What is a predator-prey relationship?

• A relationship where two organisms benefit from each other

• A biological interaction where one organism hunts and consumes another organism

• A type of symbiotic relationship where one organism is harmed and the other is unaffected

• A relationship where two organisms compete for the same resources

Give an example of a predator-prey relationship.

• Rabbit eating grass

• Fish swimming in the ocean

• Lion hunting a zebra

• Bird building a nest

What is the role of producers in an ecosystem?

• Producers consume other organisms for energy.

• Producers convert sunlight into energy through photosynthesis.

• Producers are responsible for regulating the climate.

• Producers have no role in an ecosystem.

What are decomposers and what is their role in the ecosystem?

• Decomposers have no role in the ecosystem and do not affect the nutrient cycle.

• Decomposers hunt and consume other organisms, reducing the nutrient levels in the soil.

• Decomposers break down dead or decaying organisms and organic matter, recycling nutrients back into the soil.

• Decomposers create new organisms and organic matter, adding nutrients to the soil.

Explain the concept of energy flow in a food chain.

• Energy is transferred through the air in a food chain

• Energy is transferred from one organism to another through the consumption of food.

• Energy is only transferred from plants to animals in a food chain

• Energy is created by the organisms in a food chain

What is the difference between a primary consumer and a secondary consumer in a food chain?

• Primary consumers feed on producers, while secondary consumers feed on primary consumers.

• Primary consumers feed on secondary consumers, while secondary consumers feed on producers.

• Primary consumers feed on rocks, while secondary consumers feed on air.

• Primary consumers are plants, while secondary consumers are animals.

What is symbiosis?

• A type of rock formation

• A close and long-term interaction between different biological species.

• A type of weather phenomenon

• A form of transportation

Provide an example of mutualism in a symbiotic relationship.

• Lions and zebras

• Cats and mice

• Bees and flowers

• Sharks and remoras

How do human activities impact ecosystems?

• Human activities only benefit ecosystems

• Ecosystems are not affected by human activities

• Human activities can impact ecosystems through pollution, deforestation, overfishing, and habitat destruction.

• Human activities have no impact on ecosystems

Give an example of how deforestation affects an ecosystem.

• Decrease in habitat for many species, increased soil erosion, and improved biodiversity

• Loss of habitat for many species, soil erosion, disruption of the water cycle, and loss of biodiversity

• Increase in habitat for many species, improved soil quality, and enhanced water cycle

• No impact on habitat for species, no change in soil erosion, and no effect on the water cycle
