4.1.1 Interdependence

• The key biotic factors influence interdependence in ecosystems.organisms
• What is the role of producers in interdependence?

  Produce food through photosynthesis
• Interdependence in ecosystems ensures the survival of living organisms through mutual reliance.


  True
• What role do consumers play in ecosystems?

  Consume other organisms for food
• Symbiotic relationships are crucial for the overall balance and functioning of an ecosystem.
• Consumers in ecosystems can be herbivores, carnivores, or omnivores.
• Producers convert carbon dioxide and water into glucose through photosynthesis.
• What does interdependence in ecosystems refer to?

  Reliance on living organisms and the non-living environment
• Abiotic factors include sunlight, water, and soil.

  True
• What happens during nutrient cycles in ecosystems?

  Nutrients are recycled
• Match the abiotic factor with its description:

  Sunlight ↔️ Provides energy for photosynthesis

  Water ↔️ Essential for life processes

  Temperature ↔️ Affects biological rates
• What are symbiotic relationships in ecosystems?

  Interactions between different species
• What is the process by which producers make their own food?

  Photosynthesis
• Sunlight provides the energy for photosynthesis.

  True
• Biotic factors are living organisms that affect an ecosystem.


  True
• Match the factor type with its description:

  Biotic ↔️ Living organisms

  Abiotic ↔️ Non-living components
• Order the types of consumers based on their diet:

  1️⃣ Herbivores

  2️⃣ Carnivores

  3️⃣ Omnivores

  4️⃣ Scavengers
• Match the abiotic factor with its description:

  Sunlight ↔️ Energy for photosynthesis

  Water ↔️ Essential for life processes

  Soil ↔️ Provides nutrients and support
• Scavengers aid in nutrient recycling by cleaning up dead carcasses
• What do herbivores primarily feed on?

  Plants
• What do omnivores consume?

  Plants and animals
• What is a food chain?

  Linear sequence of organisms
• Match the concept with its description:

  Food Chain ↔️ Linear sequence of organisms

  Food Web ↔️ Complex interconnected feeding relationships
• Match the factor type with its description:

  Biotic ↔️ Living organisms in the ecosystem

  Abiotic ↔️ Non-living components of the ecosystem
• Biotic factors are interdependent for the overall balance and functioning of an ecosystem.
• The interdependence of biotic factors is crucial for ecosystem balance.


  True
• What role do fungi and bacteria play in ecosystems?

  Decomposers
• Sunlight provides the energy for photosynthesis by producers
• What abiotic factor provides energy for photosynthesis?

  Sunlight
• What do producers convert sunlight, water, and carbon dioxide into?

  Glucose
• Decomposers depend on the organic matter provided by the death and decay of other organisms.


  True
• What does a food web illustrate in an ecosystem?

  Interdependence
• Food webs illustrate the interdependence between producers, consumers, and decomposers in an ecosystem.


  True
• Producers convert sunlight into chemical energy through photosynthesis.


  True
• Nutrient cycles involve the continuous flow of essential elements between biotic and abiotic components of an ecosystem.


  True
• Energy transfer in ecosystems follows a linear flow.
• Biotic factors are living organisms that affect an ecosystem.organisms
• Decomposers like fungi and bacteria break down dead organic matter.

  True
• Plants depend on sunlight and animals depend on plants for food.


  True
• Why is water essential for life processes in ecosystems?

  Movement of nutrients
