Detailed explanation-1: -Explanation: In photosynthesis, plants take in carbon dioxide to make glucose and oxygen. If plants are decreased, there won’t be enough plants to take in CO2, therefore CO2 will increase.

Detailed explanation-2: -Plant productivity supports wildlife and serves as the basis of a multitude of food chains. The decline of plants means there will be less food, which can further lead to declines in animal populations.

Detailed explanation-3: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.

Detailed explanation-4: -1 Answer. The rate of photosynthesis will decrease as the amount of CO2 decreases.

Detailed explanation-5: -High CO2 levels cause plants to thicken their leaves, which could worsen climate change effects, researchers say. Plant scientists have observed that when levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves.
