Frequent question: Which abiotic factors are needed for food production in plants?

The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.

What abiotic factor is used by the plants in making their food?

Sunlight is the main source of energy on Earth, which makes it an extremely important abiotic factor. Sunlight is necessary for photosynthesis, the process where plants use carbon dioxide (CO2) and water to make sugar – food for the plants that later becomes food for animals.

What abiotic factors are important for a plant to grow?

The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity. Their actions are interrelated in a functional network involving all major processes of plant physiology in the ecological performance of plants (Fig. 3). Fig.

How does an abiotic factor affect food 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. Resistant variety can withstand these factors and give a high yield.

What are the 4 abiotic factors a plant needs to do photosynthesis?

Water, sunlight, and carbon dioxide are necessary for plants to grow. Plants interact with water, sunlight, and carbon dioxide to nourish themselves through photosynthesis.

How abiotic factors affect plants?

Abiotic factors include: Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. … Temperature: temperature is a limiting factor for photosynthesis – and low temperature therefore limits growth of plants.

What are the 7 abiotic factors?

In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.

Which abiotic factors are more important for plant growth and distribution and which are more important for animal growth and distribution?

Temperature and Water. Temperature and water are important abiotic factors that affect species distribution.

What are agricultural abiotic factors?

In the context of the study in question, biotic components are agricultural plants and livestock whereas abiotic factors are climatic factors such as temperature, rainfall, wind, humidity, sunlight, and air as well as edaphic factors such as geology (rocks), topography, inorganic minerals and soil.

What are some examples of abiotic factors?

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.

What biotic and abiotic factors are required for seed growth?

Biotic factors, intrinsic to the seed and/or interactions with other organisms and abiotic factors, such as light, temperature, humidity and fire, affect germination differently (Baskin & Baskin 1998. … Seeds – ecology, biogeography, and evolution of dormancy and germination.

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.

How biotic factors affect agricultural production?

Biotic factors such as pests, insects and diseases reduce the crop production. A pest causes damage to our crops by feeding. Weeds also reduce crop productivity by competing with the main crop for nutrients and light. Similarly, abiotic factors such as temperature, wind, rain etc.
