Exploring Food Chains and Webs

What is a food chain?

• A food chain is a sequence of organisms each dependent on the next as a source of food.

• A food chain is a method of cooking food.

• A food chain is a type of food recipe.

• A food chain is a list of ingredients for a dish.

Define a food web.

• A food web is a type of food that is eaten by humans.

• A food web is a diagram showing the life cycle of a plant.

• A food web is a network of feeding relationships among various organisms in an ecosystem.

• A food web is a single linear chain of organisms.

What role do producers play in a food chain?

• Producers are the primary consumers in a food chain.

• Producers rely on other organisms for energy.

• Producers are the top predators in a food chain.

• Producers convert sunlight into energy and form the base of the food chain.

Give an example of a primary consumer.

• Grasshopper

• Deer

• Rabbit

• Frog

What is a secondary consumer?

• An organism that produces its own food.

• An organism that eats plants directly.

• An organism that feeds on decomposers.

• An organism that eats primary consumers in a food chain.

How do decomposers fit into the food chain?

• Decomposers are primary producers in the food chain.

• Decomposers only consume living plants and animals.

• Decomposers recycle nutrients and support the food chain by breaking down dead matter.

• Decomposers are at the top of the food chain.

Explain the difference between herbivores and carnivores.

• Herbivores eat plants; carnivores eat animals.

• Herbivores eat both plants and animals; carnivores only eat plants.

• Herbivores are larger than carnivores; carnivores are smaller.

• Herbivores have sharp teeth; carnivores have flat teeth.

What is an apex predator?

• An apex predator is a top predator with no natural enemies.

• Apex predators are always herbivores.

• Apex predators are known for their ability to fly long distances.

• An apex predator is the largest animal in its habitat.

How does energy flow through a food chain?

• Energy flows only from consumers to producers.

• Energy flows from producers to consumers in a food chain, with energy loss at each trophic level.

• Energy is lost only at the producer level.

• Energy is constant at all trophic levels.

What happens to energy as it moves up the food chain?

• Energy increases as it moves up the food chain.

• Energy decreases as it moves up the food chain.

• Energy is completely transferred to the top predator.

• Energy remains constant as it moves up the food chain.
