Levels of the Ecosystem

What is a decomposer?

• Organisms that produce their own food through photosynthesis.

• Organisms that break down dead organic material, returning nutrients to the soil.

• Organisms that consume living plants and animals for energy.

• Organisms that store energy in the form of fat.

What is an ecosystem?

• A community of living organisms interacting with their physical environment.

• A type of biome characterized by its climate and vegetation.

• A group of species that live in isolation from each other.

• A collection of non-living things in a specific area.

What is an organism?

• A non-living thing that cannot function independently.

• A living thing that can function independently, such as animals, plants, and microorganisms.

• A type of plant that grows in water.

What is the importance of ecosystems?

• Ecosystems provide essential services such as clean air, water, and food, and support biodiversity.

• Ecosystems are primarily important for recreational activities and tourism.

• Ecosystems have no significant impact on human life or the environment.

• Ecosystems are only important for the survival of certain animal species.

Give an example of an organism.

• A hippo is an example of an organism.

What is a population in an ecosystem?

• A group of individuals of different species living together in a specific area.

• A group of individuals of the same species living in a specific area.

• The total number of organisms in a given ecosystem.

• A collection of abiotic factors in an environment.

What is biodiversity?

• Biodiversity refers to the variety of life in a particular habitat or ecosystem.

• Biodiversity is the number of species that can be found in a single organism.

• Biodiversity indicates the health of a single species in an ecosystem.

• Biodiversity is the total number of organisms in a specific area.

What is a community in an ecosystem?

• A community is a group of individuals of the same species living in a specific area.

• A community is made up of different populations of various species living together in a specific area.

• A community refers to the physical environment where organisms live.

• A community is a collection of abiotic factors in an ecosystem.

How do organisms interact in a community?

• Through predation, competition, and symbiosis.

• Only through competition for resources.

• By living in isolation from one another.

• Through random interactions without any specific relationships.

Give an example of a population.

• A population of zebras living in a savanna.

• A single zebra in a zoo.
