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. 1998.
What abiotic factors do seeds need in order to grow?
Temperature, moisture, air, and light conditions must be correct for seeds to germinate. All seeds have optimal temperature ranges for germination (Table 1). The minimum temperature is the lowest temperature at which seeds can germinate effectively. The maximum is the highest temperature at which seeds can germinate.
How do biotic and abiotic factors help in dispersal of seeds?
Seed dispersal can be accomplished through both abiotic and biotic mechanisms. Abiotic dispersal involves wind and water; biotic dispersal involves autogenic mechanisms, such as explosive fruits, and various animal agents, including insects, fish, reptiles, birds, and mammals.
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.|
Is seed a biotic or abiotic factor?
A seed is the embryo of a new plant and as such is a living thing ,but in a dormant state, which requires being buried in soil or other suitable matter to trigger off the renewal process.
What are the factors needed for the seed to grow?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
What are the 5 factors that affect seed germination?
Several variables might affect the germination, these variables include light, temperature, water, soil type, and air quality.
Which of the following factors help in spreading seeds?
Dispersal of a mustard seed involves animal activities or human activities. The other factors which are involved in seed transportation are water, wind, gravity, etc. > Both explosion mechanisms and animal activities (birds) are involved in the spreading of soybean seeds to the long distance.
What are 5 ways seeds are dispersed?
Below are five ways plants have adapted to disperse their seeds.
- Wind. Wind is one of the most common ways plants disperse their seeds. …
- Water. Plants located near bodies of water use the water to disperse their seeds. …
- Animals. Animals who eat seeds are an excellent source of dispersal. …
- Explosion. …
What are the 5 types of seed dispersal?
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.
What are the 7 biotic factors?
Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals. Examples Water, light, wind, soil, humidity, minerals, gases. All living things — autotrophs and heterotrophs — plants, animals, fungi, bacteria.
What are the 5 abiotic factors?
The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.
What are the 6 biotic factors?
Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Are seeds biotic?
Seeds are living things as they contain an embryo that is capable of germinating to produce a new plant under optimum temperature, humidity and availability of water. … Being a living thing, seeds require energy for metabolic activity which they obtain through the process of cellular respiration.
Is grass biotic or abiotic?
Grass is a biotic component of the environment. Biotic factors are the living components of an ecosystem.
Is seed alive or dead?
A seed is living. Although seeds are dormant (resting) their cells are still alive and performing typical cellular functions. Answer 3: … They are just typically in a dormant state, which means they require very little of the resources necessary to stay alive, until they are in the appropriate conditions to grow.
