Question

Animals and plants both use -----------for respiration. But there is a balance of levels of gases. It is because
plants are refilling through the process of -----------. The plants consume ------------and water in the
presence of chlorophyll and sunlight to convert it into food and -------- which is consumed by the animals
for their respiration.

Answer 1

oxygen, photosynthesis, carbon dioxide,

Answer 2

Answer:

Animals and plants both use oxygen for respiration. But there is a balance of levels of gases. It is because  plants are refilling through the process of photosynthesis. The plants consume carbon dioxide and water in the  presence of chlorophyll and sunlight to convert it into food and oxygen which is consumed by the animals  for their respiration.

Knowledge Bytes:

→ Photosynthesis:

Photosynthesis is the process by which autotrophic organisms produce the food they require. In this process, plants take in carbon dioxide and water vapour in the air through tiny pores in the leaves called stomata and covert them to glucose and oxygen in the presence of sunlight and chlorophyll.

Word equation:

$\sf{\implies\:Carbon\:dioxide+Water\xrightarrow{\text{Sunlight+Chlorophyll}}Glucose+Oxygen}$

Chemical equation:

$\sf{\implies\:6CO_2+6H_2O\longrightarrow\:C_6H_{12}O_6+6O_2}$

→ Photosynthesis and respiration - A cycle:

Photosynthesis in plants and respiration in animals are two processes that benefits each other. The oxygen released by plants is used by animals and the carbon dioxide given out by animals is used by plants. It i a continuous process that benefits both plants and animals.

This is also the reason why deforestation has a great impact in the environment. With less plants, this conversion process gets imbalanced and thus causes various difficulties ranging from impure air to increased amount of carbon dioxide.
