9.1.1 Interdependence

• Competition occurs when species compete for limited resources
• Decomposers like fungi and bacteria release nutrients from dead organic matter that plants can then absorb.


  True
• What is the defining characteristic of interdependence within an ecosystem?

  Mutual reliance
• Predation shapes the populations of both predator and prey
• What are two key qualities created by interdependence within an ecosystem?

  Stability and resilience
• Interdependence fosters mutually beneficial relationships between species


  True
• Interdependence creates stability and resilience within an ecosystem
• What do plants provide to nitrogen-fixing bacteria in exchange for usable nitrogen?

  Carbohydrates
• Animals like birds and mammals disperse seeds after consuming them, demonstrating interdependence
• Bees rely on flowers for nectar and pollen, while flowers rely on bees for pollination
• Order the steps in the nitrogen fixation process:

  1️⃣ Bacteria convert atmospheric nitrogen

  2️⃣ Plants absorb the fixed nitrogen

  3️⃣ Plants provide carbohydrates to bacteria
• What do animals gain from seed dispersal by plants?

  Food source
• Interdependence ensures that ecosystems remain balanced and sustainable.


  True
• What role does predation play in an ecosystem?

  Shapes predator and prey populations
• Interdependence fosters mutually beneficial relationships in ecosystems.


  True
• What effect does an altered food web have on an ecosystem?

  Impacts populations and relationships
• What two qualities does interdependence promote within an ecosystem?

  Stability and resilience
• Interdependence creates stability and resilience within an ecosystem
• Pollination between bees and flowers is an example of interdependence
• Lions and hyenas competing for the same prey is an example of competition
• Why is pollination a key example of interdependence?

  Bees pollinate flowers
• What role do decomposers play in interdependence within an ecosystem?

  Release essential nutrients
• What two qualities does interdependence create within an ecosystem?

  Stability and resilience
• Match the type of interaction with its definition:

  Interdependence ↔️ Mutual reliance between species

  Competition ↔️ Two species competing for resources

  Predation ↔️ One species consumes another
• Competition occurs when two or more species compete for limited resources
• What do animals like birds and mammals gain from seed dispersal?

  Food source
• Decomposers release nutrients from dead organic matter, creating an interdependent relationship with plants
• Pollinators like bees rely on flowers for food, while flowers rely on bees for pollination
• Decomposers release nutrients from dead organic matter, creating an interdependent relationship with plants
• Interdependence within an ecosystem promotes stability and resilience.


  True
• Order the steps in the nitrogen fixation process:

  1️⃣ Certain bacteria in the soil convert atmospheric nitrogen

  2️⃣ Plants absorb the fixed nitrogen

  3️⃣ Plants provide carbohydrates to bacteria
• Habitat disruption, such as deforestation, modifies the physical environment
• Changes in one part of an ecosystem can destabilize its natural balance.


  True
• Interdependence is a crucial factor in ensuring the long-term stability of ecosystems.
