Levels of Ecological Organization (English)

What is a biome?

• A large geographical area with distinct plant and animal groups

• A group of similar ecosystems that have the same climate.

• A type of weather pattern that occurs in a specific region

• A classification of soil types based on their mineral content.

What is an ecosystem?

• A community of living organisms interacting with each other and their environment.

• A collection of all the plants, animals, fungi, protists, monerans (bacteria) in an area and the abiotic factors they interact with.

• A group of similar species living in the same habitat.

• The physical environment where organisms live, including climate and soil.

What is a food web?

• A simple chain of food sources in an ecosystem.

• A complex network of feeding relationships among various organisms in an ecosystem.

• A diagram showing the energy flow in a single species.

• A list of all the plants and animals in a habitat.

What is carrying capacity?

• The total number of species in an ecosystem.

• The maximum number of individuals of a particular species that an environment can support sustainably.

• The minimum number of individuals required for a species to survive.

• The average number of individuals in a population over time.

What is a food chain?

• A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A complex network of food webs that includes multiple species.

• A diagram that shows the energy flow in an ecosystem without specific organisms.

• A list of all the plants and animals in a particular habitat.

What is an organism?

• A group of cells working together.

• One individual member of a species.

• A type of ecosystem.

• A collection of different species.

What is biodiversity?

• The variety of life in a particular habitat or ecosystem.

• The total number of species in the world.

• The study of living organisms and their interactions.

• The process of evolution in different species.

What is ecological succession?

• The process of change in the species structure of an ecological community over time.

• The study of how ecosystems interact with each other.

• The process of species extinction in a habitat.

• The migration of species from one ecosystem to another.

What is primary productivity?

• The rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances.

• The total amount of organic matter produced in a given area over a specific time period.

• The process by which plants and animals convert organic matter back into inorganic substances.

• The measure of the efficiency of energy transfer between trophic levels.

What is an abiotic factor?

• Living organisms that interact with each other

• Non-living things and things that have never been alive or part of a living thing.

• Factors that are influenced by living organisms

• Elements that are part of a food chain
