What is a food chain?

• A food chain is a type of necklace made of edible items.

• A food chain is a series of organisms where each organism eats the one below it, transferring energy from one level to the next.

• A food chain is a popular dance move involving imitating animals.

• A food chain is a mathematical equation used to calculate calories in a meal.

Explain the concept of energy flow in an ecosystem.

• Energy flow in an ecosystem only occurs between organisms within the same trophic level.

• Energy flow in an ecosystem involves the transfer of matter from consumers to producers.

• Energy flow in an ecosystem is a linear process with no loss of energy.

• Energy flow in an ecosystem involves the transfer of energy from producers to consumers through food chains and webs, with energy being lost as heat at each trophic level.

Name two types of producers in an ecosystem.

• plants, algae

• animals

• fungi

• bacteria

How do consumers obtain energy in a food chain?

• Absorbing sunlight directly

• Using photosynthesis

• Consuming other organisms

• Drinking water

What role do decomposers play in an ecosystem?

• Creating new nutrients in the ecosystem

• Maintaining the oxygen levels in the ecosystem

• Regulating the population of predators

• Recycling nutrients back into the ecosystem

Describe the relationship between producers and consumers in a food chain.

• Producers create food for consumers to consume in a food chain.

• Producers and consumers do not interact in a food chain.

• Consumers create food for producers in a food chain.

• Producers consume food created by consumers in a food chain.

Give an example of a primary producer.

• rock

• plant

• bacteria

• cloud

Why are decomposers important in nutrient cycling?

• Decomposers are important in nutrient cycling because they disrupt the food chain

• Decomposers are important in nutrient cycling because they break down organic matter and release nutrients back into the ecosystem.

• Decomposers are important in nutrient cycling because they reduce biodiversity

• Decomposers are important in nutrient cycling because they increase pollution

How does energy flow through a food chain?

• Energy flows from producers to herbivores, then to carnivores, and finally to decomposers in a food chain.

• Energy flows from herbivores to producers in a food chain.

• Energy flows from decomposers to herbivores in a food chain.

• Energy flows from carnivores to producers in a food chain.

What happens if there is a disruption in the food chain?

• Enhanced ecosystem stability

• Imbalances in ecosystems, affecting species population and biodiversity.

• Increased biodiversity and species population

• No impact on the environment
