Food Web

What is a producer in an ecosystem food web?

• A type of decomposer that breaks down dead organic matter

• A predator that hunts other animals for food

• An organism, typically a plant, that produces its own food through photosynthesis.

• An organism that consumes other organisms for energy

How does the presence of an apex predator affect a food web compared to its impact on a food chain?

• In a food web, an apex predator helps maintain species diversity by controlling populations, while in a food chain, it ends the sequence of consumption.

• An apex predator regulates energy flow in a food web, whereas in a food chain, it dictates the nutrient cycle.

• In a food web, an apex predator is part of multiple feeding levels, while in a food chain, it is seen as the final consumer.

• A food web with an apex predator shows complex interactions among organisms, while a food chain with an apex predator highlights a straightforward energy path.

Describe how energy flows in an ecosystem, focusing on the role of an apex predator.

• Energy flows from the soil to the air, bypassing apex predators in an ecosystem.

• Energy flows from producers to apex predators through a food chain or food web in an ecosystem.

• Energy flows from the sun to the moon, ignoring the presence of apex predators in an ecosystem.

• Energy flows from consumers to producers, with apex predators disrupting this flow in an ecosystem.
