The meteorite was probably 1<span>0 to 15 km (6.2 to 9.3 mi) wide</span> and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.
Well, since I am in 8th grade I can help, try gthis...
<span>The process by which a plant absorbs energy from the sun is, as you know, photosynthesis.
Remember the Law of Conservation of Energy - when energy is transferred,
it is neither created nor destroyed but rather takes a new form.
In this case, the plant takes energy in from the sun (through sunlight,
which transfers through radiation) and "leaves" the plant after the
process has occurred in a form of potential energy - the oxygen produced
in this process has potential energy.</span>
Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
Answer:
Biogas is composed mostly of methane (CH4), the same compound in natural gas, and carbon dioxide (CO2).
Explanation:
The food chains make up the food webs
