7.2.1 Levels of Organization

• An individual living thing is referred to as an organism
• Match the level of organization with its description:

  Organism ↔️ Individual living thing

  Population ↔️ Group of the same species

  Community ↔️ Populations of different species
• The global ecosystem, including all living organisms and their physical environment, is called the biosphere
• What is an example of an individual organism?

  Insect
• Arrange the levels of organization in an ecosystem from smallest to largest:

  1️⃣ Individual

  2️⃣ Population

  3️⃣ Community

  4️⃣ Ecosystem
• What is an example of a population in a forest?

  Herd of deer
• What is the description of an organism in an ecosystem?

  An individual living thing
• A community includes populations of different species interacting in the same area.


  True
• An ecosystem includes the community and its physical environment
• The levels of organization in an ecosystem help us understand how living organisms interact with their environment.


  True
• A population is a group of individuals of the same species
• An individual organism is defined by its physical structure, behavior, and ability to carry out life processes.


  True
• A community is a collection of populations of different species
• What are the two main types of components in an ecosystem?

  Biotic and abiotic
• Order the levels of organization in an ecosystem from smallest to largest:

  1️⃣ Individual

  2️⃣ Population

  3️⃣ Community

  4️⃣ Ecosystem

  5️⃣ Biosphere
• What is an ecosystem composed of?

  Biotic and abiotic components
• A population consists of individuals of the same species living in the same area.


  True
• What does an ecosystem include in addition to the community of living organisms?

  Abiotic environment
• A community includes all populations of different species interacting in the same area.


  True
• A group of individuals of the same species living in the same area is called a population
• An individual organism can respire, reproduce, and grow.


  True
• A flock of birds is an example of a population
• A population is a group of the same species living in the same area
• Match the level of organization with its description:

  Organism ↔️ An individual living thing

  Population ↔️ A group of the same species

  Community ↔️ All populations interacting

  Ecosystem ↔️ The community and environment

  Biosphere ↔️ The global ecosystem
• What is the biosphere in terms of ecological organization?

  The global ecosystem
• What is an individual in ecological terms?

  A single organism of a species
• What does an ecosystem include in terms of biotic and abiotic factors?

  Biotic community and abiotic environment
• What is an example of a population in a forest?

  Herd of deer
• Match the community type with its description:

  Forest Community ↔️ Includes trees, animals, and insects

  Lake Community ↔️ Consists of fish, algae, and aquatic organisms

  Desert Community ↔️ Comprises desert plants and animals
• The biosphere includes all living organisms and their physical environment
• Why is it crucial to understand the interconnected levels of organization in an ecosystem?

  To study its dynamics and functioning
