Levels of Ecological Organization

What is ecology?

• Ecology is the study of the structure of living organisms.

• Ecology is the branch of biology that studies the interactions between organisms and their environment.

• Ecology is the study of the chemical processes in living organisms.

• Ecology is the study of the history of life on Earth.

What is the biosphere?

• The biosphere is the thin layer of Earth that supports life, encompassing all ecosystems and living organisms.

• The biosphere is a layer of gases surrounding the Earth.

• The biosphere is the part of Earth where weather occurs.

• The biosphere is a type of plant found in tropical regions.

What is the role of producers in an ecosystem?

• Producers convert sunlight into energy through photosynthesis, forming the base of the food chain.

• Producers are organisms that consume other organisms for energy.

• Producers are responsible for decomposing organic matter in the ecosystem.

• Producers regulate the population of consumers in the ecosystem.

What is a biome?

• A biome is a large geographical area characterized by specific climate conditions and ecosystems, such as deserts, forests, and grasslands.

• A biome is a small area with a uniform climate and a single type of ecosystem.

• A biome is a type of animal that lives in a specific habitat.

• A biome is a scientific term for a weather pattern in a region.

What are biotic factors?

• The non-living components of an ecosystem, such as water and minerals.

• The living components of an ecosystem, such as plants, animals, fungi, and microorganisms.

• The physical environment in which organisms live, including climate and geography.

• The chemical substances that organisms produce and use for growth.

What is the difference between a population and a community?

• A population is a group of individuals of different species living in a specific area, while a community is made up of individuals of the same species interacting in a particular environment.

• A population is a group of individuals of the same species living in a specific area, while a community is made up of different populations of various species interacting in a particular environment.

• A population refers to the total number of organisms in an ecosystem, while a community refers to the physical environment where these organisms live.

• A population is a collection of organisms that can interbreed, while a community is a group of organisms that cannot interbreed.

What is the definition of an ecosystem?

• A group of living organisms that do not interact with their environment.

• An ecosystem is a community of living organisms (biotic factors) interacting with their physical environment (abiotic factors) in a specific area.

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

• A habitat that only includes plants and animals.

What is the significance of keystone species in an ecosystem?

• They are the most abundant species in an ecosystem.

• They have a disproportionately large impact on their ecosystem, helping to maintain its structure and balance.

• They are the first species to colonize a barren environment.

• They are species that are at the top of the food chain.

What is a food chain?

• A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

• A food chain is a diagram that represents the different habitats in an ecosystem.

• A food chain is a list of all the organisms in a specific area.

• A food chain is a type of food that is prepared in a specific way.

What is a food web?

• A simple chain of organisms that eat one another.

• A complex network of interconnected food chains that illustrates how different organisms are related through feeding relationships.

• A diagram that shows the energy flow in a single species.

• A list of all the organisms in a specific habitat.
