Your question: What are the biotic and abiotic factors that destroy the grains?

(a) Biotic factors like insects, rodents, fungi, mites and abiotic factors like inappropriate temperature and moisture cause degradation in quality, loss in weight, poor germination, discolouration of produce, all leading to poor marketability.

What are the biotic and abiotic factors that affect storage of grains?

Besides the biotic factors, there are some non-living factors that affect the stored grains. These include air, moisture, and temperature. An unbalanced amount of these factors can harm the grains drastically.

What are 5 biotic and abiotic factors?

Key Differences (Biotic Factors vs Abiotic Factors)

Basis for Comparison Biotic factors Abiotic factors
Examples Humans, insects, wild animals, birds, bacteria, etc. are some examples of biotic factors. Soil, rainfall, humidity, temperature, pH, climate, etc. are some examples of abiotic factors.

How do abiotic factors causes loss to stored grains?

Ans: During the storage of grains both biotic and abiotic factors cause losses to the grain. … and various abiotic factors such as moisture, temperature, lack of sunlight, etc. are responsible for losses of grains. These factors cause loss in weight, degradation in quality and poor germinability.

What are the factors that affect storage of grains?

Four factors which greatly affect grain storability are (1) grain moisture content; (2) grain temperature; (3) initial condition of the grain; and (4) insects and molds. These factors are all interrelated.

What are the factors that can cause loss of storage crops?

The storage losses are affected by several factors, which can be classified into two main categories: biotic factors (insect, pest, rodents, fungi) and abiotic factors (temperature, humidity, rain) [32]. Moisture content and temperature are the most crucial factors affecting the storage life.

How biotic and Abiotic factors can affect agricultural produce during storage?

Biotic factors like insects, rodents, pests, and many more spread the disease and reduce crop production. … Abiotic factors like humidity, temperature, moisture, wind, rain, flood and many more destroy the crop raise. Abiotic factors like hot, cold, drought, salinity, etc. affect crop production.

What are the 5 biotic factors?

Like all ecosystems, aquatic ecosystems have five biotic or living factors: producers, consumers, herbivores, carnivores, omnivores, and decomposers.

What are 5 biotic factors examples?

5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.

What are biotic factors and abiotic factors?

Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.

What factors affect the quality of grains?

Grain quality is defined by several factors such as physical (moisture content, bulk density, kernel size, kernel hardness, vitreousness, kernel density and damaged kernels), sanitary (fungal infection, mycotoxins, insects and mites and their fragments, foreign material, odour and dust) and intrinsic factors (milling …

IMPORTANT:  Which type of pyramid of number is present in tree ecosystem?

How do food grains get spoiled?

Ans. Food grains get spoiled by insects, fungi, rodents, bacteria, moisture, temperature in the place of storage. Storage losses can be minimised by following preventive and control measures. The seeds/grains that are to be stored should be dry, with no moisture in it.

What causes hot spots in grain?

If warm grain is placed into storage and left undisturbed, convection currents develop and cause hot spots and moisture condensation. The greater the temperature differential (the difference between the temperature of the grain and the outside temperature), the stronger the convection currents.
