Food Chain & Web Practice

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, starting from producers to various levels of consumers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What role do producers play in a food chain?

Back

Producers, like plants, convert sunlight into energy through photosynthesis and form the base of the food chain.

Front

What is the primary source of energy for most food chains?

Back

The primary source of energy for most food chains is the Sun.

Front

What happens to the populations of organisms after a wildfire?

Back

After a wildfire, the populations of meadow plants and rabbits would likely decrease due to habitat destruction.

Front

What is the role of consumers in a food chain?

Back

Consumers are organisms that eat other organisms for energy; they can be herbivores, carnivores, or omnivores.

Front

How does energy flow in a food chain?

Back

Energy flows from the Sun to producers, then to primary consumers, and continues to higher-level consumers.

Front

What might happen if a key species is removed from a food web?

Back

Removing a key species can disrupt the balance of the ecosystem, leading to population increases or decreases in other species.

Front

What is a herbivore?

Back

A herbivore is an animal that primarily eats plants.

Front

What is a carnivore?

Back

A carnivore is an animal that primarily eats other animals.
