Question

A balance between plants and animals is essential.why

Answer 1

Animals and plants both have been positive to each other, the latter have been helpful in some or the other ways. The balance of the plants and animals have brought a change to the earth. If the plants were not present then the excess of CO2 and some other toxic products will be still roaming freely and could also cause a major harm to the geothermal animals especially humans.
The humans have returned the favour by planting as much theheohheress as possible and give the planet a rejenuvative look. The humans have also lend the support for plants by holding various campaigns and slogan from the defence of themselves and attack at their own species.
So, the perfect balance has always been found in both of them.
Plants by photosynthesis and animals by respiration, by which the two get benefited in one or the other way.

Answer 2

Answer:

• All animals use the oxygen that is produced by plants to breathe.
• In exchange, mammals release carbon dioxide, which plants absorb to create food.
• As a result, the balance between carbon dioxide and oxygen is maintained by this give-and-take connection.
• Because plants are autotrophs, able to produce their own food, and animals are heterotrophs, unable to do so, they must rely on plants (autotrophs) for their sustenance, maintaining a balance between the two is crucial.
• In addition, plants require CO2, which is released into the environment by animals during respiration.
• This, in turn, causes plants to release oxygen, which is necessary for mammals to survive.
