When both organisms gain something. 

What is Mutualism?

100

This biome, found in South America and Africa, is rich in life and has the highest biodiversity out of all land biomes.

What is the Tropical Rainforest?

100

The main gas responsible for climate change.

What is CO₂? (Carbon Dioxide)

100

This type of organism is always at the base of a food chain, converting sunlight into energy.

What are Producers?

100

This type of waste, commonly found in landfills, takes hundreds of years to break down and is often associated with packaging and containers.

What is Plastic?

200

When one organism is benefited and the other is neither helped or harmed.

What is Commensalism?

200

The Great Plains of North America are an example of this type of biome.

What is Grasslands?

200

This term describes the destruction of forests, often for agricultural or developmental reasons.

What is deforestation?

200

This is a type of organism that feeds on dead or decaying organic matter, playing an essential role in recycling nutrients.

What is a Decomposer?

200

This process involves breaking down organic waste into nutrient-rich material that can be used to enrich soil.

What is Composting?

300

When one species benefits and the other is harmed.

What is Parasitism?

300

What State in the USA holds the largest temperate rainforest in the world?

What is Alaska?

300

These tiny plastic particles, often less than 5 millimeters in size, are found in oceans, freshwater, and even the air, posing a threat to wildlife and human health.

What are microplastics? 

300

This term refers to an organism that eats both plants and animals in a food chain.

What is an Omnivore?

300

This symbol, often seen on recyclable items, indicates that the material is recyclable but not necessarily accepted in all curbside programs.

What is the Recycling Symbol?

400

Symbiotic relationship between a Shark and Remora fish.

What is Commensalism?

400

This type of water ecosystem is where freshwater from rivers meets with the saltwater from oceans.

What is an Estuary?

400

This environmental disaster, caused by excessive carbon dioxide absorption, lowers ocean pH and threatens marine life such as coral reefs.

What is Ocean Acidification?

400

This type of organism consumes primary consumers and is often at the top of the food chain.

What is a Quaternary Consumer?

400

This type of plastic, often used in bottles and containers, is one of the most commonly recycled plastics. Its recycling code is #1.

What is PET or Polyethylene Terephthalate?

500

When two organisms compete for the same food source, it is an example of this type of interaction, where both species are harmed by having less access to resources.

What is Competition?

500

This unique biome finds its home in California, and it includes much of both coastal and central California. It’s characterized by hot, dry summers and mild, rainy winters.

What is a Chaparral (shrubland)?

500

This phenomenon, caused by excess nutrient runoff from agriculture and wastewater, leads to massive algal blooms that deplete oxygen in water, creating "dead zones" where marine life cannot survive.

What is Eutrophication?

500

This term describes the interconnected system of feeding relationships in an ecosystem, where energy and nutrients flow through various organisms.

What is a Food Web?

500

This is the term for waste that cannot be recycled or composted and is typically sent to landfills or incinerators.

What is non-recyclable waste? (Trash)
