Unit 1 Food Webs

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that shows how energy and nutrients flow through an ecosystem.

Front

What role do producers play in a food web?

Back

Producers, such as plants, create their own food through photosynthesis and form the base of the food web.

Front

What are consumers in a food web?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

How does energy flow in a food chain?

Back

Energy flows from producers to consumers and then to decomposers, with each level representing a trophic level.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

Front

What is the difference between herbivores, carnivores, and omnivores?

Back

Herbivores eat plants, carnivores eat other animals, and omnivores eat both plants and animals.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation of the energy available at each trophic level in an ecosystem.

Front

Why are there fewer top predators in a food web?

Back

Top predators are fewer in number because they require a larger amount of energy, which limits their population size.
