Unit 5 - Interaction of Environmental Components

Unit 5 - Interaction of Environmental Components

Important Definitions and Terminologies:

  • Environment: Our environment is the surroundings or conditions in which organisms live or interact.
  • Producer: Plants have the ability to make their own food, which is why they are called producers.
  • Consumers: Organisms that cannot make their own food and depend directly or indirectly on plants for their food are called consumers.
  • Decomposers: Organisms that feed on the dead and decaying matter are called decomposed. Bacteria and fungi are decomposers.
  • Mutualism: A relationship between two organisms in which both are benefitted and none is harmed.
  • All Biotic and Abiotic components interact with each other in an environment. Biotic factors include all animals, plants, and micro-organisms. Abiotic Factors include light, water, air, soil, and temperature.

Exercise (Solved)

  1. Answer the following questions briefly.
    1. Differentiate between biotic and abiotic components.
      Ans: Biotic Factors include all animals, plants, and micro-organisms. Abiotic/Physical Factors include light, water, air, soil, and temperature.

    2. Define parasitism with examples.
      Ans: Type of feeding association between two organisms in which one organism is benefitted and the other is being harmed is called parasitism.

    3. What would happen if there was no light?
      Ans: If there is no sunlight, then plants failed to produce food through photosynthesis, Animals failed to perform any activity. There would be no life without light.

    4. What is the difference between predation and parasitism?
      Ans:Predation: An interaction between two organisms in which one individual feeds on the other is called predation. The animal that hunts down another animal is called the predator.

      Parasitism: Type of feeding association between two organisms in which one organism is benefitted and the other is being harmed is called parasitism.

    5. Differentiate between the physical factors of deserts and rainforests.
      Ans:
      Physical Factors Deserts Rainforests
      Temperature Too high during the day, cold at night High all the time.
      Climate Low rainfall High rainfall
      Water Present in a very limited amount Present in a large amount
      Soil sandy Acidic & Poor Quality
      Air Dry & Warm Humid & Warm

  2. Answer the Questions in detail.
    1. What are biotic factors? Explain in detail.
      Ans: All Biotic and Abiotic components interact with each other in an environment. Biotic factors include all animals, plants, and micro-organisms. Abiotic Factors include light, water, air, soil, and temperature. Let's study how living things interact with each other.

      Producer: Plants have the ability to make their own food, They use abiotic components of the environment to prepare their food.

      Consumers: Animals cannot make their own food and depend on plants for their foods. Animals are categorized as herbivores, carnivores, and omnivores on the basis of feeding behavior.

      Primary consumers of plants are called herbivores, secondary consumers feed on herbivores are called carnivores. An omnivore is a group of animals that feed on both plants and animals.

    2. Explain different relationships among organisms.
      Ans: All living organisms depend on each other for their survival. They interact with each other to fulfill their basic needs such as food, shelter, and protection from danger. Food is the basic need to survive, other than food living organisms need a shelter where they can live freely safe from danger. 

      The tree provides shelter to birds, animals, and human beings.
