Food Webs: Cycling of Matter and Flow of Energy

What is matter cycling in an ecosystem?

• The process of energy flow through an ecosystem.

• The movement and transformation of nutrients through living organisms and the environment.

• The interaction between different species in an ecosystem.

• The seasonal changes in an ecosystem's climate.

What is energy flow in an ecosystem?

• Energy flow refers to the transfer of energy from one organism to another through food consumption.

• Energy flow is the movement of water in an ecosystem.

• Energy flow describes the process of photosynthesis in plants.

• Energy flow is the cycle of nutrients in the soil.

What is the role of producers in a food web?

• Producers create energy through photosynthesis, forming the base of the food web.

• Producers consume other organisms for energy.

• Producers decompose organic matter in the ecosystem.

• Producers are the primary consumers in the food web.

What is the relationship between photosynthesis and cellular respiration?

• Photosynthesis produces oxygen and sugar, which are used in cellular respiration to release energy.

• Cellular respiration produces glucose, which is used in photosynthesis to create oxygen.

• Photosynthesis and cellular respiration are completely unrelated processes.

• Photosynthesis occurs only at night, while cellular respiration occurs during the day.

What is the role of decomposers in a food web?

• Decomposers break down dead organisms, recycling nutrients back into the ecosystem.

• Decomposers produce energy through photosynthesis.

• Decomposers are primary consumers that eat plants.

• Decomposers are organisms that hunt and kill other animals.

What is a food chain?

• A food chain is a linear sequence showing how energy and nutrients flow from one organism to another.

• A food chain is a circular pattern of energy transfer among organisms.

• A food chain is a complex web of interactions between multiple species.

• A food chain is a method of classifying different types of food.
