Food Chains and Food Webs

What is a food chain?

• A food chain is a network of organisms where each organism consumes multiple food sources.

• A food chain is a linear sequence of organisms where each organism is the food source for the next organism in the chain.

• A food chain is a circular sequence of organisms where each organism is the food source for the previous organism in the chain.

• A food chain is a process where organisms convert sunlight into energy through photosynthesis.

What is a food web?

• A food web is a diagram that shows the physical structure of an ecosystem.

• A food web is a list of all the foods that an organism eats.

• A food web is a diagram that shows the feeding relationships between different organisms in an ecosystem.

• A food web is a term used to describe the process of photosynthesis in plants.

What is a producer in a food chain or food web?

• An organism that relies on other organisms for food.

• An organism that decomposes dead organisms for food.

• An organism that can produce its own food through photosynthesis or chemosynthesis.

• An organism that consumes other organisms for food.

What is a consumer in a food chain or food web?

• An organism that obtains energy from inorganic sources.

• An organism that obtains energy from the sun.

• An organism that produces energy by consuming other organisms.

• An organism that obtains energy by consuming other organisms.

What is a decomposer in a food chain or food web?

• An organism that consumes other organisms for energy.

• An organism that helps in the process of pollination.

• An organism that produces its own food through photosynthesis.

• An organism that breaks down dead organic matter

Give an example of a food chain in a forest ecosystem.

• plants -> deer -> wolves -> bears

• plants -> mice -> snakes -> hawks

• plants -> insects -> birds -> predators

• plants -> rabbits -> foxes -> coyotes

What is the role of a producer in a food chain or food web?

• The role of a producer is to consume other organisms in the food chain or food web.

• The role of a producer is to break down organic matter in the food chain or food web.

• The role of a producer is to convert sunlight or chemical energy into food for other organisms in the food chain or food web.

• The role of a producer is to regulate the population of other organisms in the food chain or food web.

What are the different types of consumers in a food chain or food web?

• herbivores, carnivores, and omnivores

• producers, decomposers, and scavengers

• predators, prey, and parasites

• primary consumers, secondary consumers, and tertiary consumers

Why are decomposers important in a food chain or food web?

• Decomposers help in the process of photosynthesis.

• Decomposers break down dead organisms and organic waste, releasing nutrients back into the ecosystem.

• Decomposers help in the reproduction of organisms in the food web.

• Decomposers provide energy to the producers in the food chain.
