Ecosystem Food Web 5th Grade TEK

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

Explain the role of an apex predator in an ecosystem.

• Apex predators maintain the balance of populations in the ecosystem by controlling the numbers of other species.

• Apex predators reduce the amount of oxygen in the ecosystem.

• Apex predators create new species in the ecosystem.

• Apex predators increase the acidity of the ecosystem.

Define a food chain and provide an example that ends with an apex predator.

• A food chain is a series of restaurants where each restaurant serves a different type of cuisine.

• A food chain is a series of animals where each animal is eaten by the previous one in the chain.

• A food chain is a series of organisms where each organism is eaten by the next one in the chain. An example of a food chain is grass (producer) being eaten by a grasshopper (primary consumer), which is then eaten by a frog (secondary consumer), and finally eaten by a snake (tertiary consumer), which is then eaten by an eagle (apex predator).

• A food chain is a series of grocery stores where each store sells different types of food.

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.

Differentiate between the roles of apex predators and other components in an ecosystem.

• Apex predators are inorganic, while other components are organic.

• Apex predators are always visible, while other components are invisible.

• Apex predators do not interact with other components, while other components do.

• Apex predators regulate population and maintain ecosystem balance, while other components include biotic factors like plants and animals, as well as abiotic factors like sunlight, water, air, and soil.

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.
