to the fungus and in return, the fungus provides water are certain nutrients. such relationship is called symbiotic relationship. Explanation: mutualism, commensalism, and parasitism.

Grass eating animals are known as ruminants. ... The process where cud returns to the mouth in small lumps for ruminants to chew is called rumination. Rumination is aided by bacteria present in the rumen which breaks down cellulose in plants. The digested food is then passed to the reticulum.

Resultant carbon dioxide passed through limewater in the right tube, producing a milky solution due to precipitation of the insoluble suspension of calcium carbonate: Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O. ... The milkiness disappears since calcium bicarbonate is water-soluble.

Answer 2

1. Certain fungi live inside the roots of plants the plant provide nutrients to the fungus and in return, the fungus provides water are certain nutrients. such relationship is called symbiotic relationship.   Example: mutualism, commensalism, and parasitism.
2. Grass eating animals are known as ruminants. The process where cud returns to the mouth in small lumps for ruminants to chew is called rumination. Rumination is aided by bacteria present in the rumen which breaks down cellulose in plants. The digested food is then passed to the reticulum.
3. Carbon dioxide reacts with limewater to form a white precipitate of calcium carbonate, CaCO3.

Chemical reaction -

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O.
