What is a food chain?

• A diagram showing the water cycle

• A representation of the carbon cycle

• A complex network of interconnected food sources

• A simple model showing energy transfer from one organism to another

How does a food web differ from a food chain?

• A food web only includes plants

• A food web shows multiple interconnected food chains

• A food web is a simpler model than a food chain

• A food web shows a single path of energy flow

What is a keystone species?

• A species that is always a primary consumer

• A species that only eats plants

• A species that has a large impact on its ecosystem

• A species that is at the top of the food chain

What is the 10% rule in energy pyramids?

• Only 10% of the energy is lost at each trophic level

• Only 10% of the energy is transferred to the next trophic level

• 10% of the energy is used for growth

• 10% of the energy is stored as fat

What is an autotroph?

• An organism that consumes other organisms for energy

• An organism that lives in water

• An organism that produces its own energy

• An organism that decomposes dead matter

What is the primary consumer in a food chain?

• The first organism to eat the producer

• The top predator in the food chain

• The organism that produces its own energy

• The second organism in the food chain

What does biomass refer to?

• The number of organisms in an ecosystem

• The energy content of an organism

• The dry weight of an organism

• The total weight of water in an organism

Why is water not included in biomass measurements?

• Water is not important for energy transfer

• Water is not transferred between organisms

• Water evaporates too quickly

• Water is not part of the organism's structure

What is the main difference between an energy pyramid and a biomass pyramid?

• Energy pyramids measure energy in joules, biomass pyramids measure mass in grams

• Energy pyramids include water content, biomass pyramids do not

• Energy pyramids show the number of organisms, biomass pyramids show energy flow

• Energy pyramids are used for plants, biomass pyramids are used for animals
