Food Web Jeopardy

Food Chain

100

Name the levels of a food chain in order.

Producer, Primary Consumer, Secondary Consumer, Tertiary Consumer, Decomposer.

200

What level of the food chain contains the most amount of energy?

Producers will contain the most amount of energy, as they make their own energy using photosynthesis.

300

Name one Producer, one Herbivore, one Omnivore, one Carnivore, and one Decomposer.

( Answers will vary, but here are my examples. ) Tree, Mouse, Human, Wolf, and Fungi.

400

An Omnivore can be all three consumers, primary, secondary, and tertiary. How is that possible?

Omnivores can eat both meat and plants. Primary Consumers eat plants, or Producers, which Omnivores can do. Secondary Consumers eat meat, or Primary Consumers, which Omnivores can also do. Tertiary Consumers eat meat, or Secondary Consumers, which Omnivores can do.

500

Would a human who eats only plants be considered an Herbivore, or an Omnivore? Why?

It would still be considered an Omnivore, because they are still part of an Omnivore population, despite their plant only diet. They could also go and eat meat if they chose to.

Affect on Biome and Organisms

100

How does removing an organism from its habitat affect the remaining organisms in the biome?

That organism could have been the prey to another organism or organisms, meaning they either die off or have to find another food source, or it could have been the predator to one or more organisms, allowing that prey organism to overpopulate slightly more than before, especially if it was the only organism that ate that prey organism.

200

How does the climate (weather and precipitation) support the organisms in a biome?

A certain type of weather or a certain amount of precipitation could have a positive or negative affect on organisms in a certain biome. Organisms are made to survive in a certain biome, or in some cases biomes, and biomes usually have specific types of weather or a certain amount of precipitation, meaning that organism would be able to survive in that biome. If you were to move an organism from their home biome to another that they couldn't survive in, they would most likely die.

300

How does a change in a population’s numbers (increase or decrease) affect the remaining organisms in the biome?

If a certain population increases in numbers, it could overpopulate and take over, taking more and more food from a source, that could be supporting another population of animals, and force the other population to move or die off. The more the numbers increase, the harder it becomes to find food for both themselves and other organisms, so eventually, they would start to die too. With a decrease, that population could allow another population to increase or decrease as well. If they were a predator, they would allow another population to increase, and if they were prey, they would force another population to decrease, move, or find another food source.

400

How does adding an organism to an ecosystem affect the remaining organisms in the biome?

Say I added a bear, which is a tertiary consumer, to a temperate forest biome, one that bears didn't live in already. Seeing as the bear would be on the top of the food chain, it would become a predator and eat prey that could've been another species food source. Say it was a herd of deer, and both the bear and the wolf pack were eating them. Eventually the deer herd would be killed off and eaten by the wolf pack and bear, forcing both to find another food source. It would end up with a lot more prey and food sources being used up, and making it harder and harder for other animals to survive the the decreased food source.

500

How does the carbon and nitrogen cycle affect a biome and the organisms in it?

If there's too much carbon in the ecosystem, it could damage the biome and the organisms in it. With only one thing able to take carbon dioxide out of the air and turn it into oxygen, and so many different things putting carbon dioxide out, it would damage the ecosystem, seeing as a lot of carbon dioxide is toxic.

Food Web and Pyramid

100

What type of consumer is at the top of a food pyramid?

A tertiary consumer.

200

What type of consumer is at the top of a food pyramid?

Energy.

300

Is all energy in one organism passed to another once it's eaten, or only a portion of it?

Only a portion of the energy is passed to the organism that ate the other organism.

400

Is a food web made of one producer, one primary consumer, one secondary consumer, one tertiary consumer, and one decomposer, or multiple of each level, connecting in multiple places?

A food web is made of multiple of each level of the food chain, and each organism can be eaten by a bunch of the other organisms, connecting them to each other.

500

Why is it that certain animals can be both secondary and tertiary consumers?

Certain animals have the ability to eat both primary and secondary consumers. Like an owl can eat a mouse, which is a primary consumer, making the owl a secondary consumer in that case, but can eat a snake, a secondary consumer too.
