Ecosystem Roles and Food Webs

The video tutorial, led by Suzanne at Utah's Huggle Zoo, explores the concepts of food chains and food webs. It explains how energy flows through ecosystems, starting from the Sun, moving through producers like plants, and then to various levels of consumers, including herbivores, omnivores, and carnivores. The tutorial also highlights the role of decomposers in recycling nutrients and the complexity of food webs. The importance of maintaining balance in ecosystems is emphasized, with examples of how disruptions can affect the entire system.

What is the primary source of energy for all food chains on Earth?

• The Wind

• The Ocean

• The Sun

• The Moon

What do plants use to create energy and food?

• Rain and minerals

• Wind and soil

• Moonlight and oxygen

• Sunlight, carbon dioxide, and water

Which of the following is an example of a primary consumer?

• Millipede

• Jackal

• Giraffe

• Lion

What adaptation helps herbivores like giraffes eat plants?

• Sharp claws

• Flat teeth

• Forward-facing eyes

• Long tails

Which animal is an example of a secondary consumer?

• Giraffe

• Meerkat

• Lion

• Millipede

What type of consumer is a jackal?

• Decomposer

• Carnivore

• Omnivore

• Herbivore

What role do decomposers play in the ecosystem?

• They produce energy from the Sun

• They consume primary consumers

• They break down dead matter

• They hunt tertiary consumers

Which of the following is a decomposer?

• Millipede

• Giraffe

• Jackal

• Lion

What happens if a drought reduces the number of plants in an ecosystem?

• Herbivores thrive

• Carnivores have more food

• The entire food web is affected

• Decomposers stop working

Why is it important to maintain balance in a food web?

• To keep energy flowing through the ecosystem

• To prevent overpopulation of producers

• To make sure all animals become carnivores

• To ensure decomposers have enough to eat
