Answer:
Plants absorb carbon dioxide, water and sunlight to make their own food, grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean.
Explanation:
Hope this helps.
Answer:
Changes occurs in the environmental conditions directly affect carrying capacity of the ecosystem.
Explanation:
Carrying capacity of the ecosystem refers to the capacity of the environment which adjust plants and animals in a specific atmospheric condition. Suppose in harsh winter, the temperature of the ecosystem is very low which is unbearable for most of the plant and animal species, so very low number of plants and animals are able to live in that environment. In the ecosystem where the winter is harsh and the spring is cold, the population of living organism are more decreasing. If the ecosystem has Harsh winter, Cold spring, and Hot summer, this type of environment hold very low number of living species due to high variation in the environment.

For a particular element if only the group number of 14 is known then the element has 4 valence electrons.
<h3>What is valence electron? </h3>
Valence electron is defined as the number of electrons which an atom must lose or gain to attain the nearest noble gas or stable electronic configuration. “Electrons in the outermost shells that are not filled are called valence electrons”.
The valence electrons are termed as the part of the chemical reactions as they contain more energy as compared to the electrons present in inner orbits. Meanwhile, the number of valence electrons which present also helps us to determine a specific element’s chemical properties, such as its valence or valency, the formation of bonds with other elements.
<h3>Determination of valence electron</h3>
One of the most simple way to find valence electrons is
valance electron = group number (13-17) -10
For group number 14
valence electron = 14-10
= 4
Thus we find that the number of valance electron is 4.
