Answer:
A biological community in which association takes place between the organisms and their physical surroundings is termed as an ecosystem. It can also be defined as an association between the nonliving and living components found within the environment. A particular geographical region, which is specified for the species thriving within it is known as a biome.  
A branch of science, which deals with the natural procedures that comprise fire within an ecosystem and the ecological influences it imparts, the association between the biotic and the abiotic constituents of an ecosystem with the fire, and the role played by fire within an ecosystem is termed as a fire ecology.  
Different kinds of ecosystems like savanna, prairie, coniferous forests and chaparral have originated by the contribution of the fire, which plays an essential role in the renewal and vitality of the habitat. Different kind of plant species needs the assistance of fire to establish, to reproduce, or to germinate. In case, if the suppression of wildfire takes place, it will eventually result in the eradication of various plant species and the animals that rely upon them.

Answer:
B. Elks attatch leaves and grasses to their antlers to help them appear larger.
Explanation:
Reason 1: If the Elk appears larger other male Elks would be too scared to fight that Elk for a female. Reason 2: The female Elk will be more attracted to the larger male Elk even if it's largeness is fake.
 
        
             
        
        
        
Answer:
The correct answer is non-disjunction at the time of meiosis. 
Explanation:
A disorder, which takes place in males exhibiting an additional X-chromosome and is an outcome of an error in cell differentiation resulting in anomaly known as the Klinefelter's syndrome. Due to non-disjunction the egg or the sperm may acquire an additional X-chromosome. When these unusual cells take part in the genetic makeup of a person, then that individual most probably suffers from the condition termed as Klinefelter's syndrome.  
In the majority of the circumstances, the division of the cells takes place generally during the development of the sperm, and at the same time, there may be certain errors at the time of egg development. Generally, the condition is mostly seen in the offspring of women that conceive after the age of 35.  
 
        
             
        
        
        
As their contents are used for energy during weight loss, fat cells get smaller in size, but their overall number doesn't change.
<h3>Where Does Fat Go When Weight Is Lost?</h3>
- Fats are liberated from fat cells and transferred to the mitochondria, the energy-producing organelles in your body's cells, by sustaining a steady calorie deficit. Here, a number of procedures break down the fat to create energy.
- These same cells may become smaller when you lose fat, yet they continue to exist in roughly the same numbers. Therefore, fewer fat cells, not more, are the main cause of changes in body form.
- Also implied by this is that even when you lose weight, fat cells are still present and can readily regain their original size if efforts are not made to keep the weight off.
