What is a food chain?
A food chain is a sequence of organisms where each is eaten by the next in the chain.
A food chain is a diagram showing food prices in a market.
A food chain is a type of cooking method.
A food chain is a list of ingredients for a recipe.
Name the first link in a food chain.
Herbivore
Decomposer
Carnivore
Producer (e.g., plants)
What role do producers play in a food chain?
Producers convert sunlight into energy and form the base of the food chain.
Producers are consumers that eat plants.
Producers are organisms that decompose organic matter.
Producers rely on other organisms for energy.
Give an example of a primary consumer.
rabbit
snake
hawk
deer
What is a secondary consumer?
An organism that produces its own food.
An organism that eats plants.
An organism that eats primary consumers.
An organism that decomposes organic matter.
How do decomposers fit into a food chain?
Decomposers recycle nutrients and complete the food chain by breaking down dead organisms.
Decomposers are primary producers in the food chain.
Decomposers are at the top of the food chain.
Decomposers only consume living plants and animals.
Explain the term 'trophic level'.
Trophic level indicates the age of an organism.
Trophic level refers to the habitat where an organism lives.
Trophic level is the total biomass of an ecosystem.
Trophic level refers to the position an organism occupies in a food chain, defined by its role in energy transfer.
What happens if one species in a food chain is removed?
The food chain will remain unaffected and continue as normal.
All species will thrive without competition from the removed species.
The removed species will quickly be replaced by another species.
The ecosystem may become unbalanced, leading to overpopulation or extinction of other species.
Why are food chains important for ecosystems?
Food chains are solely based on plant growth.
Food chains have no impact on the environment.
Food chains are only important for human consumption.
Food chains are important for ecosystems because they demonstrate the interdependence of organisms and the flow of energy and nutrients.
Describe how energy flows through a food chain.
Energy is recycled within the same level of consumers.
Energy flows from producers to consumers and then to decomposers in a food chain.
Decomposers are the primary source of energy in a food chain.
Energy flows only from consumers to producers.
