Food Webs

What role do decomposers play in a food web?

• Decomposers break down dead and decaying material, returning nutrients to the soil and making them available for plants.

• Decomposers produce energy through photosynthesis for the food web.

• Decomposers are primary consumers that eat plants and convert them into energy.

• Decomposers are organisms that only feed on living plants.

What is the role of plants in a food web?

• Plants are consumers that eat other organisms.

• Plants are decomposers that break down dead matter.

• Plants are producers that convert sunlight into energy, forming the base of the food web.

• Plants are parasites that rely on other organisms for nutrients.

How do changes in one population affect a food web?

• They have no effect on the food web.

• They can cause a chain reaction, impacting other populations connected in the web.

• They only affect the population that is changing.

• They lead to the extinction of all species in the food web.

What is a producer in a food web?

• An organism that can make its own food through photosynthesis.

• A consumer that feeds on other organisms.

• A decomposer that breaks down dead matter.

• A predator that hunts for food.

What is the difference between a food chain and a food web?

• A food chain is a complex network of many food chains, while a food web is a linear sequence of organisms where each is eaten by the next.

• A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of many food chains.

• A food chain includes only herbivores, while a food web includes both herbivores and carnivores.

• A food chain represents the energy flow in an ecosystem, while a food web represents the nutrient cycle.

What is a primary consumer?

• An organism that eats producers, typically herbivores.

• An organism that produces its own food through photosynthesis.

• An organism that feeds on primary consumers.

• An organism that decomposes organic material.

What is an example of a decomposer?

• Millipede

• Eagle

• Oak Tree

• Daisy

Why are food webs important for ecosystems?

• They show the relationships between organisms and how energy and nutrients are cycled in an ecosystem.

• They only represent the predator-prey relationships.

• They are a simple way to categorize animals in an ecosystem.

• They illustrate the physical structure of habitats.

What happens when a habitat is destroyed?

• It can lead to an increase in biodiversity.

• It can disrupt the food web by decreasing the number of organisms that depend on that habitat.

• It has no significant impact on the ecosystem.

• It causes immediate recovery of the habitat.

What is the primary source of energy for almost all food webs?

• The moon

• The sun

• Geothermal energy

• Wind energy
