Explanation:
Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems. 
 
        
             
        
        
        
Answer: 
$5 is the cost of 1 pound of walnuts 
P (Pounds) = 5D (Dollars)
Explanation:
Since 10 pounds of walnuts = $50.
 Let 1 pound of walnuts = Z
then, cross multiply 
So, Z = ($50 X 1 pound) / 10 pounds 
Z = 50/10
Z = $5 
Thus, 1 pound of walnuts will cost 5 Dollars while P (Pounds) = 5D (Dollars) is the equation that shows the relationship between pounds and dollars 
 
        
                    
             
        
        
        
Answer:
They can destroy the ecosystem or out - compete a native species.
Explanation:
For example, if an invasive species of tree is taller than the native species of tree and therefore takes up more sunlight, leaving the shorter native tree not enough sun, then it will effectively kill the native tree.
Also non - native and invasive are not the same thing. A non - native species doesn't necessarily mean it's invasive. It is only invasive if it begins to have a significant impact on the ecosystem it is inhabiting. 
 
        
             
        
        
        
<span>Solar and wind is the list that contains the only examples of renewable sources of energy. Solar energy is generated by using sunlight while wind energy is generated by using wind turbines. Hence both of these energies does not require any form of burning of fuels and hence are renewable sources of energy.</span>
