Aquarium Ecosystem Components and Interactions

The video tutorial by Lord Kriki covers a lab practical on aquatic ecology, focusing on biotic and abiotic components in a house aquarium. It introduces the objectives of identifying biotic components, determining airborne components, and explaining interactions between biotic and abiotic components. The video details the components in the aquarium, such as fish, natural wood, and artificial coral reef, and explains their roles. It defines biotic and abiotic components and discusses their relationships, such as how water quality affects fish and microorganisms. The conclusion emphasizes the importance of abiotic factors in supporting biotic life.

What is one of the main objectives of the aquatic ecology lab practical?

• To count the number of fish in the aquarium

• To identify types of biotic components

• To measure the temperature of the water

• To determine the pH level of the water

What type of fish is mentioned as being in the aquarium?

• Betta fish

• Goldfish

• Guppy

• Angelfish

What is the purpose of the water pump system in the aquarium?

• To filter the water

• To provide light for the plants

• To heat the water

• To pump out dissolved oxygen

How are abiotic components defined in the context of the aquarium?

• As living components that shape the environment

• As non-living components that shape the environment

• As components that provide food for fish

• As components that are only found in natural habitats

Which of the following is considered a biotic component in the aquarium?

• Fish

• Dissolved oxygen

• Natural wood

• Water

What role does natural wood play in the aquarium?

• It adds nutrients to the water

• It increases water temperature

• It provides a habitat for fish

• It filters the water

How does water quality affect fish diversity in the aquarium?

• Water quality has no effect on fish diversity

• Water quality and fish diversity are closely linked

• Lower water quality increases fish diversity

• Higher water quality decreases fish diversity

What is the relationship between carbon dioxide and floating plants in the aquarium?

• Carbon dioxide is used by floating plants for photosynthesis

• Floating plants release carbon dioxide

• Carbon dioxide is harmful to floating plants

• Floating plants do not interact with carbon dioxide

Why is dissolved oxygen important for fish in the aquarium?

• It provides nutrients for fish

• It keeps the water clear

• It is necessary for fish respiration

• It helps fish to digest food

What is the main conclusion about the interaction between abiotic and biotic factors?

• Abiotic factors are not important for biotic survival

• Biotic factors can survive without abiotic factors

• Abiotic factors provide nutrients and affect biotic survival

• Biotic factors provide nutrients to abiotic factors
