True
The crop productivity is basically affected by pests mainly weeds, pathogens and animals. According to a research by E.-C. OERKE, the potential loss to wheat and cotton crop was 50 % and 80 % respectively. 25-30 % of soya bean is lost every year due to pest attack. Out of all pests the most dangerous is the animal which as per an estimate has high potential of destroying the crops up to 34% while pathogens can destroy 16-18 % of crops.
Environmental factors do influence natural selection because they can increase or decrease the population of a species, by selecting those with only favorable traits.
Answer:
the condensation of water vapor as it touches a colder surface.
Explanation:
The answer to the above question is Fatty acids.
<h3>What are
Fatty acids?</h3>
A fatty acid is a carboxylic acid with an aliphatic chain that is either saturated or unsaturated. This definition applies to chemistry, particularly biochemistry. The majority of naturally occurring fatty acids have an unbranched chain with 4 to 28 carbon atoms, which is an even number. In some species, like microalgae, fatty acids make up a significant portion of the lipids (up to 70% by weight), but in other organisms, they are present as one of the three main types of esters: triglycerides, phospholipids, or cholesteryl esters rather than in their solo form. Fatty acids are crucial nutritional sources of energy for animals in any of these forms, as well as crucial cellular building blocks.

Answer:
A. It allows plants to use nitrogen to grow.
Explanation:
However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.
Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).
It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.
