Feeding Relationships

What is a predator-prey relationship?

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

• A relationship where one organism provides protection to another organism

• A symbiotic relationship where both organisms benefit from each other

• A relationship where two organisms compete for the same resources

Give an example of a producer-consumer relationship in an ecosystem.

• Birds and rocks

• Trees and clouds

• Fish and bicycles

• Plants and herbivores

Explain the parasite-host relationship and provide an example.

• The relationship between a human and a pet dog

• An example of a parasite-host relationship is the relationship between a tapeworm and a human.

• The relationship between a tree and a bird

• The relationship between a lion and a zebra

What is the role of a primary producer in a food chain?

• They have no role in the food chain.

• They form the base of the food chain by producing their own food.

• They provide shelter for other organisms in the food chain.

• They hunt and consume other organisms for food.

Define primary consumer and give an example.

• Rabbit

• Tiger

• Elephant

• Lion

What is the difference between a primary consumer and a secondary consumer?

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

• Primary consumers are larger in size than secondary consumers.

• Primary consumers are carnivores, while secondary consumers are herbivores.

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

How do predator-prey relationships help in maintaining balance in an ecosystem?

• Controlling the population of prey species and preventing overgrazing or overpopulation

• Having no impact on the population of prey species

• Encouraging overgrazing and overpopulation of prey species

• Causing imbalance by increasing the population of predators

Explain the concept of energy transfer in a food chain.

• Energy transfer in a food chain is a result of weather patterns

• Energy transfer in a food chain occurs as organisms consume other organisms, transferring energy from one level to the next.

• Energy transfer in a food chain occurs through photosynthesis

• Energy transfer in a food chain happens through the exchange of genetic material

Why are primary producers considered the most important part of the food chain?

• They do not contribute to the energy flow in the ecosystem

• They are the least important for the balance of the food chain

• They provide food and energy for all other organisms in the ecosystem.

• They are the smallest organisms in the ecosystem

Discuss the impact of human activities on feeding relationships in an ecosystem.

• Feeding relationships in an ecosystem are not affected by human activities.

• Human activities can improve feeding relationships in an ecosystem.

• Human activities can disrupt feeding relationships by causing the decline or extinction of certain species.

• Human activities have no impact on feeding relationships in an ecosystem.
