1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. The gases are the fundamental cause of the greenhouse effect. Increase in the amount of greenhouse gases in the atmosphere enhances the greenhouse effect which is creating global warming and consequently the climate change. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries. .
Animals and plants get rid of carbon dioxide gas through respiration. Carbon may also move from fossil fuels to the atmosphere when fuels are burned. Burning of fuels to power factories, power plants, cars and trucks makes carbon to enter the atmosphere as carbon dioxide.

Enlarged roots and stems are found in plants that need to adapt for food storage in winter months. These types of plants lose their leaves during the winter months and cannot participate in photosynthesis, so the extra food storage helps them to survive.
The category of plants that lose their leaves are called deciduous plants.
