Feeding relationships

What is a food web?

• A food web is a type of spider web made of food particles.

• A food web is a type of fishing net used to catch food in the ocean.

• A food web is a cooking website that specializes in web-based recipes.

• A food web is a system of interlocking and interdependent food chains showing the flow of energy and nutrients through an ecosystem.

Define a producer in a feeding relationship.

• An organism that consumes other organisms for food.

• An organism that produces its own food through photosynthesis or chemosynthesis.

• An organism that breaks down dead organic matter for food.

• An organism that lives in a symbiotic relationship with another organism for food.

Give an example of a consumer in a feeding relationship.

• Rabbit

• Tree

• Lion

• Sunflower

Explain the role of decomposers in an ecosystem.

• Decomposers break down dead organisms and organic matter, releasing nutrients back into the ecosystem.

• Decomposers reduce the amount of nutrients in an ecosystem.

• Decomposers create new organisms in an ecosystem.

• Decomposers primarily feed on live organisms in an ecosystem.

How are producers different from consumers in a food web?

• Producers are always larger in size than consumers.

• Producers are always herbivores, while consumers can be carnivores or omnivores.

• Producers rely on other organisms for food, while consumers make their own food.

• Producers make their own food, while consumers rely on other organisms for food.

Name a primary consumer in a food chain.

• Herbivore

• Omnivore

• Carnivore

• Decomposer

Why are decomposers important in a food chain?

• Decomposers create imbalances in the ecosystem

• Decomposers break down dead organisms and waste, recycling nutrients in the ecosystem.

• Decomposers contribute to the growth of primary producers

• Decomposers reduce nutrient availability in the food chain

What happens if there is a disruption in the food web?

• Enhanced ecosystem stability

• Imbalances in the ecosystem, affecting population sizes of species.

• Decreased competition among species

• Increased biodiversity

Describe the flow of energy in a food chain.

• Energy flows from decomposers to carnivores to herbivores in a food chain.

• Energy flows from consumers to producers in a food chain.

• Energy flows from carnivores to herbivores to producers in a food chain.

• Energy flows from producers to herbivores to carnivores to decomposers in a food chain.

How do decomposers help recycle nutrients in an ecosystem?

• Decomposers absorb nutrients from the ecosystem

• Decomposers reduce the nutrient levels in the ecosystem

• Decomposers break down dead organisms and organic matter, releasing nutrients back into the ecosystem.

• Decomposers create new organisms to recycle nutrients
