Producers, Consumers, and Decomposers

What are decomposers?

• Organisms that produce energy through photosynthesis.

• Organisms, like fungi and bacteria, that break down dead organisms and recycle nutrients back into the soil.

• Organisms that consume plants and animals for energy.

• Organisms that live in extreme environments and do not require oxygen.

What is the role of decomposers in an ecosystem?

• Decomposers help break down dead matter, returning nutrients to the soil and supporting new plant growth.

• Decomposers primarily produce energy through photosynthesis.

• Decomposers compete with plants for sunlight and nutrients.

• Decomposers are responsible for pollinating flowers and plants.

What are consumers?

• Consumers are living things that eat other living things for energy.

• Consumers are organisms that produce their own food through photosynthesis.

• Consumers are animals that only eat plants.

• Consumers are living things that decompose organic material.

What do omnivores eat?

• Only plants

• Only animals

• Both plants and animals

• Neither plants nor animals

What happens to energy as it moves up the food chain?

• It increases, providing more energy for each successive consumer.

• It remains constant, with the same amount of energy available at each level.

• It decreases, meaning less energy is available for each successive consumer.

• It fluctuates randomly, with no specific trend.

What is photosynthesis?

• Photosynthesis is the process by which plants use sunlight to make their own food.

• Photosynthesis is the method by which animals convert food into energy.

• Photosynthesis is the way in which plants absorb water from the soil.

• Photosynthesis is the technique used by plants to reproduce sexually.

What are producers?

• Living things that make their own food through photosynthesis.

• Animals that consume other living things for energy.

• Microorganisms that decompose organic matter.

• Fungi that absorb nutrients from their environment.

What is a food web?

• A simple linear sequence of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem.

• A type of food chain that only includes plants.

• A diagram that shows the energy flow in a single species.

Give an example of a producer.

• A tree

• A rabbit

• A mushroom

• A fish

What do herbivores eat?

• Only plants.

• Only meat.

• Both plants and meat.

• Insects and small animals.
