Monday Checkup

What is a food chain?

• A diagram showing where animals live

• A diagram showing how energy is transferred between organisms

• A diagram showing how plants grow

• A diagram showing all organisms in an ecosystem

Why is a food web more realistic than a food chain?

• It shows only one feeding relationship

• It shows organisms eating only plants

• It shows many linked feeding relationships

• It has fewer arrows

In a food chain, arrows always show:

• where organisms move

• which organism is bigger

• the direction of energy transfer

• the direction of oxygen flow

Which organism is a producer?

• Fox

• Grass

• Snake

• Frog

Which pair is correctly matched?

• Predator – eaten organism

• Prey – hunts other animals

• Decomposer – breaks down dead material

• Carnivore – eats plants

A herbivore eats:

• animals

• plants

• decomposers

• sunlight

If the producer population decreases, what happens first?

• Carnivores increase

• Herbivores increase

• Herbivores decrease

• Decomposers disappear

If herbivores decrease, what is the most likely effect on carnivores?

• Carnivores increase

• Carnivores decrease

• Carnivores are not affected

• Producers increase

Which situation shows interdependence?

• Plants growing taller

• A predator depending on prey for food

• An animal changing colour

• Water evaporating

Which sentence best defines interdependence?

• Organisms depend on each other to survive.

• Organisms live independently without any help.

• Interdependence means plants grow taller over time.

• Interdependence is when water evaporates from surfaces.
