Food Webs

What happens to a food web if a producer is removed?

• The food web remains unaffected as consumers can find alternative food sources.

• The consumers that rely on it for food may decrease in number, affecting the entire food web.

• The producer's removal leads to an increase in the population of other producers.

• The food web becomes more stable and balanced without the producer.

How does energy flow in a food web?

• Energy flows from consumers to producers and then to decomposers.

• Energy flows from producers to consumers and then to decomposers, forming a cycle of energy transfer.

• Energy flows in a linear path from producers to decomposers only.

• Energy is stored in the soil and does not flow through the food web.

What is a producer in a food web?

• An organism that consumes other organisms for energy.

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

• An organism that decomposes dead matter.

• An organism that relies on other organisms for food.

How do decomposers contribute to a food web?

• They produce energy for the food web.

• They recycle nutrients back into the soil, making them available for producers, thus supporting the entire food web.

• They consume primary consumers and reduce their population.

• They compete with producers for sunlight and water.

What is a consumer in a food web?

• A producer that creates energy from sunlight.

• An organism that eats other organisms (plants or animals) to obtain energy.

• A decomposer that breaks down dead matter.

• A type of plant that does not require sunlight.

What impact does a wildfire have on a food web?

• A wildfire has no effect on the food web.

• A wildfire can lead to an increase in all populations within the food web.

• A wildfire can destroy habitats, leading to a decrease in certain populations and an increase in others, disrupting the balance of the food web.

• A wildfire only affects plant life, leaving animal populations unchanged.

What is a food web?

• A simple chain of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

• A diagram that shows the population of different species in an area.

• A type of food chain that only includes plants.

What is a trophic level?

• A position in a food web defined by how an organism obtains its energy.

• A measure of the size of an organism in an ecosystem.

• The total number of species in a habitat.

• The rate at which energy is transferred between organisms.

What is the significance of biodiversity in a food web?

• Biodiversity increases the stability of a food web, allowing it to better withstand changes and disturbances.

• Biodiversity decreases the number of species in a food web, making it less complex.

• Biodiversity has no impact on the food web's stability or resilience.

• Biodiversity only affects the primary producers in a food web.

What is a decomposer?

• An organism that produces energy through photosynthesis.

• An organism that breaks down dead organic material, returning nutrients to the soil.

• A type of plant that grows in water.

• An animal that feeds on living organisms.
