Biotic vs. Abiotic
Cards (15)
- Biotic Factors
- The term biotic is made up of two terms: “bio” means living organism and “ic” means like, thus combined they are known as living organisms.
- Therefore it can also be defined as all living organisms present on earth are known as biotic components.
- Example of Biotic Factors
- Plants
- Animals
- Human Beings
- Decomposers
- Yeast
- Insects
- Abiotic Factor
- Nonliving parts of an ecosystem are termed abiotic factors.
- They play a crucial role in shaping ecosystems as both biotic and abiotic factors interaction is a must for the stability of the ecosystem.
- Examples of Abiotic Factor
- Air
- Weather
- Water
- Temperature
- Humidity
- Altitude
- pH
- Level of Soil
- Water Flow Rate
- Water Depth
- Biotic resources - encompass the living organisms in the ecosystem
- Abiotic resources - the non-living, which are physical conditions and chemical factors which influence the ecosystem
- Biotic resources depend on abiotic resources for survival as well as reproduction
- Abiotic factors are independent of basic factors
- Examples of Biotic Factors:
- Producer
(1) Plants(2) Algae(3) Bacteria - Examples of Biotic Factors:
- Consumers (Primary and Secondary)
(P) Cow and Goat(S) Lion and Tiger - Abiotic Factors:
- Climate
- pH Balance
- Light
- Water Currents
- Abiotic Stress - imposed on plants by environment may be either physical or chemical, while as biotic stress exposed to the crop plants is a biological unit like diseases, insects, etc.
- Biotic stress - in plants is caused by living organisms, specially viruses, bacteria, fungi, nematodes, insects, arachnids and weeds. The agents causing biotic stress directly deprive their host of its nutrients can lead to death of plants.
- Examples of Abiotic Stresses
- Crop Plants
- Cold
- Salt
- Drought
- Toxin
- Examples of Biotic Stresses:
- Fungi
- Virus
- Bacteria
- Nematodes
- Insects
- Types of diseases, infections and damage to crop plants
