The system of agriculture that uses organic fertilizers including compost manure, etc. It can have some struggles like pests, difficulty in marketing, limited organic food. Smart strategy, responsible public activity, scientific planning, and government support can help it to overcome.
<h3>What is the importance of organic farming?</h3>
Organic farming is very much important as it can yield higher as compared to conventional farming.
The main reason behind the struggling of the farmers related to organic farming are:
- Lack of marketing strategies.
- Pest attacking the crop.
- It require more time as compared to the conventional one.
- limited supply of organic food.
The farmers should be guided to have smart strategy, contacting with government to overcome the problems, scientific planning, etc.
Thus, by adopting the listed strategies one can overcome the struggle in organic farming.

Arthropods are fed on (or preyed on) by the animals and birds according to the food web. Therefore, a decrease in arthropod population will cause a subsequent decrease in that of animals too. This is because the animal population will compete for the fewer arthropods. This increased competition will lead to a survival of the fittest and a subsequent decrease in the animal population.
Explanation:
A food web is used to indicate the cycle of food, through feeding relationships, in an ecosystem hence concomitantly also show the flow of energy in the ecosystem. Food webs are made of several to many interlinked food chains.
Usually the primary producers are at the bottom of the food chain while tertiary consumers are at the top.

Answer:
D. Microglia
Explanation:
Microglia are phagocytic, which means that they are cells that can engulf other cells and particles. Microglia protect the CNS by engulfing foreign particles and bacteria. They act also as a clean-up crew that help remove dead cells. They are found in both the brain and spinal cord, which make up the Central Nervous System, or the CNS.
Answer: B. It is associated with a negative change in free energy.
Explanation:
<u>A polymer is an organic compose made of many simple molecules </u>that are repeating structural units called monomers. Examples of polymers are DNA, lipids, carbohydrates and proteins.
Polymers are broken down into monomers in a process known as hydrolysis, which is a reaction that splits the bond between monomers. During these reactions, the polymer is broken into many components.
This process of breakdown is called catabolic reactions, which, as it was said, is the break down of larger molecules into smaller molecules through the hydrolysis of its bonds. <u>This reaction releases energy which was found in the bond between this monomers.</u> And, when energy is released, there is a negative change in free energy. This means there is more free energy available for the cell to be used.
