<u>ANSWER:</u>
When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star. 
<u>EXPLANATION:</u>
- Supergiant are very large stars in the galaxy that end their lives very quickly. 
- When a supergiant star loses its fuel, it blows itself by a supernove explosion. 
- When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star. 
- This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.

Answer:
A) 1000
Most viruses are 1000 times smaller than the average cell
 
        
                    
             
        
        
        
The answer is D because <span>In </span>exocytosis<span>, materials are </span>exported<span> out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones.</span>
        
                    
             
        
        
        
They break down organic matter into nutrients for other organisms.
<h3><u>What is the role of decomposers in ecosystem?</u></h3>
Saprophytes like fungus and bacteria are decomposers. They rely entirely on the dead and decomposing organic debris to survive. Decomposers are crucial to the ecology because they assist in recycling nutrients so that plants may utilise them again.
The function of a decomposer in the ecosystem is as follows:
- By disintegrating dead plants and animals, they first serve as a purifying force for the environment.
- They aid in the nutrient recycling.
- By allowing the dead to decay, they provide room in the biosphere for new life.
- For the benefit of reuse by producers like crop plants, they assist in reintroducing the various elements to water, soil, and air.
