strength: it provides raw material for plants and major component of food.
weaknesses: it increases earth's temperature and change the habitat.
Explanation:
The diagram shows the carbon cycle which is important cycle present on the earth. This carbon is present in carbondioxide form which is used as a raw material by plants in order to make their own food. This carbon is also present in different organic compounds. When its concentration increases in the atmosphere, the temperature of the atmosphere increases and many areas are not suitable to live for many plants and animals.
All vascular plants have water-conducting tissue and are better adapted for life on land than the bryophytes; they are also characterized by a dominant sporophyte generation.
In the periodic tables metals are on the left side and nonmetals are in the right side.... so we can know whether an element is metal or nonmetal by it's position on the periodic table..
