When one animal hunts and eats another animal for food, this relationship is called_________

What is a predation

100

A food chain always begins with organisms like plants that make their own food using sunlight. 

What are producers? 

100

This term describes all the living and nonliving things in an area interacting together. 

What is an ecosystem?

100

This term means all the living and nonliving things interacting in one area. 

What is an ecosystem? 

100

This biome is very dry and receives little rainfall. 

What is the desert? 

200

In This relationship, one organism benefits while the other is not helped or harmed, like barnacles living on whales. 

What is commensalism? 
200

This shows a single pathway of energy transfer from one organism to another. 

What is a food chain? 

200

Plants are placed in this group because they make their own food using sunlight. 

What are producers? 

200

These are the living parts of an ecosystem, such as plants, animals, and bacteria. 

What are biotic factors? 

200

Grasslands support large grazing animals and receive more rain than deserts but less than forests. 

What is the grassland? 

300

This relationship benefits both organisms, such as cleaner fish removing parasites from larger fish. 

What is mutualism? 

300

This diagram shows many connected food chains and how energy moves through an ecosystem. 

What is a food web? 

300

A food web is different from a food chain because it shows this. 

What are many connected feeding relationships or multiple food chains? 


300

Sunlight → grass → rabbit → hawk is an example of this.

What is a food chain? 

300

This term describes an organism's role or job in an ecosystem.

What is food? 

400

When two animals compete for the same limited resource, like food or territory, this relationship is called_______

Competition? 

400

Organisms like snakes, frogs, and birds that eat other animals for energy are called______

What are consumers? 

400

This type of relationship benefits one organism, while the other is neither helped nor harmed.

What is commensalism? 

400

The nonliving parts of an ecosystem, such as water, sunlight, soil, and temperature, are called these. 

What are abiotic factors? 


400

Removing a keystone predator often causes this type of chain reaction throughout the food web. 

What is a trophic casade? 

500

In this relationship, one organism benefits while the other is harmed, such as ticks feeding on a deer. 

What is parasitism? 

500

IF the number of producers in an ecosystem decreases, this will most likely happen to the rest of the food web. 

What is the population of consumers will decrease due to less available energy/food 

500

When a population grows too large for its resources, factors like food, space, and predators limit growth. These factors are called this. 

What are limiting factors? 

500

If a disease reduces the number of rabbits in an ecosystem, this will most likely decrease next. 

What is the population of predators that eat rabbits. 

500

Sea otters are a keystone species because they keep this animal's population under control. 

What are sea urchins?
