These organisms get their energy straight from the sun.

What are producers?

100

This is the process of creating offspring.

What is reproduction?

100

What led to the trophic cascade in the Yellowstone National Park that changed the entire ecosystem and landscape?

Removal of the wolves by hunting.  Reintroducing the wolves as apex predators helped restore the ecosystem.  

100

When one species impacts another, not directly, but through the influence of a third species or through changes in the environment

Indirect effect

100
This is the whale described in the articles that lives in the arctic sea.

What are Orca (killer whales)?

200

This is the vocabulary word for the organisms that are eaten.

What is the resource population?

200

This will happen to the population size if organisms get more energy resource molecules.

What is grow/increase/more births?

200

This is the name for the process where algae use sunlight to make their own food.

What is photosynthesis?

200

an ecological phenomenon where a change at one trophic level (food chain level) in a food web has cascading effects on other levels, often leading to significant shifts in the structure and function of an ecosystem.

Trophic Cascade

These are the tiny floating food source for the Jellies in the Arctic Sea.

What are zooplankton?

300

This is the population that eat other organisms.

What is the consumer population?

300

This will happen to the population if another food  competitor increases.

What is decrease/shrink/less births?

300

These are the names of the tiny blue insects in the Amplify simulator.

What are weebugs?

300

Scientists have been studying the size of three populations in a swampland. In this ecosystem, herons (a type of bird) eat frogs, and frogs eat dragonflies. The data showed that all three populations were stable. Then the dragonfly population increased suddenly. What will likely happen to the frog population as a result?

increase. The larger dragonfly population will provide more energy storage molecules for the frog population, so they will reproduce more. This will lead to more births than deaths in the frog population.

300

These fish compete with the jellies for food in the Arctic Sea.

What are Walleye Pollock?

400

These organisms eat dead and decaying matter to return nutrients to the soil.

What are decomposers?

400

This will happen to the population if there are more deaths than births.

What is decrease/drop/get smaller?

400

These organisms eat the kelp that grows in the Arctic Sea.

What are Sea Urchins?

400

In North America, both bears and eagles eat trout. The sizes of the populations have been stable for the last 9 years, but recently the size of the eagle population decreased. What will likely happen to the bear population?

increase. The smaller eagle population will leave more energy storage molecules for all other populations in the ecosystem, so all populations will reproduce

400

These mammals migrate from the arctic down to California coast to reproduce.

What are elephant seals?

500

This is the word for what happens when two different species eat the same food.

What is competition?

500

This is the term for a change that occurs that was not directly from the resource or consumer populations.

What is indirect effect?

500

This is another example of an energy storage molecule besides glucose.

What is protein/lipid/fat/carbohydrate?

500

A population of bluefish lives in the Gulf of Mexico. Over the last 50 years, the size of the bluefish population has decreased. What best explains the decrease in the size of the bluefish population?

More bluefish deaths than births.
500

This organism has special spines in its mouth to help it eat jellies.

What is the Leatherback Turtle?
