EXAM: FOOD WEB/ADAPTATIONS

Front

What is a food web?

Back

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

Front

Define 'producer' in an ecosystem.

Back

Producers are organisms, typically plants, that create their own food through photosynthesis and serve as the base of the food web.

Front

What role do consumers play in a food web?

Back

Consumers are organisms that eat other organisms (plants or animals) to obtain energy. They can be herbivores, carnivores, or omnivores.

Front

What is a decomposer?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

Front

Explain the concept of adaptation.

Back

Adaptation is a characteristic or trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is the difference between a herbivore and a carnivore?

Back

Herbivores are animals that primarily eat plants, while carnivores are animals that primarily eat other animals.

Front

Give an example of a mutualistic relationship in a food web.

Back

An example of mutualism is the relationship between bees and flowering plants, where bees pollinate the plants while obtaining nectar for food.

Front

What is an apex predator?

Back

An apex predator is a predator at the top of the food chain that has no natural enemies, such as lions or great white sharks.

Front

How do energy pyramids relate to food webs?

Back

Energy pyramids illustrate the flow of energy through different trophic levels in a food web, showing that energy decreases as it moves up the pyramid.

Front

What is the significance of biodiversity in a food web?

Back

Biodiversity increases the resilience of an ecosystem, allowing it to better withstand changes and disturbances.
