Answer:

Carbon is found in all living organisms. The constant flow of carbon on Earth through organisms and the air is known as the carbon cycle.

Plants absorb carbon from the atmosphere in the form of carbon dioxide.

They use it for respiration and photosynthesis.

Animals consume plants, transferring carbon along the food chain. Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.

Carbon enters back into the atmosphere in the form of carbon dioxide gas.

Explanation:

All life on Earth is made up of a carbon-based structure. An atom of carbon has 6 electrons (4 valence electrons) that easily bond to other other compounds. Covalent bonds involve exchanging electrons; these usually are formed with oxygen, nitrogen, phosphorus and most frequently hydrogen.

How do guard cells maintain homeostasis?

Mice21 [21]

Answer:

Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.
