Quick Answer: How does biotic factors affects plant growth and development?

Biotic factors refer to the living organisms that affect plant growth and development in various ways. These organisms, both macro-and micro-organisms, are the living components of the environment that influence the manifestation of the genetic factor on phenotypic expression.

What are the factor affecting growth and development in plants?

There are 4 main factors that can affect the growth of your plants. They are water, light, nutrients, and temperature. These four things affect the growth hormones of the plant, which will either make the plant grow quickly or slowly.

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.

What are the effects of biotic factors?

Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition… The development of organims is under the control of abiotic factors. Some are adapted to heat, cold 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.

What are the 5 factors affecting plant growth?

Environmental factors like temperature, light, water, nutrients, and soil affect plant growth from their germination to blooming.

What factors affects the growth of plants in relation to 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 biotic factors affect plants?

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 biotic and abiotic factors that affect the growth of the plant?

Biotic (i.e., weeds, insects, fungi, bacteria, etc.) and abiotic factors (i.e., sunlight, temperature, rain, humidity, drought, salinity, air, soil, pollution, magnetic fields, etc.) can affect plant growth and crop yield in many different ways.

What causes plant growth?

During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. … When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that’s how plants grow.

How biotic factors affect distribution of plants and animals?

Biotic. Biotic factors such as predation, disease, and inter- and intra-specific competition for resources such as food, water, and mates can also affect how a species is distributed.

How do biotic factors affect crop 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.

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.

How does biotic component affect the nutrients of a ecosystem?

Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area. Geologically, organisms create topsoil by breaking down rock layers and dying, which provides detritus with which to form new soil and return nutrients to the ground.

How do biotic and abiotic factors affect each other?

Biotic factors are all of the living organisms within an ecosystem. … Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem.

How do biotic factors affect the distribution of organisms?

Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing – too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.
