The process is decomposition.
Decomposition is a process by which organic substances, like leaves, are broken down into simpler matter. A lot of different types of organisms, called the decomposers, will consume the organic substances(like dead plants, dead animals) and continue an essential part of the nutrient cycle. This is important for recycling the organic matter that occupies space in the biosphere.
The answer is hydrogen bonds
Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
