Answer:
Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
Explanation:
Answer:
If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.
For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.
The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.
Hope it help!
The answer is photosynthesis. Hope that helps :)
Hi there! The level of carbon dioxide affects the global temperature, because it causes heat to be trapped into the atmosphere and heat the Earth up. CO2 (formula for carbon dioxide) is a naturally made gas formed by breathing, but lots of it is bad for the planet. Human activities like driving cars and running factories add much more toxic gasses into the environment. Global warming is the cause of melting ice caps, which leads to rising sea levels, and is also the cause of some plant and animal species dying out.
