Question: How does biotic factors affect plant growth?

Water, sunlight, and carbon dioxide are necessary for plants to grow. Plants interact with water, sunlight, and carbon dioxide to nourish themselves through photosynthesis. Climate shifts, and temperature fluctuations are influenced by biotic interactions. These factors impact ecosystems in various ways.

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 factors that affect growth of 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.

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.

Are plants abiotic or biotic factors?

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 is a biotic factor for a plant?

A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

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.

What causes plant growth to increase decrease?

There are four primary factors that affect plant growth: light, water, temperature and nutrients. … Changing any of the four can cause the plant stress which stunts or changes growth, or improves growth.

What factor affects the growth of plants in relation to photosynthesis?

Light: Light is the most important factor which affects the growth of the plants. Plants produce their growth hormones, nutrients, food, Oxygen etc with the help of light using Photosynthesis. Hence, A little shortage of light to the plants can affect the growth of the plants.

How do abiotic factors affect plants and animals?

Abiotic factors are the non-living factors that affect living organisms, and so affect communities. These factors do not work in isolation – they combine to produce unique environments which support distinct types of animals and plants. … Soil pH and mineral content: plants need mineral ions like nitrates to grow.

Why are plants biotic factors?

Biotic factors involve living organisms while abiotic factors refer to non-living things. Living are things that can grow,reproduce, produce and use energy,undergo metabolism etc. and plants are definitely living, so they are always considered biotic factors.
