Science Super Quizizz

Henry, Eesha, and Kiara are studying different ecosystems for their science project. According to them, what is the primary function of the ecosystem they are studying?

• To provide habitat for a single species

• To study the minerals and rocks

• To facilitate interactions among living organisms and their environment

• To define a specific area with diverse living organisms

Answer explanation

An ecosystem is a network of interactions among living organisms and their environment.

Biotic components in an ecosystem include:

• Soil and water

• Sunlight and temperature

• Plants and animals

• Air and rocks

Answer explanation

Biotic components in an ecosystem refer to plants and animals, which interact and depend on each other for survival.

Which adaptation helps an animal survive in a cold climate?

• Large ears

• Thin fur

• Hibernation

• Shedding skin

Answer explanation

Thin fur is an adaptation that helps animals survive in a cold climate by providing insulation and reducing heat loss. It helps them retain body heat and stay warm.

The term used to describe all the populations in a specific area interacting with each other is:

• Ecosystem

• Community

• Habitat

• Biosphere

Answer explanation

The term used to describe all the populations in a specific area interacting with each other is 'Community'.

Decomposers in an ecosystem are responsible for:

• Producing energy for plants

• Breaking down dead organisms

• Controlling the population of consumers

• Photosynthesis

Answer explanation

Decomposers in an ecosystem break down dead organisms, aiding in nutrient recycling and maintaining ecosystem balance.

A food chain typically begins with:

• Decomposers

• Producers

• Consumers

• Predators

Answer explanation

A food chain typically begins with producers, which are organisms that can produce their own food through photosynthesis or chemosynthesis.

Changing any part of a food chain can:

• Lead to a decrease in energy transfer

• Have no effect on the rest of the chain

• Enhance the chain's stability

• Disrupt only the producers

Answer explanation

Changing any part of a food chain can have no effect on the rest of the chain. This means that altering one component of the chain does not impact the other organisms or the flow of energy within the chain.

Matter cycling in the environment promotes:

• Increased pollution

• Sustainability

• Reduced biodiversity

• Soil erosion

Answer explanation

Matter cycling in the environment promotes sustainability, ensuring long-term ecological balance and resource availability.

Biotic factors limiting the number of organisms in an ecosystem could include:

• Availability of food

• Sunlight intensity

• Oxygen concentration

• Precipitation patterns

Answer explanation

Biotic factors, such as the availability of food, can limit the number of organisms in an ecosystem.

Strategies to maintain balance in ecosystems after agriculture impact could involve:

• Introducing invasive species

• Decreasing biodiversity

• Implementing sustainable farming practices

• Increasing the use of pesticides

Answer explanation

To maintain balance in ecosystems after agriculture impact, implementing sustainable farming practices is crucial.
