Food Chains and Food Webs

Front

What is a food chain?

Back

A series of organisms each dependent on the next as a source of food

Answer explanation

A food chain describes the relationship between organisms in an ecosystem, where each organism is a source of food for the next. This definition clearly matches the correct choice, highlighting the interdependence of species.

Front

A food web is:

Back

A complex network of interconnected food chains in an ecosystem

Answer explanation

A food web represents the complex interactions between various organisms in an ecosystem, showing how different food chains are interconnected, rather than a simple linear sequence or just energy flow.

Front

The diagram represents a simple food chain. The arrows in the diagram indicate the:

Back

direction of energy flow through a series of organisms

Answer explanation

The arrows in a food chain indicate the direction of energy flow through a series of organisms, showing how energy is transferred from one organism to another in the ecosystem.

Front

One path that energy could take through an ecosystem is called a ________________________.

Back

Food Chain

Answer explanation

One path that energy could take through an ecosystem is called a Food Chain. It illustrates the direct flow of energy from one organism to another, unlike a Food Web, which shows multiple interconnected paths.

Front

What happens if a species in a food chain goes extinct?

Back

It can disrupt the food chain and affect other species

Answer explanation

If a species in a food chain goes extinct, it can disrupt the food chain and affect other species that rely on it for food or ecological balance, leading to potential declines or increases in other populations.

Front

Organisms that eat both meat and plants are _______.

Back

omnivores

Answer explanation

Organisms that eat both meat and plants are called omnivores. Herbivores eat only plants, while carnivores eat only meat. Therefore, the correct answer is omnivores.

Front

Organisms that only eat meat are ______.

Back

carnivores

Answer explanation

Organisms that only eat meat are called carnivores. Unlike omnivores, which eat both plants and animals, and herbivores, which eat only plants, carnivores exclusively consume meat.

Front

In a food chain, what do we call the organism that makes its own food?

Back

Producer

Answer explanation

In a food chain, organisms that make their own food through processes like photosynthesis are called producers. They form the base of the food chain, unlike consumers, decomposers, or predators.

Front

Organisms that eat only plants are ______.

Back

herbivores

Answer explanation

Organisms that eat only plants are called herbivores. Carnivores eat other animals, omnivores eat both plants and animals, and food chains describe the flow of energy in ecosystems. Therefore, the correct answer is herbivores.

Front

What is the name for the organism that eats the producer? Options: primary consumer, secondary consumer, tertiary consumer, producer

Back

primary consumer

Answer explanation

The organism that eats the producer is called a primary consumer. Primary consumers are typically herbivores that directly consume plants, which are the producers in an ecosystem.
