Food Chain | MCQs

Explanation

• Tertiary consumers are animals that eat primary and secondary consumers.
• They are typically apex predators that have no natural predators in the wild and are at the top of their food chain.
• Examples of tertiary consumers include lions, sharks, bears, and humans.

Explanation

• Cat is a secondary consumer because it eats primary consumers (birds and mice).
• Which are herbivores that eat plants and plant products.

Explanation

• Carnivores are secondary consumers that eat primary consumers (herbivores).
• In this case, birds and mice are primary consumers (herbivores) that eat plants and plant products.
• Carnivores that eat birds and mice are secondary consumers.

Examples of carnivores that might eat birds and mice include:

• Hawks and owls (birds of prey)
• Foxes, wolves, and cats (mammals)
• Snakes and lizards (reptiles)

Explanation

Sheep and birds are primary consumers because they eat plants and plant products, such as grass, leaves, seeds, and fruits.

Explanation

In the absence of sunlight, the entire food chain would become inactive and collapse because:

• Plants and algae, the primary producers, cannot undergo photosynthesis and produce energy.
• Herbivores cannot feed on plants, and carnivores cannot feed on herbivores.
• The energy flow from producers to consumers would be disrupted, leading to a collapse of the food chain.

Explanation

• Carnivores are animals that eat only meat, primarily from other animals.
• Examples of carnivores include lions, tigers, bears, wolves, and sharks.

Explanation

Fire ants are red-colored insects.

A sting from a fire ant delivers a harmful substance, called venom, into your skin.
