How do biotic factors affects the growth of the crop?

What biotic factors help plants grow?

Water, sunlight and carbon dioxide are necessary for plants to grow. The biotic interaction is that plants use water, sunlight and carbon dioxide to create their own nourishment through a process called photosynthesis. On a larger scale, abiotic interactions refer to patterns such as climate and seasonality.

What are the effects of biotic factors?

The biotic factors include the influence of living organisms, both plants and animals upon the vegetation. Any activity of the living organism which may cause marked effects upon vegetation in any way is referred to as biotic effect. The biotic effect may be both direct and indirect.

How does abiotic factors affect plant growth?

Temperature and moisture are important influences on plant production (primary productivity) and the amount of organic matter available as food (net primary productivity). Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.

How do biotic factors affect plants?

Herbivores with significant deleterious effects on crop growth and yield are called pest. Damage caused by these biotic factors are varied such as death of the entire plant or organs, reduced root, stem, leaf or inflorescence mass, total defoliation, bores and holes on plant parts, and other marks of feeding.

How do biotic and abiotic factors affect crop production answer?

Answer: Biotic factors such as pests, insects and diseases reduce the crop production. … Weeds also reduce crop productivity by competing with the main crop for nutrients and light. Similarly, abiotic factors such as temperature, wind, rain etc.

How does biotic factors affect the environment?

The biotic factors in an ecosystem are the living organisms, such as animals. … These living organisms affect each other and influence the health of the ecosystem. A healthy ecosystem has a balance of biotic examples; a large increase or decrease in population of one species can impact many others.

How does biotic and abiotic factors affect population growth?

The carrying capacity depends on biotic and abiotic factors. If these factors improve, the carrying capacity increases. … If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.

What are the biotic factors in crop production?

Biotic constraints to agricultural production are broadly identified as weeds (plants), pests (animals), and diseases (fungi and bacteria), and their related biological interactions (namely, competition, herbivory, and predation and parasitism), which cause reductions in physical yields or yield quality.

What biotic factors affect photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

  • Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide. …
  • Carbon dioxide concentration. …
  • Temperature.

How do fertilizers affect plant growth?

Fertilizers provide essential nutrients to plants in form of soluble salt compounds, and directly affect plant growth. … Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant.
