These break down organic matter

What are decomposers? 

100
Sun-> Grass -> Grasshopper -> Gecko -> Owl, This is the producer. 

What is grass? 

100

Much of the water on land runs off into these 2 bodies of water. 

What are lakes and oceans? 

100

This is the process of gradual, natural change and species replacement in an ecosystem over time.

What is succession? 

100

Organisms that hunt and eat other organisms

What are predators? 

200

The process used by autotrophs to make food energy from the sun is called this. 

What is photosynthesis? 


200

Sun-> Grass -> Grasshopper -> Gecko -> Owl, this is the 3rd level consumer.

What is owl? 

200

This is what happens when water in the atmosphere cools. 

What is condensation? 

200

This succession takes place on land where there are no living organisms. 

What is primary? 

200

Any relationship were 2 species live closely with each other. 

What is symbiosis? 

300

Organisms that rely on other organisms for their energy are called this. 

What are heterotrophs? 

300

Sun-> Grass -> Grasshopper -> Gecko -> Owl, this is the herbivore

What is the grasshopper? 

300

This is what happens when droplets become large enough and fall back to earth. 

What is precipitation? 

300

The first species to live in the area, once cooled off, are called this.

What are pioneer species? 

300

Both species benefit from the relationship

What is mutulism? 


400

Organisms that make their own food are called this

What are producers? 

400

Sun-> Grass -> Grasshopper -> Gecko -> Owl, this is the main energy source of the food chain.

What is the sun? 

400

Most water molecules enter the atmosphere after doing this. 

What is evaporating? 

400

This succession is a pattern of change that takes place after an existing community is destroyed, such as a wildfire. 

What is secondary? 

400

All strategies and adaptations a species uses for survival. 

What is niche? 

500

Chemosynthesis is a way an organisms can produce energy without this

What is sunlight? 

500

Sun-> Grass -> Grasshopper -> Gecko -> Owl, second level consumer. 

What is the gecko? 

500

This happens when water goes from the leaves to the atmosphere from leaves. 

What is transpire? 

500

After time passes, little or no change

occurs – when this is the case, this community is called this. 

What is climax community? 

500

Non-living parts of an environment

What are abiotic factors?
