Food Chains

What is a food chain?

• A food chain is a sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

• A food chain is a type of food that is prepared in a specific way.

• A food chain is a list of all the animals in a particular habitat.

• A food chain is a method of cooking food using heat.

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

• The moon

• The sun

• Geothermal energy

• Wind energy

What is an example of a food chain?

• Grass -> Rabbit -> Fox

• Water -> Fish -> Eagle

• Sun -> Plant -> Caterpillar

• Soil -> Worm -> Bird

What is the significance of the sun in a food chain?

• The sun provides the energy that fuels the entire food chain through photosynthesis.

• The sun is a source of water for plants in the food chain.

• The sun helps in the decomposition of organic matter in the food chain.

• The sun regulates the temperature of the earth, affecting food chain dynamics.

What is the difference between herbivores and carnivores?

• Herbivores eat plants, while carnivores eat other animals.

• Herbivores are larger than carnivores.

• Carnivores only eat fruits and vegetables.

• Herbivores can live in water, while carnivores cannot.

What is a tertiary consumer?

• An organism that eats primary consumers, like a rabbit that eats grass.

• An organism that eats secondary consumers, like a hawk that eats snakes.

• An organism that produces its own food, like a plant.

• An organism that decomposes dead matter, like a fungus.

Why are insects considered consumers?

• They produce their own food through photosynthesis.

• They eat plants or other animals for energy.

• They are decomposers that break down dead matter.

• They primarily feed on fungi.

What is a secondary consumer?

• An organism that produces its own food through photosynthesis.

• An organism that eats primary consumers, such as a snake that eats a mouse.

• An organism that decomposes dead matter and recycles nutrients.

• An organism that feeds on plants and is at the base of the food chain.

Give an example of a primary consumer.

• Rabbit

• Lion

• Eagle

• Shark

What are producers in a food chain?

• Organisms that consume other organisms for energy.

• Organisms that make their own food through photosynthesis, such as plants.

• Organisms that decompose dead matter.

• Organisms that rely on external sources for food.
