Answer:
Constrictive
Explanation:
Constrictive Population Pyramids are typically used to describe a population mainly consisting of the elderly and is shrinking.
They can often look like beehives and typically have an inverted shape.
Under normal conditions it is not toxic
Adding ammonium nitrate to water turns the mixture cold and is a good example of an endothermic chemical reaction
Answer:
Unsaturated
Explanation:
A fatty acid is said to be unsaturated if it has one or more double or triple covalent bonds in its carbon chain
The sun’s energy causes water to evaporate from oceans and lakes into the atmosphere. {{{Plants and animals also release water vapour into the atmosphere as they breathe( or sometimes by evaporation of sweat from the skin).}}} When the atmosphere cools, water vapor condenses; making clouds that might produce rain or snow. Water has been recycled in its different forms as ice, liquid, or vapor for more than 3.5 billion years.
<span>As for the carbon cycle, plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make the substances they need for growth. The process of photosynthesis incorporates the carbon atoms from carbon dioxide into sugars. {{{Animals,such as rabbits, eat the plants and use the carbon to build their own tissues. Other animals, such as foxes, eat the rabbits and then use the carbon for their own needs. These animals return carbon dioxide into the air when they breathe, and when they die, since the carbon is returned to the soil during decomposition. The carbon atoms in soil may then be used in a new plant or small microorganisms.}}} Ultimately, the same carbon atom can move through many organisms and even end in the same place where it began. Herein lies the fascination of the carbon cycle; the same atoms can be recycled for millennia! </span>
