Reactions and Food Chain Basics

What is a reversible reaction?

• A reversible reaction is a chemical reaction where the products can react to produce the original reactants.

• A reversible reaction is a chemical reaction that involves irreversible changes.

• A reversible reaction is a chemical reaction that only occurs in one direction.

• A reversible reaction is a chemical reaction where the products cannot react to produce the original reactants.

Give an example of a reversible reaction.

• Combustion of wood

• Formation of water from hydrogen and oxygen gas

• Rusting of iron

• Photosynthesis

What is an irreversible reaction?

• An irreversible reaction is a chemical reaction where the products cannot revert back to the original reactants.

• An irreversible reaction is a chemical reaction that can be easily reversed.

• An irreversible reaction is a chemical reaction that does not involve any energy changes.

• An irreversible reaction is a chemical reaction that only occurs in living organisms.

Provide an example of an irreversible reaction.

• Freezing of water

• Boiling water

• Photosynthesis in plants

• Combustion of wood

What is a food chain?

• A food chain is a popular dance move involving food-related gestures.

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

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

• A food chain is a series of organisms where each organism is eaten by the next one in the chain.

Explain the concept of a food web.

• A food web is a single linear chain of organisms.

• A food web is a complex network of interconnected food chains.

• A food web consists of only two trophic levels.

• A food web is a static structure that never changes.

How do producers contribute to the food chain?

• Producers convert sunlight into energy through photosynthesis.

• Producers do not play a role in the food chain

• Producers consume energy from other organisms

• Producers rely on herbivores for food

What role do consumers play in a food chain?

• Consumers feed on other organisms in the food chain.

• Consumers produce food in a food chain.

• Consumers only consume non-living things in a food chain.

• Consumers are not part of the food chain.

Name one decomposer in a food chain.

• Plants

• Worms

• Bacteria

• Fungi

Why is it important to maintain balance in a food chain?

• To ensure the stability of ecosystems, prevent overpopulation or extinction of species, and promote biodiversity.

• To disrupt the natural order, encourage species dominance, and limit biodiversity
